What the 1500W pulse rating means on the bench
The 1.5KE75CA R0G: On a board with a 48V supply, this diode clamps a surge to 103V, well below the typical 200V rating of downstream electrolytics. The through-hole DO-201AA / DO-27 axial package is a standard footprint — the same hole pattern as the 1N6267 and similar 1500W TVS parts, so a board already laid out for a 1.5KE series diode accepts this drop-in.
