The AWSS family covers the automotive lighting and ECU domain with four parts in one footprint: 5 A and 10 A, crossed with 60 V and 100 V, all in eSGC (TO-277). This guide maps the lineup, matches the load, and walks the sample and validation strategy.
Four Parts, One Family: The AWSS Lineup Map
| Part | Current | Voltage | Package | Target market |
|---|---|---|---|---|
| AWSS5H60 | 5 A | 60 V | eSGC (TO-277) | Lighting & ECU |
| AWSS5H100 | 5 A | 100 V | eSGC (TO-277) | Lighting |
| AWSS10H60 | 10 A | 60 V | eSGC (TO-277) | Lighting |
| AWSS10H100 | 10 A | 100 V | eSGC (TO-277) | Lighting & ECU |
The map is the family’s value: four part numbers, one footprint, and the ratings grid covers the automotive lighting and ECU current and voltage domain. The site publishes the ratings, package, and target market for each; the full electrical specifications are confirmed with the supplier.
The map also shows the family’s boundary: the 60 V class serves the clean 12 V rails, the 100 V class the 24 V and transient-heavy systems, and the 5 A and 10 A classes the light and heavy current paths. The grid covers the domain without gaps, and the load match picks the cell.
The map also sets the family’s reliability story: the four parts share the eSGC package and its thermal behavior, and the qualification and the board design are family-level, not part-level. The family is a platform asset, and the map is its index.
Matching the Load: Current and Voltage Fit
The load match runs two gates. The current gate: the part’s rating covers the string or rail current with margin, at the module’s case temperature—a 1–3 A lighting string fits the 5 A parts, and a 5–8 A ECU rail fits the 10 A parts. The voltage gate: the class covers the worst reverse peak with the 20–30% margin from the voltage rating method—60 V for a clean 12 V rail, 100 V for the 24 V or transient-heavy systems.
The two gates are read at the working condition, and the leakage and thermal checks follow in the same pass.
The load match also reads the duty: a lighting string that dims runs a range of currents, and the part is chosen for the full range, not the full-current point alone. An ECU rail runs a steady current with the module’s transients, and the part covers the rail with margin at the case temperature.
The load match closes with the thermal check: the part’s loss at the working current, the leakage at the hot junction, and the case temperature at the sealed condition are the three numbers the board design closes, and the family’s shared footprint keeps the board design constant across the range.
Package Consistency: One eSGC Footprint, Multiple Ratings
The shared eSGC footprint is the family’s production value: one pad design, one stencil, and one board layout serve all four parts, so a load that changes current or voltage class changes the part number without a board revision. The footprint rules follow the TO-277 guide, and the exposed pad’s heat path is the same across the family.
The consistency also simplifies the qualification and the inventory: one footprint to qualify, one reel position per rating, and one board to validate across the family’s range.
The shared footprint also softens the late-change risk: a transient discovery that moves the design from 60 V to 100 V, or from 5 A to 10 A, changes the part number without a board revision. The family’s consistency is the design’s insurance against the load-profile surprises the automotive world delivers.
The inventory story is the production half: four part numbers on one reel format and one footprint mean the line holds fewer unique board setups, and the changeover between ratings is a part-number change, not a process change. The family’s production value compounds at volume.
Sample and Validation Strategy for a New Platform
- Confirm the datasheets for the two candidate parts (the current and voltage class that fit).
- Run the gate checks at the platform’s conditions.
- Build one board that accepts the shared footprint and validate both candidates.
- Measure the case temperature, efficiency, and surge margin at the worst condition.
- Confirm the qualification wording and lock the part number.
The strategy validates the family, not just the part: one board, two candidates, and the shared footprint prove the design’s range.
The strategy also runs the reliability checks: the thermal cycling of the shared joint, the derating at the module’s temperatures, and the qualification wording are validated once for the footprint and confirmed per part number. The validation record is the family’s evidence, and the platform’s approval reads it.
The strategy closes with the production handoff: the board design, the stencil, the inspection plan, and the part-number selection are filed together, and the production line runs the family with the same discipline the validation used. The family is a platform asset from validation to volume.
Official Specification Access
The AWSS5H60 product page and its siblings on the Good-Ark site are the entry, and the full specifications are requested through Good-Ark sales with the platform’s current, voltage, and thermal conditions. The datasheets, the qualification status, and the samples are confirmed against the current revision.
The specification access is the family’s official gate: the site publishes the verified set, and the supplier’s datasheet is the contract the design reads. The request and the confirmation are the handshake between the platform and the family, documented at every step.
The family guide also sets the review expectation: the platform reads the four-part map against its load profile, confirms the datasheets, and validates the shared footprint on one board. The family’s value is realized when the guide’s steps are followed, and the record is the platform’s evidence. The platform that reads the map, runs the gates, and validates the footprint is the platform that uses the family fully.
The family’s four-part map also reads the reliability and the qualification story: the shared eSGC footprint means one thermal-cycling behavior, one solder-joint inspection, and one board qualification across the range, and the family’s evidence is read once and applied four times. The automotive program that adopts the family carries one footprint’s reliability data into four part numbers, and the qualification record is the family’s shared asset. The AWSS family is not just a ratings grid—it is a platform’s reliability and production plan in one footprint.
The family guide’s closing message is the review it sets: the platform reads the four-part map, confirms the two candidate datasheets, and validates the shared footprint on one board, and the measurements close the selection. The AWSS family is a platform asset when the map, the match, and the validation are followed, and the record is the evidence the next platform reads.
The family guide also sets the review expectation: the platform reads the four-part map against its load profile, confirms the datasheets, and validates the shared footprint on one board. The family’s value is realized when the guide’s steps are followed—the map, the match, the footprint, and the validation—and the record is the platform’s evidence. The AWSS family is a platform asset precisely because its four parts and one footprint turn a lighting and ECU load profile into a short list with one board design.
The guide’s final message is the same as its first: the family covers the automotive lighting and ECU domain without gaps, the shared eSGC footprint keeps the board constant, and the supplier confirmation closes the gap between the site’s published set and the datasheet’s full specification. The platform that reads the map, runs the gates, and validates the footprint is the platform that uses the family fully.
Design note. The AWSS family information in this article is the site-verified set—ratings, package, and target market. The full electrical parameters, thermal data, and qualification status are confirmed with the supplier, and the family’s shared footprint is the basis for the validation strategy.
