The P4KE20A is a 400W unidirectional TVS diode from Littelfuse, part of the P4KE series. It features a reverse standoff voltage of 17.1V and a clamping voltage of 27.7V at a peak pulse current of 14.8A (10/1000µs waveform). The device is designed to protect sensitive electronic equipment from electrostatic discharge (ESD), electrical fast transients (EFT), and induced lightning surges.
Key electrical characteristics include a peak pulse power dissipation of 400W, a fast response time of less than 1ps from 0V to breakdown voltage, and an ESD rating of 30kV air and 30kV contact per IEC 61000-4-2. The diode has a maximum forward voltage of 3.5V (single die) or 5.0V (stacked die) at 25A, and a peak forward surge current of 60A (8.3ms single half sine wave). It operates over a junction temperature range of -55°C to 175°C.
The P4KE20A is housed in a DO-204AL (DO-41) axial leaded package with through-hole mounting. It features a glass passivated chip junction for reliability and low incremental surge resistance. The device is RoHS3 compliant, halogen free, and Pb-free (E3). Typical applications include protection of I/O interfaces, VCC bus, and data lines in telecom, computer, industrial ICT equipment, and consumer electronics.
