Alternatives to STMicroelectronics 1.5KE220A
STMicroelectronics 1.5KE220A and its qualified second sources, compared on form, fit and function, stock, lifecycle and price — the same checks Parter runs inside a BOM.
Equivalent and substitute parts for STMicroelectronics 1.5KE220A
 1.5KE220ASTMicroelectronics |  1.5KE220A-GComchip Technology |  1.5KE220A-E3/54Vishay General Semiconductor - Diodes Division | |
|---|---|---|---|
| FFF Compatibility | Identical DO-201 footprint and terminal connections.Axial form factor dimensions are interchangeable with the original ST component.The standoff voltage is slightly lower at 185V compared to the original ST device's 188V. | The physical footprint matches, but the pin numbering scheme in the datasheet differs (1/2 vs. A/K).Both share the identical DO-201AA axial dimensions with a standard cathode band marking.The standoff voltage is slightly lower at 185V compared to the original 188V of the ST device. | |
 AI Summary | 1.5KE220A by STMicroelectronics: 388V Clamp 26A (8/20µs) Ipp Tvs Diode Through Hole DO-201. | Comchip Technology offers a green/halogen-free alternative in the standard DO-201 package. It aligns closely with the original device's performance profiles, making it a reliable and environmentally friendly second source.
| Vishay's TransZorb series provides exceptional reliability and is a major second source for the 1.5KE series. It aligns perfectly with the physical and clamping parameters of the original device, with only a minor 3V difference in standoff voltage.

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.
