Unidirectional — one channel, cathode-band polarity marked on the DO-201AA axial body; the anode connects to ground, cathode to the protected rail. Through-hole DO-201AA / DO-27 package with a -55°C to 175°C operating junction range — wide thermal margin suits PSU output stages, industrial control boards, and telecom line cards where ambient heat is high.","metaTitle":"1.5KE33A-E3/51 Vishay TransZorb TVS, 1500W, 28.2V Standoff","metaDescription":"Vishay 1.5KE33A-E3/51 TransZorb TVS diode, 1500W peak pulse, 28.2V reverse standoff, DO-201AA axial.
