Matching the rail voltage — 110 V reverse standoff
The 7.7 A peak pulse current at the 196 V clamping voltage gives the design margin for a worst-case transient.
Unidirectional — one channel, polarity matters
This is a single-channel unidirectional TVS. It protects one DC rail with the cathode tied to the positive side. For AC lines or bidirectional protection, you would need two devices back-to-back or a bidirectional part — a common BOM check when the circuit sees both positive and negative transients.
Package and mounting — DO-214AB (SMC)
Housed in a DO-214AB (SMC) surface-mount package, this TVS reflows with standard lead-free profiles.
Lifecycle — active, no end-of-life pressure
For a storeroom planner, this means the part is still a standard catalog item — no need to stockpile beyond normal reorder levels.
