The reverse standoff voltage is 78 V, so it sits across a 78 V nominal rail and stays transparent until the transient exceeds the minimum breakdown voltage of 86.7 V. Below that threshold, the diode draws negligible leakage; above it, the avalanche action shunts the surge to ground. ## Automotive AEC-Q101 — what the grade certifies This part belongs to the Automotive, AEC-Q101, SMCJ series. Housed in a DO-214AB (SMC) surface-mount package, the SMCJ78CAQ-13-F is a standard footprint for high-power TVS diodes. The SMC package's large copper tab on the cathode side (for unidirectional versions) or the body itself (bidirectional) conducts heat into the PCB copper plane — the 1500 W rating assumes a low-thermal-resistance board layout with adequate pad area. Supplied on Tape & Reel, it is compatible with automated pick-and-place assembly. The bidirectional configuration (single channel) means the same device clamps positive and negative transients, so orientation on the board does not matter — one part number covers both polarities.","metaTitle":"SMCJ78CAQ-13-F TVS Diode, 1500W, Bidirectional, AEC-Q101","metaDescription":"Diodes Inc SMCJ78CAQ-13-F Zener TVS, 1500W peak pulse, 78V standoff, bidirectional, AEC-Q101 automotive grade.
