The single unidirectional channel means polarity must be observed in layout: the cathode band on the package marks the protected rail side, and the anode connects to ground. Target applications include automotive and telecom equipment, where the 185 V standoff and 1500 W pulse rating cover transient protection for 185 V nominal DC buses or AC rectified lines.","metaTitle":"Vishay 1.5SMC220AHM3_A/I TVS, 1500W, 185V Standoff, DO-214AB","metaDescription":"Active Vishay 1.5SMC220AHM3_A/I Zener TVS diode, 1500W peak pulse, 185V reverse standoff, AEC-Q101 qualified.
