Its 17.1V reverse standoff voltage means it sits across the line without conducting during normal operation, then fires at 19V breakdown to shunt the surge to ground. The DO-214AB (SMC) package is large enough for hand soldering with a standard iron — no hot-air rework station required for prototyping or rework. ## Clamping specs that matter for the BOM At 27.7V maximum clamping voltage, this diode holds the protected line below the typical 30V abs-max of most automotive-rated ICs and modules. The 56A peak pulse current rating (10/1000µs waveform) tells you it can absorb a substantial surge — think load-dump or alternator field decay events — without failing short. For a production BOM headed into a vehicle ECU or body controller, this certification removes the need for additional PPAP documentation from the diode alone. ## Active lifecycle and sourcing posture No minimum order threshold beyond the reel quantity; the Tape & Reel packaging suits both pick-and-place assembly and bench-level hand placement.","metaTitle":"1.5SMC20AH TVS Diode, 1500W, 17.1V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC20AH automotive TVS, 1500W peak pulse, 17.1V standoff, AEC-Q101, DO-214AB.
