1.5KE100A Description

Short technical summary and product information.

The 1.5KE100A is a unidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 85.5V and a maximum clamping voltage of 178V at a peak pulse current of 56A (8/20µs waveform). The device can handle 1500W of peak pulse power.

 

This TVS diode is housed in a through-hole DO-201AA/DO-27 axial leaded package, suitable for automated insertion. It has a junction capacitance of 1150pF at 1MHz and an operating temperature range of -55°C to 175°C. The part is unidirectional with a single channel.

 

Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The device is lead-free and halogen-free per the generic series datasheet.
