Product details

Obsolete — sourcing through independent channels

The 1.5KE13HE3/73 is listed as Obsolete by Vishay.

Automotive-grade transient protection

Part of the Automotive, AEC-Q101 qualified TransZorb series — this TVS diode is screened for the reliability and temperature demands of automotive electronics, including under-hood and chassis-mounted ECU applications.

Package and board fit

Supplied in a DO-201AA (DO-27) axial-lead through-hole package. The unidirectional design provides a single-channel clamping path for positive-voltage transients relative to ground.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5KE13HE3/73?

A functionally equivalent TVS diode with the same 1500W rating, 10.5V standoff, and DO-201AA package would need to be selected from the current TransZorb or similar automotive series, but no direct drop-in replacement is documented.
