1.5KE120A Description

Short technical summary and product information.

The 1.5KE120A is a 1500W unidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 102V and a clamping voltage of 212V at a peak pulse current of 47A (8/20µs waveform). The device can handle 1500W peak pulse power (10/1000µs waveform) and offers a fast response time of less than 1ps from 0V to breakdown voltage. It provides ESD protection up to 30kV air and contact per IEC 61000-4-2.

 

The TVS diode is housed in a DO-201AA/DO-27 axial leaded package with through-hole mounting and matte tin termination finish. It operates over a junction temperature range of -55°C to 175°C and has a typical thermal resistance of 15°C/W junction-to-lead and 75°C/W junction-to-ambient. The device is RoHS3 compliant, halogen free, and lead-free (Pb-free E3). It is suitable for general purpose transient protection in applications such as I/O interfaces, VCC bus, telecom, computer, industrial, and consumer electronics.
