P4KE30CA Description

Short technical summary and product information.

The P4KE30CA is a bidirectional TVS diode from Littelfuse's P4KE series, designed to protect sensitive electronic equipment from voltage transients. It features 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). The device can dissipate 400W of peak pulse power.

 

This TVS diode utilizes a glass passivated chip junction in a DO-204AL (DO-41) axial lead package, suitable for through-hole mounting. It offers fast response time typically less than 1.0ps and operates over a temperature range of -55°C to 175°C. The bidirectional configuration allows protection for both positive and negative transients.

 

Typical applications include I/O interfaces, VCC bus, telecom, computer, industrial ICT equipment, and consumer electronics. The P4KE30CA is compliant with IEC 61000-4-2 ESD (30kV air/contact) and IEC 61000-4-4 EFT standards, as per the P4KE series datasheet. Note that the available datasheet filename does not match this specific part number; verification of specifications is recommended.
