1.5KE82A Description

Short technical summary and product information.

The 1.5KE82A is a unidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients. It has a reverse standoff voltage of 70.1V and a clamping voltage of 146V at 69A peak pulse current (8/20µs waveform). The device can absorb 1500W of peak pulse power (10/1000µs waveform) and is housed in a DO-201 (DO-201AA, DO-27, Axial) through-hole package. Key features include a fast response time of less than 1.0ps, a typical reverse leakage current of less than 1µA when VBR min exceeds 12V, and an operating junction temperature range of -55°C to 175°C. The part is RoHS3 compliant, halogen-free, and has a Pb-free E3 matte tin lead finish. Applications include I/O interface protection, VCC bus protection, and general transient protection in telecom, computer, industrial, and consumer electronics.
