The SMCJ75CAQ-13-F is a bidirectional Zener-type TVS in the DO-214AB (SMC) package, a standard 2-pin surface-mount footprint that reuses existing SMC land patterns. The package is Tape & Reel for automated pick-and-place, with a reflow profile compatible with lead-free solder processes. Rated for a 75V reverse standoff voltage, the part clamps at 121V maximum when conducting 12.4A under the 10/1000µs surge waveform, delivering 1500W peak pulse power. The 83.3V minimum breakdown guarantees the clamping threshold starts above the 75V rail.
AEC-Q101 qualification means the device has passed automotive-grade stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness, with production-part approval process (PPAP) documentation available from Diodes Incorporated. The -55°C to 150°C junction temperature range covers under-hood and cabin environments without derating at 85°C ambient. The part carries no power-line protection rating (: No), so it is intended for DC rail and signal-line clamping, not AC mains or high-energy industrial transients. For a 75V bus in an automotive ECU or industrial control board, the single bidirectional channel handles symmetrical surges without polarity concern.
