1.5KE22A Description

Short technical summary and product information.

The 1.5KE22A is a unidirectional Zener TVS diode from Littelfuse's 1.5KE series, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events.

 

This component offers a peak pulse power dissipation of 1500W (10/1000µs waveform) with a clamping voltage of 30.6V. It features a fast response time of less than 1.0ps and is capable of handling a peak pulse current of 49.7A. The device is also rated for ESD protection per IEC 61000-4-2 (30kV air, 30kV contact) and is compliant with IEC 61000-4-4 for EFT protection.

 

Packaged in a DO-201AA (DO-27) axial leaded through hole package, the 1.5KE22A has an operating temperature range of -55°C to 175°C and a steady state power dissipation of 6.5W. The junction is glass passivated for reliability.
