Product details

Automotive-grade TVS for 23.1V rails

The Vishay 1.5KE27AHE3_B/C is a 1500W Zener transient voltage suppressor from the TransZorb® series, designed to clamp transients on 23.1V nominal DC rails.

Clamping and breakdown margins

With a 23.1V reverse standoff voltage, the device stays transparent to the protected rail during normal operation.

Through-hole package and reflow handling

The DO-201AA (DO-27) axial leaded package is a through-hole form factor, not a surface-mount part. The axial leads handle the thermal cycling of the 175°C junction without the solder-joint fatigue risk of a large SMD package on a hot board.

Frequently asked questions

What is the 1.5KE27AHE3_B/C's reverse standoff voltage and clamping voltage?

The reverse standoff voltage is 23.1V typical, meaning the TVS does not conduct leakage current on a nominal 23.1V rail. Breakdown starts at a minimum of 25.7V, and clamping is limited to 37.5V maximum at the 42A peak pulse current rating (10/1000µs waveform).

Is the 1.5KE27AHE3_B/C automotive qualified?

Yes, it carries AEC-Q101 qualification, which certifies the device for automotive-grade reliability — temperature cycling, ESD immunity, and high-temperature reverse bias stress are screened. The operating junction temperature range is -55°C to 175°C, covering under-hood and engine-bay environments.
