30KPA45A Description

Short technical summary and product information.

The 30KPA45A is a unidirectional Zener TVS diode from Littelfuse, part of the 30KPA Series. It features a reverse standoff voltage of 45V and a clamping voltage of 77.4V. With a peak pulse power rating of 30kW (10/1000μs waveform) and a peak pulse current of 391.5A, it provides robust protection against voltage transients. The device exhibits a fast response time of less than 1ps, making it suitable for protecting sensitive electronics. It is designed for general purpose applications such as I/O interfaces, VCC bus, and other circuits in telecom, computer, industrial, and consumer electronics. The 30KPA45A is housed in a P600 axial through-hole package and operates over a junction temperature range of -55°C to 175°C. Steady state power dissipation is 8W on infinite heat sink. The component is halogen free and RoHS compliant per datasheet claims.
