P4KE300CA Description

Short technical summary and product information.

The P4KE300CA is a 400W bidirectional TVS diode from the Littelfuse P4KE series, designed to protect I/O interfaces, VCC bus, and other vulnerable circuits from transients. It offers a single bidirectional channel with a reverse standoff voltage (V_RWM) of 256V and a clamping voltage (V_C) of 414V at the rated peak pulse power.

 

Key electrical characteristics include a peak pulse power dissipation of 400W (10/1000μs waveform), fast response time of less than 1.0ps from 0V to V_BR min, and IEC 61000-4-2 ESD protection of 30kV air and 30kV contact. The device also provides a peak forward surge current (I_FSM) of 60A (8.3ms, unidirectional) and a steady state power dissipation of 1.5W.

 

The P4KE300CA is packaged in a DO-204AL (DO-41) axial leaded through-hole package. It operates over a junction temperature range of -55°C to 175°C, with typical thermal resistance of 60°C/W junction-to-lead and 100°C/W junction-to-ambient. The device is RoHS3 compliant, halogen free, and lead-free with Pb-free E3 tin terminal finish.

 

This TVS diode is suitable for general purpose transient protection in telecom, computer, industrial ICT, and consumer electronics, offering reliable clamping and ESD protection for sensitive circuits.
