The 1N6472US: When a 15V rail sees a spike, the diode breaks down at 16.4V min and hard-clamps at 26.5V max, shunting up to 322A (8/20µs) to ground. For a repair bench, that 1500W rating means this part survives the kind of surge that kills smaller TVS diodes; the scorch mark tells you the upstream rail took the hit, not the diode.
Microchip lists the 1N6472US as Active — no end-of-life notice, no successor announced.
Rated at 1500W for a 10/1000µs waveform. That's the surge it can clamp without damage — a common benchmark for TVS diodes in this package class.
