P4KE400CA Description

Short technical summary and product information.

The Littelfuse P4KE400CA is a bidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients, EFT, and ESD. It offers 400W peak pulse power capability at 10/1000μs waveform.

 

With a reverse standoff voltage of 342V and maximum clamping voltage of 548V at 750mA peak pulse current, this diode ensures robust clamping. It features a fast response time of typically less than 1ps from 0V to breakdown voltage.

 

The device is housed in a through-hole DO-204AL (DO-41) axial leaded package, suitable for general purpose applications in telecom, industrial ICT equipment, and consumer electronics.

 

Operating temperature range from -55°C to 175°C. The P4KE series is glass passivated for reliability and RoHS3 compliant with halogen-free and lead-free construction.
