Budget the derating path in the thermal model if the clamp is near other warm components. The DO-214AB SMC package is the standard high-power TVS footprint — the cathodic tab die-attach area drives the thermal resistance from junction to ambient. For hand-solder rework the tab requires reflow-profile attention, not just hand-iron work on the leads. ## What this part is not The spec flags Power Line Protection as No — this part is not a primary AC mains clamp. It is suited for secondary protection on DC rails, signal lines, and lower-energy transient paths. If the application is a 120/240VAC input rail you need the P6KE or 1.5KE series with appropriate surge ratings. Unidirectional only — one channel, one polarity. For bidirectional AC signal protection the 1.5SMC-C (biaxial) variant covers that use case in the same series footprint.","metaTitle":"YAGEO 1.5SMC6.8A/TR13 TVS Diode, 1500W, 6.8V","metaDescription":"YAGEO 1.5SMC6.8A/TR13 unidirectional Zener TVS, 1500W peak pulse, 6.45V breakdown, 10.5V clamping.
