Product details

Automotive-grade transient suppression for 70 V rails

The 1.5KE82CAHE3_A/D is a bidirectional TransZorb® TVS diode from Vishay's automotive-qualified series, designed to clamp transients on 70.1 V nominal rails in 12 V, 24 V, and 48 V automotive systems where load-dump and inductive kickback are present.

Clamping voltage and breakdown margins

The 70.1 V reverse standoff voltage means it conducts negligible leakage below that threshold, keeping the protected rail clean during normal operation.

Package and assembly integration

Housed in the DO-201AA (DO-27) axial-lead through-hole package, the device is wave-solder compatible and mounts through a single drilled hole per lead, with the body standing off from the board for convective cooling. The axial form factor suits point-to-point wiring in power distribution boxes or hybrid relay panels where surface-mount parts would risk solder-joint fatigue under vibration.

Frequently asked questions

What is the clamping performance of this TVS diode?

It clamps at 113 V maximum when conducting 13.3 A of peak pulse current (10/1000 µs waveform). The breakdown voltage starts at 77.9 V minimum, so the device triggers well before the 113 V ceiling.

What compliance documentation does Vishay provide for this part?

AEC-Q101 qualification documentation and PPAP files are available from Vishay for this automotive-grade series. RoHS and REACH compliance status is standard for the TransZorb® product line.
