The datasheet that decides a design must be the right revision from the right source, because an old or aggregated copy can carry parameters the current part no longer guarantees. For Good-Ark parts, the official datasheet comes from the product page and the company’s document resources, and verifying it means checking the revision, the part number and the consistency between the document and the product listing. This guide explains where to find Good-Ark datasheets and how to verify what you read before the numbers enter a design.
Where the official datasheets live
The official datasheets live on the Good-Ark product pages and the company’s document resources: each product page links the current PDF for its part number, and the document section organizes the datasheets and related files by product family.
The product page for a part number shows the package, the rating table and the datasheet link, and that link is the first place to download the current document. The company’s document resources group the datasheets by family, which helps when the buyer needs the whole series or an older revision for comparison. Distributor listings and aggregator sites also carry datasheets, but those copies can be old or reformatted, so they are starting points rather than the source of truth. The official page and the company’s document library are where the current revision lives, and the download date belongs in the design record.
Checking the revision and the part number
Verify the datasheet by checking the part number, the revision code and the date on the PDF, and confirm that the document’s title and rating table match the product page for the exact part you are designing in.
A datasheet PDF carries a part number, a revision identifier and a date, and the first verification is that all three match the part and the product page. A family datasheet that covers several part numbers must include the exact code being designed; a single-part datasheet must carry that code in its title and table. The revision matters because a newer revision can change a limit or add a note, and an old revision can carry a parameter the current part no longer guarantees. The verification record should note the revision and the download date, so a future review can tell whether the design used the current document.
Verifying the numbers you will design with
Verify the numbers by checking the test conditions next to each rating, comparing the product page’s summary with the PDF, and confirming the parameters that drive the design — voltage, current at temperature, thermal data and the application-specific rows.
A rating is only meaningful with its conditions: the case temperature for the current, the waveform for the surge, the gate voltage for RDS(on) or the test current for the breakdown. The verification compares the summary values on the product page with the PDF and reads the full table and curves for the design’s operating point. The parameters that drive the specific design — the ones that would fail the application if wrong — get the closest check. A discrepancy between the product page and the PDF, or between two PDF revisions, is a reason to stop and confirm with the manufacturer before the BOM is written.
What to do when the listing and the datasheet disagree
When a distributor listing or an aggregator copy disagrees with the official datasheet, treat the official document as the source of truth and flag the discrepancy: the listing may be old, the revision may differ, or the copy may have been reformatted incorrectly.
The discrepancy is a verification event, not a mystery: download the official PDF from the product page, compare the revision and the values, and note which document the design will use. If the listing shows a different voltage class, current or package, the part number on the listing may not be the same part or the data may be stale. The design record should name the official revision and the check date, so an audit can trace the numbers. Distributor data is convenient for search and comparison; the official datasheet is the contract.
Building a datasheet verification habit
Build the habit into the design process: download the official PDF, record the revision and date, verify the design-critical parameters with their conditions, and re-check the revision before the BOM and before production release.
The datasheet is checked at three points in a design: when the part is selected, when the BOM is finalized and before production release. Each check confirms the revision is current and the numbers still fit the design. The habit is especially important for parts in long-life products, where a revision published during the design can change a parameter. The record of revision and check dates turns the datasheet from a downloaded file into a traceable design input. The component that reaches production with a verified current datasheet is the one whose numbers can be defended in a review.
| Check | What to confirm | When |
|---|---|---|
| Source | Official page or document library | First download |
| Part and revision | Number, code and date match | Selection and BOM |
| Design parameters | Values with test conditions | Selection and review |
| Currency | Revision still current | Before release |
Selection summary
A worked example makes the verification concrete: an engineer downloads a datasheet from a distributor listing, sees a 600 W TVS rating and starts the design; the official PDF from the product page shows the current revision with a different test waveform and a note that clarifies the rating’s condition. The design record is corrected before the BOM, and the discrepancy is flagged to the sourcing team so the listing can be checked. The example is illustrative, but it shows why the official source and the revision check belong at the start of the design, not after a prototype uses a number the current part does not guarantee.
The revision check also protects the supply chain: when the sourcing team negotiates against a listing with stale data, the discrepancy can change the price or the lead time discussion, so the confirmed current revision belongs in the sourcing record alongside the design record. The habit keeps the official document at the center of both the engineering and the buying process.
Find and verify Good-Ark datasheets from the official sources: use the product page and the company’s document library, check the part number and revision, and record the verification date with the design.
The datasheet is the contract for the part, and the current official revision is the one that counts. Download from the official source, verify the design-critical numbers with their conditions, and re-check before release. The design that starts from a verified datasheet is the design that can defend its numbers.
For a specific part’s datasheet, start from the product center and the document resources; if a listing or an old revision disagrees with the current document, send the details through the contact page and the engineering team will confirm the current revision for the part number.
