It is a single bidirectional channel — one device clamps both polarities, saving a diode bridge and a second part on the rail.","metaTitle":"1.5KE27CA-E3/73 Vishay TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5KE27CA-E3/73 TransZorb TVS diode, 1500W peak pulse power, 23.1V standoff, bidirectional, DO-201AA axial.
