1.5KE15 Description

Short technical summary and product information.

The 1.5KE15 is a unidirectional transient voltage suppressor diode from Diotec Semiconductor, designed for overvoltage and ESD protection in general-purpose applications. It features a reverse standoff voltage of 12.1V, a minimum breakdown voltage of 14.3V, and a maximum clamping voltage of 22V at 71A peak pulse current (10/1000µs waveform). With a peak pulse power rating of 1500W and steady state power dissipation of 6.5W, this device offers robust protection for sensitive circuits.

 

Housed in a through-hole DO-201AA/DO-27 axial package, the 1.5KE15 has an operating junction temperature range of -50°C to 175°C. The case material is UL 94V-0 rated, and the device weighs approximately 1 gram. It is suitable for commercial and industrial grade applications including overvoltage protection, ESD protection, and free-wheeling diode functions.

 

The datasheet confirms compliance with RoHS (exemption 7a), REACH, and Conflict Minerals requirements. The part is unidirectional and does not include power line protection.
