5KP28A Description

Short technical summary and product information.

The 5KP28A is a 5kW peak pulse power TVS diode from Littelfuse, designed for transient voltage protection. It features a reverse standoff voltage of 28V and a clamping voltage of 45.4V, with a peak pulse current rating of 112.3A. The diode has a fast response time of less than 1.0ps, making it suitable for protecting sensitive circuits from fast transients.

 

This unidirectional TVS diode is packaged in a P600 axial through-hole package, suitable for through-hole mounting. It operates over a temperature range of -55°C to 175°C and has a steady state power dissipation of 8.0W. The device is RoHS, halogen free, and lead-free compliant.

 

Typical applications include general purpose protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The 5KP28A is part of the 5KP series from Littelfuse, known for its robust surge protection capability.
