Choosing a TVS with a standoff voltage below your rail (the 64.1 V reverse standoff is the rail ceiling this part leaves available headroom above) and a clamping voltage below the protected device abs-max gives you a complete protection window without over-designing the clamping element. ## Temperature grade and protection class The 150°C TJ ceiling is important for thermal design — in a worst-case clamping event the junction temperature spike depends on the peak pulse energy, the thermal resistance from junction to ambient, and the pulse width. For a 10/1000 µs surge the thermal contribution is modest, but repetitive events require checking the derating curve against the duty cycle your application imposes. ## Package and board-fit for the DO-214AB SMC The DO-214AB (SMC) is the dominant leadless SMB package for TVS diodes in the 1500W class. It mounts flush to the PCB pad with a soldered cathode tab — the tab area sets the RthJA thermal path. For a 1500W part that may absorb a single-event surge, the PCB pad geometry and the number of vias under the tab directly affect how quickly the junction cools after a clamping event. Standard reflow profile applies; no special hot-air handling is needed compared to an electrolytic or multi-pin package.","metaTitle":"Panjit 1.5SMC75CA_R1_00001 TVS Diode, 1500W 71.3V","metaDescription":"Panjit 1.5SMC75CA_R1_00001 unidirectional TVS diode, 1500W peak pulse, 71.3V breakdown, DO-214AB SMC surface mount.
