The DO-214AB (SMC) footprint is shared across the 1.5SMC series, so a parametric cross to a higher-voltage or higher-power sibling in the same package is possible, but no pin-compatible drop-in replacement is documented by the manufacturer. ## Board-fit and temperature envelope Surface-mount DO-214AB (SMC) package — the same footprint as the SMCJ industry standard. The junction operates from -55 °C to 150 °C, covering industrial and automotive under-hood ambient ranges without derating the peak pulse power at the low end.","metaTitle":"1.5SMC11 Littelfuse TVS Diode, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC11 Zener TVS diode, 1500W peak pulse, 9.4V standoff, DO-214AB.
