The 35.5 V max clamping means a downstream 40 V-rated DC-DC converter or sensor IC sees a peak well inside its abs-max rating. The 42.2 A peak pulse current is the current the diode can sink during the 10/1000 µs surge — match this to the expected surge impedance of the harness or the upstream fuse's I²t curve. The DO-214AB (SMC) package is the standard footprint for a 1500 W TVS — the copper pad area on the PCB sets the thermal impedance for repetitive pulses. The -55 °C to 150 °C junction range covers the full automotive temperature envelope with margin for self-heating during a surge. ## Active production and sourcing posture The base product number SMCJ22 covers the family — the full suffix includes the bidirectional (CA) and automotive (Q) variants.","metaTitle":"SMCJ22CAQ-13-F Diodes Inc TVS, 1500W, Bidirectional","metaDescription":"SMCJ22CAQ-13-F Zener TVS diode, 1500W peak pulse power, 22V standoff, bidirectional, AEC-Q101 qualified.
