P4KE30A Description

Short technical summary and product information.

The P4KE30A is a 400W peak pulse power transient voltage suppressor (TVS) diode from Littelfuse, part of the P4KE series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), and electrical fast transients (EFT).

 

This unidirectional diode has a reverse standoff voltage of 25.6V and a maximum clamping voltage of 41.4V at a peak pulse current of 9.9A (10/1000µs waveform). It offers a fast response time of typically less than 1ps and low incremental surge resistance. The device operates over a junction temperature range of -55°C to 175°C.

 

The P4KE30A is housed in a DO-204AL (DO-41) axial leaded package with through-hole mounting. It is RoHS compliant, halogen free, and has a moisture sensitivity level of 1 (unlimited). The series datasheet also specifies a peak forward surge current of 60A (8.3ms) and steady state power dissipation of 1.5W.

 

Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial ICT equipment, and consumer electronics.
