For a 256V DC bus — common in three-phase rectified industrial supplies — the 434.7V clamp keeps transients below the typical 600V MOSFET rating. ## Package and temperature grade The single bidirectional channel replaces two unidirectional devices in back-to-back configuration, saving board area.","metaTitle":"Littelfuse 1.5SMC300C TVS Diode, 270V Breakdown, DO-214AB","metaDescription":"Littelfuse 1.5SMC300C bidirectional Zener TVS diode, 1500W peak pulse, 270V min breakdown, 256V standoff.
