This is not a continuous power rating — it is the maximum energy the diode can absorb during a single 10 ms surge event without degrading. For context, a 143 A peak pulse current into the 10.5 V clamping ceiling confirms the device handles the current density associated with that energy window. In automotive load-dump or telecom line-surge scenarios, the 1.5 kW class is the standard choice for ECU input protection and telecom front-end rails where the transient energy budget is specified by the applicable EMC standard. ## AEC-Q101 and the automotive deployment case The AEC-Q101 qualification marks this as a automotive-grade discrete. AEC-Q101 requires the part to survive temperature cycling, humidity bias, and surge stress at the component level — not just pass a generic screening pass. The junction temperature range of -65°C to 150°C covers the full automotive thermal envelope: cold soak at temperature extremes and engine-bay ambient are both within spec. Telecom applications share the same need for a robust clamping device with a wide temperature window, which is why both markets appear in the listed applications. ## DO-214AB SMC package and surface-mount fit The DO-214AB (SMC) package is the standard high-power TVS footprint — the cathode tab carries the thermal path to the PCB pad, so the land pattern and solder-joint void content directly govern the transient energy absorption the device can actually use. Tape & Reel packing is standard for automotive high-volume assembly. The part mounts surface-mount; confirm the land pattern matches the BOM pad geometry before committing a new design.","metaTitle":"Vishay 1.5SMC6.8CAHM3_A/H TVS Diode, 1.5 kW, 5.8 V","metaDescription":"Vishay 1.5SMC6.8CAHM3_A/H bidirectional TVS diode, 1.5 kW peak pulse, AEC-Q101, DO-214AB SMC.
