The P4KE91CA is a 400W bidirectional transient voltage suppression (TVS) diode from Littelfuse, designed to protect sensitive electronic equipment from electrostatic discharge (ESD), electrical fast transients (EFT), and induced lightning surges.
Key electrical specifications include a reverse standoff voltage of 77.8V, a maximum clamping voltage of 125V at a peak pulse current of 3.3A, and a typical response time of less than 1ps. The device is rated for 400W peak pulse power dissipation under a 10/1000μs waveform and features a low incremental surge resistance.
The P4KE91CA is housed in a through-hole DO-204AL (DO-41) axial leaded package, with an operating junction temperature range of -55°C to 175°C. Typical thermal resistance is 60°C/W junction-to-lead and 100°C/W junction-to-ambient. The component is lead-free (Pb-free E3) and halogen free per the datasheet, with RoHS3 and REACH unaffected compliance flags.
Ideal for use in I/O interfaces, VCC bus lines, telecom, computer, industrial ICT equipment, and consumer electronics, this TVS diode offers robust transient protection in a compact axial package.
