A soldering iron and a pair of cutters are all you need to swap it on site. ## Unidirectional Zener — one channel, one job Single unidirectional channel — the cathode band identifies the anode-to-ground orientation. No power-line protection means it is designed for signal or DC rail clamping, not AC mains. The TransZorb series is Vishay's branded TVS family, optimized for repetitive surge clamping with fast response time. General-purpose application means it fits across power supplies, I/O lines, and DC buses.","metaTitle":"1.5KE250A-E3/73 Vishay TransZorb TVS, 1500W, 214V Standoff","metaDescription":"Active Vishay 1.5KE250A-E3/73 TransZorb TVS diode, 1500W peak pulse, 214V standoff, DO-201AA axial.
