1500 W peak pulse power — 20.5 V standoff rail
The 1.5SMC24A_R1_00001: It clamps transients at 33.2 V maximum, shunting up to 45 A of peak pulse current away from the protected circuit.
DO-214AB SMC — board-fit and temperature range
The SMC footprint is a standard JEDEC outline — the copper pad area under the cathode tab sets the thermal resistance, so the board layout should match the recommended land pattern for full 1500 W dissipation.
