20KPA52A Description

Short technical summary and product information.

The 20KPA52A is a unidirectional TVS diode from Littelfuse designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It features a reverse standoff voltage of 52V and a maximum clamping voltage of 85.8V at a peak pulse current of 235.4A (10/1000μs waveform). The device can dissipate 20kW of peak pulse power and has a steady state power dissipation of 8.0W on an infinite heatsink.

 

This TVS diode offers fast response time of less than 1.0ps from 0V to breakdown voltage minimum. It is housed in a P600 axial leaded package with through-hole mounting and matte tin lead-free plating. The operating junction temperature range is -55°C to 175°C.

 

The 20KPA52A is suitable for general purpose protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronic applications. It is RoHS compliant and halogen free.
