The 1.5SMC33AS_R1_00001: The breakdown starts at 31.4 V minimum, and the clamp holds at 45.7 V maximum while shunting 33 A — that 45.7 V ceiling is the voltage the protected IC sees during the surge. For shorter transients (e.g. 8/20 µs), the device can handle a higher peak current — the datasheet derating curve governs the actual margin.
