The 19V minimum breakdown voltage sets the guard band — a 17.1V rail with 5% regulation rides at 16.2V, leaving nearly 3V of margin before the TVS starts clamping. ## Package and thermal footprint One channel, one placement on the board, one BOM line for both polarities. ## Lifecycle and procurement posture The 1.5SMC series is a mature, widely second-sourced platform; the DO-214AB package and 1500W rating are industry-standard, so alternate sources exist if supply tightens.","metaTitle":"1.5SMC20CA R7G TVS Diode, 1500W, 17.1V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC20CA R7G bidirectional Zener TVS, 1500W peak pulse power, 27.7V clamping at 56A, DO-214AB.
