No power line protection — this is a unidirectional TVS for DC rails, not for AC mains or bidirectional signal lines. The single-channel Zener structure clamps positive transients above breakdown; reverse polarity is blocked by the diode's own forward characteristic.","metaTitle":"1.5SMC39AHM3_A/H Vishay TVS, 1.5kW, 33.3V standoff","metaDescription":"Active Vishay 1.5SMC39AHM3_A/H Zener TVS diode, 1500W peak pulse, 33.3V reverse standoff, AEC-Q101 qualified.
