The 1.5SMC160AS_R1_00001: The 136V reverse standoff voltage means the diode stays transparent on a nominal 120V DC bus, only conducting when the transient exceeds the 152V breakdown threshold. For a 48V or 72V telecom rail, the 136V standoff provides margin against steady-state overvoltage without nuisance clamping.
DO-214AB SMC footprint — board-fit and thermal considerations
Housed in the standard DO-214AB (SMC) surface-mount package, the part mates with a common land pattern shared across the 1.5SMC series. Unidirectional construction suits DC rails where reverse polarity protection is handled separately.
