The 78 V standoff voltage is the maximum DC or AC peak the TVS will not conduct at, so it sits across the rail without leakage until a transient exceeds the breakdown threshold. ## DO-214AB SMC package and board integration The operating temperature range spans -55 °C to 150 °C, covering the full industrial and automotive ambient envelope.","metaTitle":"SMCJ78A-13 Diodes Inc TVS, 78V Standoff, 1500W, DO-214AB","metaDescription":"SMCJ78A-13 TVS diode, 78V reverse standoff, 126V clamp, 1500W peak pulse, DO-214AB SMC.
