The AWSS10H100 is a 10 A, 100 V Schottky barrier rectifier in an eSGC (TO-277) package from Good-Ark, positioned on the Good-Ark site for automotive lighting and ECU power. It is the top of the AWSS current and voltage grid, and its full electrical specifications are confirmed with the supplier. This article covers the positioning, the dual load profiles, and the confirmation list.
The 10 A/100 V Sweet Spot in Automotive Power
The 10 A, 100 V class is the automotive board-level sweet spot: 10 A covers the high-current lighting strings and ECU rails, and the 100 V class covers the 24 V systems and the transient-heavy modules with margin. The class sits at the top of the AWSS grid, where the current and the voltage meet the automotive power paths that need both.
The class also sits inside the eSGC package’s capability band: the exposed pad and the board copper carry the 10 A heat, and the compact body fits the dense automotive module. The package and the class are the fit.
The 10 A class also sets the thermal expectation: at 10 A, a 0.1 V drop is 1 W of heat in the sealed module, and the low-drop class is the lever the thermal design reads. The class decision and the thermal design are the same number, read together.
The 100 V class also costs a higher forward drop than the 60 V rung, and the class decision follows the measured reverse peak with the margin rule—the 100 V class is chosen where the transients demand it, and the 60 V class where the clean rail allows the efficient choice. The 10 A class also sets the surge story: the worst inrush and the start events are checked against the surge column with the count in the margin, and the sealed module’s thermal budget carries the result.
The 100 V class also costs a higher forward drop than the 60 V rung, and the class decision follows the measured reverse peak with the margin rule—the 100 V class is chosen where the transients demand it, and the 60 V class where the clean rail allows the efficient choice.
AWSS10H100 at a Glance
The site-verified information: a 10 A, 100 V Schottky in eSGC (TO-277), positioned for automotive lighting and ECU power. The datasheet is not yet published on the site, and the full electrical values—forward drop, leakage, surge, thermal resistance, and qualification status—are confirmed with the supplier before design-in.
ECU vs Lighting: Two Load Profiles, One Part
The ECU and lighting roles load the part differently. An ECU rail runs a steady current with the module’s transients, and the 10 A rating covers the rail with margin at the case temperature. A lighting string runs a current that dims with the driver, and the 10 A rating covers the full-current point with the dimmed states below it. The part serves both because its rating covers the current and voltage envelope both roles share.
The two profiles also share the thermal story: the sealed module’s ambient and the exposed-pad board path are the same for both, and the case-temperature measurement at the worst condition is the acceptance test for either role.
The ECU rail’s steady current and the lighting string’s dimmable current also differ in the surge story: the ECU sees the module’s transients, and the lighting sees the dimming steps and the harness events. The surge column is checked against each role’s worst event, with the count in the margin.
The two roles also share the qualification story: the part’s automotive wording is read literally and confirmed with the supplier, and the program’s approval reads the same evidence for either application.
Unpublished Datasheet: Confirmation List
The confirmation list for design-in includes the forward drop at the working current, the leakage at the hot junction, the surge capability at the worst event, the thermal resistance with the mounting assumption, and the AEC-Q101 wording. None is assumed until the supplier provides the datasheet, and the qualification status is read literally—the AWSS family is not marked qualified on the site at this writing.
The confirmation list also includes the reliability data the board design reads: the thermal-cycling behavior of the exposed-pad joint, the derating curve at the module’s temperatures, and the moisture-handling class. The package and the board are a reliability pair, and the supplier’s data is the pair’s documentation.
Platform Qualification and Samples
The [AWSS10H100 product page](https://en.goodark.
The platform qualification runs the part through the same gates the family shares: the datasheet confirmation, the electrical checks at the platform’s conditions, the board design for the shared eSGC footprint, and the prototype validation with the case-temperature measurement. The qualification record is the platform’s evidence, filed with the revision dates, and the part’s value is realized through the confirmation and the validation that the record documents. > Design note. The AWSS10H100 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 no value is assumed before the datasheet is received.
Frequently Asked Questions
What does the site publish about the AWSS10H100?
The ratings (10 A, 100 V), the eSGC (TO-277) package, and the target market (automotive lighting and ECU). The full electrical specifications are confirmed with the supplier.
Why is the 10 A/100 V class the sweet spot?
It covers the high-current lighting strings and ECU rails with the 100 V margin for 24 V and transient-heavy systems—the top of the AWSS grid.
How do the ECU and lighting loads differ?
The ECU runs a steady rail current with transients, and the lighting runs a dimmable string; the 10 A rating covers both envelopes, and the thermal story is shared.
What must I confirm before design-in?
The forward drop, leakage, surge, thermal resistance, and AEC-Q101 wording, from the supplier’s datasheet—none assumed from the site’s published set.
How do I get the datasheet and samples?
Through the supplier with your platform’s conditions, confirmed against the current revision.
