For a telecom 48 V rail, the 45.4 V standoff gives comfortable headroom below the minimum breakdown — the part is off at normal operating voltage and turns on only for the transient. ## Automotive grade and temperature range AEC-Q101 qualification means the part passed the automotive discrete semiconductor stress battery — temperature cycling, humidity, and surge current. The junction operating range of -55°C to 150°C covers the full automotive thermal band. For engine-compartment or body-control modules that see prolonged 125°C ambient, the 150°C Tj ceiling still leaves derating margin at the package level. ## Package and assembly notes The DO-214AB SMC is the larger SMC variant — it is not the same foot print as a DO-214AA or DO-214AC SMA. Verify the pad layout on the board landing pattern before committing a BOM quantity. Shipped on tape and reel per; confirm reel orientation matches the pick-and-place feeder configuration. ## Sourcing posture and lifecycle Listed Active by Taiwan Semiconductor Corporation.","metaTitle":"1.5SMC56H 1.5kW Zener TVS, AEC-Q101, DO-214AB","metaDescription":"1.5SMC56H is an AEC-Q101 qualified Zener TVS in DO-214AB SMC. 1.5 kW peak pulse, 80.5 V clamping, 45.4 V standoff.
