Transient protection for a 94V rail
The 1.5SMC110A-E3/9AT: This gives a protection window that keeps the downstream silicon safe from overvoltage while the TVS conducts the surge current to ground.
Package and board integration
Housed in the DO-214AB (SMC) surface-mount package, with the supplier device package designated SMCJ. The operating junction temperature range spans -65°C to +150°C, covering industrial enclosures and automotive under-hood environments where ambient temperatures can reach 105°C or more. No power line protection feature is built in — this is a standalone transient suppressor, not a filtered protector.
