1.5KE170CA Description

Short technical summary and product information.

The 1.5KE170CA is a bidirectional Zener TVS diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 145V and a clamping voltage of 234V at a peak pulse current of 6.5A (10/1000μs waveform). With a peak pulse power dissipation of 1500W, it is suitable for general purpose transient protection in telecom, computer, industrial, and consumer applications. The device has a fast response time of less than 1.0ps from 0V to breakdown voltage. It is housed in a through-hole DO-201AA/DO-27 axial leaded package, with an operating temperature range of -55°C to 175°C. The part is RoHS3 compliant and halogen free.
