The clamping voltage ceiling of 15.9 V is what the downstream IC sees at the peak of the event, so the downstream absolute-maximum rating must tolerate that let-through level. ## DO-214AB SMC package and thermal junction window The DO-214AB (SMC) package is the industry-standard surface-mount TVS footprint — compatible with reflow assembly without special profiles and mates with standard 3D CAD libraries. Soldering the SMC tab directly to the PCB plane is the primary thermal path — the datasheet thermal resistance figure governs the junction temperature rise under repeated transients, not just the steady-state current. Power line protection is listed as No, confirming this is a signal-line or local rail clamp rather than a bus-bar suppressor. ## General-purpose signal-line clamping context Rated for general-purpose applications and surface-mounted, this part protects low-current rails and signal lines rather than power rails — the 94.3 A peak pulse figure is a short-duration spec, not a continuous current rating. The single bidirectional channel means it is a unidirectional TVS oriented with cathode to the rail — on a positive-going transient the cathode clamps to ground through the TVS, leaving the anode tied to ground. Validated by the breakdown minimum of 9.4 V and the clamping maximum of 15.9 V; the clamping ratio of roughly 1.9× the standoff voltage is typical for this Zener-based TVS family.","metaTitle":"1.5SMCJ8.5C TVS Diode, 1500 W Peak, 15.9 V Clamp","metaDescription":"Diotec 1.5SMCJ8.5C unidirectional TVS diode, 8.5 V standoff, 9.4 V breakdown, 1500 W peak pulse rating in DO-214AB SMC package.
