1500 W peak pulse — clamping a 30.8 V rail
The 1.5SMC36A-E3/57T: Its 1500 W peak pulse power rating (10/1000 µs waveform) means it can absorb a 30.1 A surge before the clamping voltage hits 49.9 V — enough headroom for a 24 V or 28 V bus that sees occasional load-dump or inductive kickback. The 150°C maximum junction temperature lets it sit on a warm board without derating the pulse capability, though repetitive surges should be checked against the device's thermal impedance.
DO-214AB footprint and board integration
The 1500 W pulse rating in this package requires adequate copper area on the PCB to spread heat during repetitive events — a solid ground-plane connection under the cathode tab is the standard practice.
