The 1.5SMC22: Reverse standoff voltage is 18.8 V; breakdown occurs at a minimum of 19.8 V.
Housed in a DO-214AB (SMCJ) surface-mount package, supplied on Tape & Reel for automated pick-and-place assembly. The SMC footprint is larger than the SMA/SMB siblings, providing a lower thermal resistance path to the PCB copper for the 1500 W pulse rating.
No official successor or pin-compatible replacement is recorded in the manufacturer's lifecycle data.
