20KPA32A

The Littelfuse 20KPA32A is a unidirectional Zener TVS diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It features a 32V reverse standoff voltage and a maximum clamping voltage of 54.3V, capable of handling a peak pulse current of 372A. With a peak pulse power dissipation of 20kW (10/1000μs waveform), this device offers robust protection for I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer applications. The 20KPA32A is housed in a through-hole P600 axial package with matte tin plated leads, supporting an operating junction temperature range of -55°C to 175°C. It also provides a steady state power dissipation of 8.0W and a peak forward surge current rating of 400A. The diode is RoHS compliant and lead-free, with a fast response time of typically less than 1.0ps. This component is ideal for general-purpose circuit protection where high surge capability and reliable performance are required.
