The Littelfuse 15KPA43A is a unidirectional Zener TVS diode designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 43V, a minimum breakdown voltage of 47.8V, and a clamping voltage of 69.8V at a peak pulse current of 216.3A. With a peak pulse power dissipation of 15kW (10/1000µs waveform), it offers robust protection for I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer applications.
The device is packaged in a P600 axial through-hole package, suitable for high-reliability soldering. It operates over a junction temperature range of -55°C to 175°C and has a typical reverse leakage current of less than 2µA. The response time is typically less than 1ps from 0V to breakdown voltage, ensuring fast clamping. The 15KPA43A is RoHS, halogen-free, and Pb-free compliant, with UL recognition (file E230531). It also meets IEC 61000-4-2 ESD requirements (30kV air/contact) and IEC 61000-4-4 EFT protection.
The reverse standoff voltage is 43V.
The minimum breakdown voltage is 47.8V.
