Product details

Protection envelope — 1500 W peak pulse, 30.8 V standoff

The 1.5KE36A-B: The 30.8 V reverse standoff voltage means it stays transparent on a 24 V rail but starts conducting when the line exceeds 34.2 V breakdown — typical for protecting 24 VDC supplies, relay coils, or I/O modules in industrial control panels. Unidirectional — one channel per device, cathode banded. For AC or bidirectional lines you would need two devices or a bidirectional variant from the same 1.5KE family.

DO-201 axial — board-fit and replacement note

If you are replacing a blown part on an existing board, the lead spacing and body diameter match the common 1.5KE footprint; no layout change needed.

Frequently asked questions

Where can I buy the 1.5KE36A-B?

The 1.5KE36A-B is obsolete. Submit a request for the quantity you need.

What is the closest pin-compatible alternative to the 1.5KE36A-B?

No official pin-compatible successor is listed by Diodes Incorporated. The 1.5KE36A (without the -B suffix) shares the same electrical ratings and DO-201 package — functionally identical for most BOM positions. Verify the marking code and date code if substituting.
