1.5KE27A Description

Short technical summary and product information.

The 1.5KE27A is a 1500W unidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronics from voltage transients. It has a working peak reverse voltage of 23.1V and a clamping voltage of 48.3V at a peak pulse current of 207A (8/20µs waveform). The device offers a fast response time of less than 1 ns and an ESD rating of >16 kV per Human Body Model.

 

This TVS diode is suitable for general purpose applications such as communication systems, power supplies, and industrial controls. It features a peak power dissipation of 1500W for a 1 ms pulse and a steady state power dissipation of 5.0W. The operating temperature range is -65°C to +175°C.

 

The 1.5KE27A is housed in a DO-201AA, DO-27 axial lead package with through-hole mounting. The lead style is axial, and the device is polarity marked with a cathode band. Pb-free packages are available as indicated by the part number suffix.
