The 1.5SMC170A-M3/57T: The 234 V clamp ceiling means a 145 V nominal rail gets shunted to a safe level during a transient, protecting downstream components rated for 250 V or less.
Vishay lists the 1.5SMC170A-M3/57T as Active.
It is supplied in a DO-214AB (SMC) surface-mount package, on tape and reel. The supplier device package is also listed as DO-214AB (SMCJ).
