Product details

Transient suppressor with AEC-Q101 pedigree — now obsolete

The 1.5KE82HE3/73 is a 1500 W unidirectional TVS Zener from Vishay's TransZorb® series, qualified to AEC-Q101 for automotive use.

Clamping and breakdown window

Breakdown voltage is guaranteed between 73.8 V and the clamp ceiling — the 118 V clamp at 12.7 A Ipp means a 48 V bus sees the TVS stay off below 66.4 V, then snap in hard during a surge. The 1500 W peak pulse rating (10/1000 µs) is the energy-handling floor for load-dump or inductive kickback events in an engine-bay environment. No power-line protection (the device is unidirectional, single-channel) — it protects one rail per package, typical for point-of-load clamping on sensor or actuator power feeds.

Frequently asked questions

What is the closest alternative to 1.5KE82HE3/73 in the same family?

A functionally similar TVS with the same 66.4 V standoff and 1500 W rating would require a new qualification — the AEC-Q101 pedigree is specific to this TransZorb series.

What compliance documentation does Vishay provide for 1.5KE82HE3/73?

The part carries AEC-Q101 automotive qualification, which implies PPAP-level documentation and reliability test data per the standard. RoHS and REACH compliance status should be confirmed on the specific date-code lot at RFQ — Vishay typically provides certificates for the TransZorb series.
