The 18V reverse standoff voltage is the DC operating level where the diode draws negligible leakage; the rail sits comfortably below the 20V breakdown knee, so the TVS stays invisible until a surge arrives. ## DO-214AB SMC footprint and temperature range Housed in the DO-214AB (SMC) surface-mount package, the SMCJ18A-13-F mates with the standard SMC footprint — the same pad pattern used across the 1500W TVS family, so a BOM swap between voltage variants needs no board spin. Power line protection is not supported — this is a signal- or low-voltage-rail TVS, not a mains-side suppressor.","metaTitle":"SMCJ18A-13-F Diodes Inc TVS, 1500W, 18V Standoff, DO-214AB","metaDescription":"SMCJ18A-13-F Diodes Incorporated Zener TVS diode, 1500W peak pulse, 18V reverse standoff, 29.2V clamp.
