That 246V ceiling tells you what the downstream silicon sees during a surge — a 48V power supply on the same rail needs a 250V-rated input stage to survive. Housed in the DO-214AB (SMC) package, also listed as the supplier device package SMCJ. This is the standard footprint for 1500W TVS diodes in this voltage class — the same pad layout accepts the 1.5SMC series across the full voltage range, so a single copper pattern serves the whole BOM family. Surface-mount only; no through-hole variant exists. The 150°C TJ rating means the die temperature can climb during a pulse train without immediate failure, but the long-term reliability at elevated ambient follows the standard Arrhenius derating.","metaTitle":"Littelfuse 1.5SMC180A TVS Diode, 154V Standoff, DO-214AB","metaDescription":"Littelfuse 1.5SMC180A Zener TVS diode, 1500W peak pulse, 154V reverse standoff, 246V clamping.
