The Littelfuse 20KPA104A-B TVS Hi-Power Diode Axial with ESD Suppressors / TVS Diodes is a diode designed for the protection of high-voltage and high-power applications. This product is ideal for protecting against electrostatic discharge (ESD), voltage transients, and voltage surges, and is suitable for use in automation, communications, IT, lighting, and transportation applications. The 20KPA104A-B has a reverse Standoff Voltage of 20V and a Clamping Voltage of 39V. It features an Ipp (on-state peak pulse current) rating of 100A per any 10/1000µs pulse (not exceeding 1% duty cycle) and a peak pulse power of 12.5kW (10/1000µs) to ensure superior protection and reliable operation. Additionally, its fast response time (<1ps) ensures protection against fast rise rate transients.
