The 33.3 V standoff means this diode will not conduct at the rail voltage — it sits across the line and only starts to avalanche when the transient exceeds the minimum breakdown voltage of 37.1 V. The 53.9 V clamp is the ceiling: downstream components rated for at least that peak voltage survive the surge. The bidirectional channel means one part covers both polarities — no need to orient the diode on the board, which simplifies pick-and-place and reduces BOM line count. The copper pad area under the cathode tab sets the thermal resistance — for a 1500 W pulse, the board's copper plane acts as the heat sink.","metaTitle":"Vishay 1.5SMC39CA-M3/57T TVS, 1500W, 33.3V Standoff","metaDescription":"Vishay 1.5SMC39CA-M3/57T bidirectional TVS diode, 1500W peak pulse, 33.3V standoff, DO-214AB.
