The device is not rated for power-line protection — the 'Power Line Protection' field is marked 'No', so it is intended for signal, data, or DC power bus protection where the continuous voltage stays below 145 V. ## DO-214AB SMC package and temperature range Housed in the DO-214AB (SMC) surface-mount package, the 1.5SMC170CA uses the standard JEDEC footprint for this power class. The junction temperature range spans -55°C to 150°C, covering industrial control cabinets, telecom outdoor enclosures, and under-hood automotive environments where ambient heat plus self-heating from repetitive surges must stay within the 150°C absolute maximum. ## Active production — no obsolescence risk Littelfuse lists the 1.5SMC170CA as Active with no NRND or end-of-life flags. The base product number 1.5SMC covers the full series, and this bidirectional 170 V variant is a standard catalogue item, not a custom or limited-run code.","metaTitle":"Littelfuse 1.5SMC170CA TVS Diode, 1500W, 145V Standoff","metaDescription":"Littelfuse 1.5SMC170CA bidirectional Zener TVS, 1500W peak pulse, 145V reverse standoff, 234V clamp.
