Product details

The 1.5SMC22C: For a BOM line that depends on this specific TVS, the procurement path is the independent surplus and broker market. Availability is lot-specific and confirmed at quote time — no standing inventory is held against this listing.

Package and board-fit — DO-214AB (SMC) footprint

The cathode band is marked on the body; for a bidirectional device the banding convention is manufacturer-specific, so confirm the orientation on the reel label before placement. The tape-and-reel packaging (TR) is compatible with automated pick-and-place assembly.

Frequently asked questions

What is the closest pin-compatible alternative to the 1.5SMC22C?

No pin-compatible successor is recorded from Littelfuse. A parametric search across other TVS families in the same package is the practical path — the board layout does not change if the footprint matches.
