P6KE43CA Description

Short technical summary and product information.

The P6KE43CA is a 600W bidirectional Zener TVS diode designed to protect sensitive electronic equipment from voltage transients. Manufactured by Littelfuse Inc., this device offers a reverse standoff voltage of 36.8V and a maximum clamping voltage of 59.3V at a peak pulse current of 10.3A (10/1000µs waveform). It is part of the P6KE series known for fast response time and excellent clamping capability.

 

With a peak pulse power dissipation of 600W, the P6KE43CA is suitable for general purpose transient voltage suppression in telecom, computer, industrial, and consumer electronic applications. The device is bidirectional with a single channel, making it ideal for protecting I/O interfaces and VCC bus lines.

 

The P6KE43CA comes in a through-hole DO-204AC (DO-15) axial leaded package, compatible with high temperature reflow soldering (260°C/30s). It operates over a junction temperature range of -55°C to 175°C and is RoHS3 compliant, lead-free, and halogen-free.
