The 1.5SMC47A R7G: With 1500 W (1.5 kW) peak pulse power, this diode absorbs surge energy from inductive load switching, lightning-induced transients, or ESD events without failing short — the 24 A peak current rating confirms it can handle a sustained surge into the 64.8 V clamp.
Confirm the standoff voltage and clamping requirements before substituting.
