Product details

Key ratings and what they mean for the BOM

The 1.5SMC220C: A downstream component rated below 344 V sees the full clamping voltage across its terminals during the event.

DO-214AB (SMCJ) surface-mount package — the same footprint as standard SMC diodes. The cathode band identifies the anode for unidirectional variants; on this bidirectional part orientation is irrelevant, which simplifies pick-and-place setup. No power line protection — this is a signal or low-power rail TVS, not a mains surge suppressor.
