This 70.1 V clamp ceiling is the hard limit — downstream circuitry must survive that peak without damage. ## Package and thermal envelope The supplier device package is DO-214AB (SMC), identical to the case code. No power line protection is built in — this is a signal-rail or low-voltage DC bus protector, not a mains-side MOV replacement. ## Active lifecycle and telecom fit The application designation is Telecom — the 43.6 V standoff aligns with 48 V telecom bus protection (typically ±20% tolerance), where the TVS clamps lightning-induced or power-cross surges before they reach the line card. The 1500 W rating covers the primary protector's let-through energy on a typical intra-building run.","metaTitle":"1.5SMC51A V7G TVS Diode, 1500W, 43.6V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC51A V7G Zener TVS, 1500W peak pulse, 43.6V standoff, 70.1V clamp, DO-214AB SMC.
