The 70.1 V reverse standoff is the working voltage the diode sustains without conduction, so the protected rail should sit below that level in normal operation. At 1500 W peak pulse the 1.5SMC series handles short-duration surges common in supply and data-line environments — the 10/1000 µs rating is the standard 1.5 kW lightning-surge pulse per IEC 61000-4-5, not a continuous dissipation figure. ## Sourcing the obsolete part Independent surplus and excess-inventory channels are the sourcing path; lot traceability and genuine-part verification are the primary vetting steps for a TVS in this power class. A BOM line running this part should flag it for a cross-reference review before the board reworks or a new build is committed.","metaTitle":"Littelfuse 1.5SMC82AT3G TVS Diode, 113V Clamping, DO-214AB","metaDescription":"Littelfuse 1.5SMC82AT3G Zener TVS, 70.1V standoff, 113V clamping @ 13.3A, 1500W peak pulse, DO-214AB SMC.
