Product details

1.5 kW peak pulse, AEC-Q101 qualified

The 1.5KE27AHE3_A/C is a 1500 W peak-pulse power TVS diode from Vishay's TransZorb series, rated for unidirectional protection on a single 23.1 V standoff rail. Breakdown voltage minimum is 25.7 V; clamping is held to 37.5 V at the 40 A peak-pulse current (10/1000 µs waveform).

Through-hole package and thermal envelope

Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE27AHE3_A/C is a through-hole device intended for hand or wave soldering. The operating junction temperature range spans -55°C to 175°C, covering the full automotive underhood ambient and hot-soak conditions. The base product number is 1.5KE27; the /A suffix indicates a 5% tolerance on breakdown voltage. No power-line protection is claimed — this is a general-purpose transient suppressor, not a mains-rated device.

Frequently asked questions

Is 1.5KE27AHE3_A/C AEC-Q101 qualified?

Yes, the series is listed as Automotive, AEC-Q101, TransZorb — the AEC-Q101 qualification covers the automotive reliability stress and PPAP documentation required for OEM programs.
