The 1.5SMC12: At the rated 91 A peak pulse current, the clamping voltage holds at 17.54 V max — this is the voltage the downstream circuitry sees during a surge event. The 10.2 V reverse standoff voltage means the diode stays transparent on a 10 V rail; it starts conducting at 10.8 V minimum breakdown.
Littelfuse has marked the 1.5SMC12 as Obsolete. No pin-compatible direct replacement from Littelfuse is documented.
Housed in a DO-214AB (SMC) surface-mount package, also referred to as SMCJ.
The 10.2 V standoff and 10.8 V breakdown thresholds make it a fit for protecting 10 V supply lines in general-purpose circuit protection applications.
