Product details

Obsolete — sourcing through independent channels

The 1.5KE36AHE3/51 is marked Obsolete by Vishay, meaning the manufacturer no longer produces it.

1500 W peak pulse — clamping at 49.9 V

The 30.8 V reverse standoff means the protected rail stays below the clamping threshold during normal operation; breakdown starts at 34.2 V minimum.

AEC-Q101 qualified — -55 to 175 °C

Part of the Automotive, AEC-Q101 qualified TransZorb® series, this diode is screened for automotive-grade reliability. The -55 to 175 °C operating junction range covers under-hood and engine-bay thermal profiles without derating at the high end.

DO-201AA axial — through-hole mounting

Supplied in the DO-201AA (DO-27) axial-lead package, the 1.5KE36AHE3/51 is a through-hole part. The axial body suits point-to-point wiring or PCB mounting where the lead bend radius and hole diameter match the standard DO-201 footprint.

Frequently asked questions

How do I get current pricing and availability for 1.5KE36AHE3/51?

Submit an RFQ for the quantity you need. No stock or price figures are published here.

What is the closest pin-compatible alternative to 1.5KE36AHE3/51 in this Circuit Protection family?

A functionally equivalent TVS with the same 1500 W rating, 30.8 V standoff, and DO-201AA package would need to be selected from the active TransZorb® or another manufacturer's portfolio — pinout is identical for axial-lead devices of the same package.

What is 1.5KE36AHE3/51's listed type (Zener) on this Circuit Protection line?

The type is Zener — specifically a Zener-based transient voltage suppressor (TVS) diode. It uses the avalanche breakdown of a Zener junction to clamp transients.

What compliance documentation does Vishay General Semiconductor - Diodes Division provide for 1.5KE36AHE3/51 (RoHS, REACH, UL, IEC)?

The evidence does not list specific compliance documentation. As an obsolete part, the original datasheet and any RoHS/REACH declarations from the production period would be the reference — confirm with the sourcing channel at RFQ.
