The bidirectional channel protects both polarities from a single device, reducing component count on the PCB. The part carries the TransZorb® trademark and is part of Vishay's automotive-grade 1.5SMC family.","metaTitle":"1.5SMC51CAHE3/9AT Vishay TVS, 1500W, 43.6V Standoff","metaDescription":"Active Vishay 1.5SMC51CAHE3/9AT bidirectional TVS diode, 1500W peak pulse, 43.6V reverse standoff, AEC-Q101 qualified.
