The 85.5 V reverse standoff voltage (working voltage) means the TVS draws negligible leakage below that rail. The 90 V minimum breakdown guarantees the clamping starts above the normal operating voltage. The 143.85 V maximum clamp at 11.1 A peak pulse current sets the voltage the downstream ICs must survive. ## Board-fit and package note DO-214AB (SMC) is the larger of the standard SMC package variants — the same footprint as the SMCJ suffix in the supplier device package field. The 1500 W rating requires the larger body to dissipate the pulse energy; a DO-214AA (SMA) package in the same series would be limited to 600 W. The cathode band on the body marks the unidirectional orientation — reverse the part and the TVS acts as a forward-biased diode, clamping at about 1 V instead of 143 V, which destroys the protection function. ## Lifecycle reality — obsolete with no successor on record Littelfuse has marked the 1.5SMC100 as obsolete.","metaTitle":"Littelfuse 1.5SMC100 Zener TVS, 1500W, DO-214AB","metaDescription":"Obsolete Littelfuse 1.5SMC100 Zener TVS diode, 1500W peak pulse, 85.5V standoff, DO-214AB.
