The reverse standoff voltage of 17.1V and minimum breakdown of 18V make this part suitable for protecting 12V or 15V DC rails where the nominal bus stays below 17V and the TVS triggers just above that to absorb transients without clipping the supply. Housed in a DO-214AB (SMC) surface-mount package — the standard footprint for 1500W TVS diodes. Operating junction temperature range spans -55°C to 150°C, covering military and industrial thermal environments without derating concerns at the high end. For existing BOM lines, supply is managed through independent distribution; availability and pricing are confirmed at RFQ against the specific quantity and date-code requirement.","metaTitle":"Littelfuse 1.5SMC20C TVS, 1500W, 17.1V Standoff, DO-214AB","metaDescription":"Littelfuse 1.5SMC20C bidirectional Zener TVS, 1500W peak pulse, 29.09V clamp, DO-214AB.
