P4KE20CA Description

Short technical summary and product information.

The P4KE20CA is a 400W bidirectional transient voltage suppression (TVS) diode from Littelfuse Inc., designed to protect sensitive electronic equipment from voltage transients induced by lightning, ESD, and EFT events. It features a reverse standoff voltage of 17.1V, a breakdown voltage of 19V, and a maximum clamping voltage of 27.7V at a peak pulse current of 14.8A (10/1000µs waveform).

 

The device offers a fast response time of less than 1.0ps from 0V to Vbr min, and a peak forward surge current capability of 60A (8.3ms single half sine wave). It is housed in a DO-204AL (DO-41) axial-leaded through-hole package, suitable for automated insertion and high-temperature reflow soldering up to 260°C.

 

Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial ICT equipment, and consumer electronics. The P4KE20CA is halogen-free and lead-free (Pb-free E3), with an operating temperature range of -55°C to 175°C.
