The 37.1V minimum breakdown voltage means it starts conducting just above the rail, and the 53.9V clamp limits the transient to a level most downstream DC-DC converters with 60V abs-max survive. Power line protection is not claimed, so this is a signal or DC rail TVS, not a mains surge suppressor.","metaTitle":"Panjit 1.5SMC39A_R1_00001 TVS Diode, 1500W, 33.3V Standoff","metaDescription":"Panjit 1.5SMC39A_R1_00001 Zener TVS, 1500W peak pulse, 33.3V reverse standoff, DO-214AB.
