| FFF Compatibility | The part utilizes the standard DO-204AC (DO-15) axial-lead footprint with the identical anode/cathode pin mapping, enabling an instant drop-in replacement.The axial package outline, lead spacing, and body dimensions match standard JEDEC DO-15 specifications.Key electrical parameters match or exceed the original: reverse standoff voltage is 10.2V, minimum breakdown is 11.4V, and peak power handling is 600W. | Matches the standard DO-204AC (DO-15) axial package and polarity layout exactly.Dimensions strictly follow the DO-15 physical outline with identical mounting characteristics.Has equivalent reverse standoff (10.2V), breakdown (11.4V), clamping voltage (16.7V), and peak power rating (600W). | ||
 AI Summary | P6KE12A by Taiwan Semiconductor: 16.7V Clamp 36A Ipp Tvs Diode Through Hole DO-204AC (DO-15). | This is a direct manufacturer-recommended substitute that offers identical standoff voltage and clamping limits. It provides a slightly wider operating temperature window up to 175°C and marginally improved transient current survival.
| This alternative from Vishay's well-established TransZorb® line provides exceptional transient voltage suppression. It matches the critical electrical ratings while extending the maximum operating temperature limit.

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 Taiwan Semiconductor P6KE12A is active and in production. The parts listed here are qualified equivalents if you need a second source or better availability.
The closest qualified second sources for the Taiwan Semiconductor P6KE12A are the P6KE12A (Littelfuse Inc.) and the P6KE12A-E3/54 (Vishay General Semiconductor - Diodes Division), out of 6 matched alternatives in total.
