 AI Summary | BAT54C by onsemi: Diode Array 1 Pair Common Cathode 30 V 200mA Surface Mount TO-236-3, SC-59, SOT-23-3. | This is a direct, industry-standard drop-in alternative with an active lifecycle status. It matches all physical and electrical parameters of the obsolete Good-Ark part, offering a slightly improved forward voltage drop for higher efficiency.
| This active alternative from Nexperia is an excellent high-reliability replacement. It meets or exceeds all physical and electrical specifications, including the full -65°C to 150°C operating temperature range.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The onsemi BAT54C is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the onsemi BAT54C are the BAT54C-7-F (Diodes Incorporated) and the BAT54C,215 (Nexperia USA Inc.), out of 6 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Yes. The leading alternatives to the BAT54C are fit-, form- and function-compatible — the same package and pinout with matching key electrical specifications — so they drop in without PCB changes. Always confirm the parameters critical to your design against the alternative's datasheet before committing.
The BAT54C (onsemi) is a part in the Diodes category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
