20KPA172A Description

Short technical summary and product information.

The 20KPA172A is a unidirectional transient voltage suppressor (TVS) diode from Littelfuse Inc., part of the 20KPA series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. Key specifications include a reverse standoff voltage of 172V, a clamping voltage of 277V, and a peak pulse power dissipation of 20000W (20kW) under a 10/1000μs waveform. The device features a fast response time typically less than 1.0ps from 0V to breakdown voltage. It can handle a peak pulse current of 72.9A. The operating junction temperature range is -55°C to 175°C. The diode is packaged in a P600 axial package (through-hole mounting) and is RoHS compliant and halogen free. Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The device offers low incremental surge resistance and typical reverse leakage current less than 2μA for breakdown voltages above 49V.
