Operating junction temperature runs from -50°C to 150°C, so the part handles the thermal headroom of a protected power-supply or IO line in an enclosed panel without derating concerns up to the rated pulse. ## Package and board-level fit The DO-214AB SMC package is the standard SMB footprint — pin-compatible across most 1500W unidirectional TVS families from multiple brands, so swapping in a second-source alternative at the BOM stage usually requires only a footprint confirmation. Surface-mount termination; the package ships in strip form per the listing. General-purpose application rating means it is suited for IO bus protection, power supply clamping, and rail-to-rail transient suppression — not power-line mains protection, which requires a different peak pulse and repetition duty rating. ## Active status and sourcing posture marks the part as Active.","metaTitle":"1.5SMCJ70A Zener TVS Diode, 70V Standoff, DO-214AB","metaDescription":"Diotec Semiconductor 1.5SMCJ70A unidirectional Zener TVS, 1500W peak pulse, 70V standoff, 113V clamping.
