Product details

1500W peak pulse power in a DO-214AB footprint

Packaged in a DO-214AB (SMC) surface-mount case, the 1.5SMC10A handles a peak pulse current of 104.8A, sufficient for suppressing surges from inductive load switching or lightning-induced transients in general-purpose circuits.

Breakdown and clamping margins

Minimum breakdown voltage is 9.5V, ensuring the device triggers before the protected circuitry sees damaging overvoltage. The 14.5V clamping ceiling limits the voltage seen by downstream components during a surge event. The single unidirectional channel is polarity-sensitive — suitable for DC rail protection where reverse polarity is not expected.

Active lifecycle and sourcing posture

The DO-214AB footprint is widely used, simplifying board layout for replacement or new designs.
