5KP26A Description

Short technical summary and product information.

The 5KP26A is a 5kW unidirectional Zener TVS diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients caused by lightning and other transient events. It is part of the 5KP series, offering a peak pulse power dissipation of 5kW (10/1000μs waveform) with a reverse standoff voltage of 26V.

Key electrical specifications include a maximum clamping voltage of 42.1V at 121.1A peak pulse current, and a fast response time typically less than 1.0ps. The device features a glass passivated junction in a P600 axial package, rated for operating junction temperatures from -55°C to 175°C. It supports a peak forward surge current of 400A (8.3ms) and has a steady-state power dissipation of 8.0W.

This TVS diode is suitable for general purpose applications, including protection of I/O interfaces, VCC buses, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The through-hole mounting and axial leaded package allow for easy integration into PCB designs. The device is RoHS compliant and halogen free per the datasheet.
