With a 47.8V standoff, this part protects 48V nominal rails — typical in automotive battery lines, PoE injectors, and 48V telecom supplies. The 53.2V breakdown minimum gives margin above the rail tolerance before the TVS starts conducting leakage current. No power line protection (unidirectional only) — the single-channel design clamps positive transients to ground; reverse polarity events require an external series diode or a separate bidirectional device. ## Active lifecycle and supply posture Tape-and-reel packaging (7-inch reel, 850 pieces per reel typical for DO-214AB) supports automated pick-and-place assembly. The AEC-Q101 traceability lot code is printed on the reel label.","metaTitle":"1.5SMC56AHR7G Zener TVS, 1500W, AEC-Q101, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC56AHR7G: 1500W peak pulse power, 47.8V standoff, 77V clamp.
