At the 18.8 V reverse standoff voltage (VRWM), the diode is effectively off and draws negligible leakage. When a transient exceeds the 20.9 V minimum breakdown voltage, it clamps the surge to a maximum of 30.6 V at the rated 51 A peak pulse current (Ipp). The margin between the protected rail's normal operating voltage and the 18.8 V standoff is the design headroom. ## Package and board-fit for the DO-214AB footprint The supplier device package is DO-214AB (SMC), so the land pattern is the same for any sibling in the family — a BOM change between voltage variants does not require a board spin. The wide Tj window means the leakage and clamping characteristics stay within spec across the full temperature sweep of a typical power supply or I/O line. ## Active production — sourcing posture for this TVS The Tape & Reel packaging (R7G suffix) suits automated pick-and-place assembly.","metaTitle":"1.5SMC22A R7G TVS Diode, 1500W, 18.8V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC22A R7G Zener TVS, 1500W peak pulse, 18.8V reverse standoff, 30.6V clamp.
