P4KE10C

The P4KE10C is a bidirectional Zener TVS diode from Littelfuse Inc., part of the P4KE series designed for transient voltage suppression. It offers 400W peak pulse power dissipation at 10/1000μs waveform, protecting sensitive electronic equipment from EFTs, ESD, and induced lightning transients. Key electrical specifications include an 8.55V reverse standoff voltage, a clamping voltage of 15.23V at 28.3A peak pulse current, and a fast response time of less than 1.0ps from 0V to VBR min. The device meets IEC 61000-4-2 ESD protection standards with 30kV air and 30kV contact discharge capability. It operates over a junction temperature range of -55°C to 175°C and has thermal resistance of 100°C/W junction-to-ambient and 60°C/W junction-to-lead. The P4KE10C is housed in a DO-204AL (DO-41) axial leaded through-hole package, making it suitable for through-hole mounting on PCBs. Typical applications include I/O interface protection, VCC bus protection in telecom, computer, industrial ICT, and consumer electronics. The device is lead-free (Pb-free E3) and halogen-free, with RoHS compliance claimed but unverified.
