1.5KE24CA Description

Short technical summary and product information.

The 1.5KE24CA is a 1500W transient voltage suppression diode from Littelfuse's 1.5KE series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. This bidirectional device has a reverse standoff voltage of 20.5V and a clamping voltage of 33.2V at a peak pulse current of 45.8A (10/1000μs waveform). It features a fast response time of less than 1.0ps and meets IEC-61000-4-2 ESD requirements up to 30kV air and contact discharge. The device is housed in a DO-201AA/DO-27 axial leaded package with matte tin termination, suitable for through-hole mounting. It operates over a junction temperature range of -55°C to 175°C and has a steady state power dissipation of 6.5W on infinite heat sink. Typical applications include I/O interfaces, VCC bus protection, and general purpose circuit protection in telecom, computer, industrial, and consumer electronics.
