P4KE550CA Description

Short technical summary and product information.

The P4KE550CA is a bidirectional TVS diode from Littelfuse designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 495V and a clamping voltage of 760V at a peak pulse current of 520mA. With a peak pulse power rating of 400W (10/1000μs waveform), it is suitable for applications such as I/O interfaces, VCC bus, telecom, computer, and industrial ICT equipment.

 

The device uses a Zener-type glass passivated chip junction in a DO-204AL (DO-41) axial leaded package, allowing through-hole mounting. It offers fast response time (typically less than 1ps) and operates over a junction temperature range of -55°C to 175°C. The part is bidirectional with one channel, making it ideal for protecting circuits from both positive and negative transients.

 

Compliance data indicates RoHS3 and REACH unaffected status, though these are unverified. The datasheet referenced is for a different part number (P4KE6.8ACT-ND), so key parameters like breakdown voltage and reverse leakage current are not confirmed for this specific model.
