Product details

Clamping a 102 V rail in an automotive ECU

The 1.5KE120CAHE3_A/C is a 1500 W bidirectional TransZorb TVS from Vishay, qualified to AEC-Q101 for automotive use. Its 102 V reverse standoff voltage means it sits across a nominal 100 V bus without conducting leakage, then clamps transients at 165 V maximum.

Breakdown and clamping window

Minimum breakdown voltage is 114 V, so the device starts conducting between 114 V and the 165 V clamp ceiling. The 9.1 A peak pulse current rating (10/1000 µs waveform) confirms it can absorb the surge energy from a load-dump or inductive kickback event on a 100 V nominal bus.

Package and sourcing posture

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE120CAHE3_A/C is a through-hole part suited for point-of-use transient suppression on power input stages. The base product number is 1.5KE120, and the HE3 suffix denotes the AEC-Q101 automotive grade. Vishay lists this part as Active in production.

Frequently asked questions

What is the peak pulse power rating of 1.5KE120CAHE3_A/C?

The device is rated for 1500 W (1.5 kW) peak pulse power dissipation. This is the 10/1000 µs waveform rating — the actual peak current it can handle is 9.1 A, clamping at 165 V maximum.

What compliance documentation does Vishay provide for this part?

As an AEC-Q101 qualified automotive component, Vishay provides PPAP documentation, RoHS compliance data, and the full qualification test report on request. The TransZorb series is also UL recognized under file E54222.
