Product details

1500 W peak pulse — clamping voltage and the protection window

The 1.5SMC39CA R7G: The 37.05 V minimum breakdown voltage sits between standoff and clamp, defining the avalanche threshold.

DO-214AB surface-mount — board integration and thermal path

The package footprint matches standard SMC solder pads, and the 1500 W rating assumes the PCB copper area provides adequate heatsinking per the datasheet layout recommendation.

Taiwan Semiconductor Corporation lists the 1.5SMC39CA R7G as Active.
