The 1.5KE24A B0G: Reverse standoff voltage is 20.5 V, meaning the line it protects can run at 20.5 V DC nominal without the TVS conducting leakage. Breakdown occurs at 22.8 V min, and clamping is held to 33.2 V max at the 47 A peak pulse current — tight enough to keep downstream 24 V-rated silicon inside its safe operating area. No power-line protection (no bidirectional topology), so it is a straight unipolar clamp for DC rails.
