The reverse standoff of 64.1 V sets the normal working voltage; once the line exceeds the 71.3 V minimum breakdown threshold the device clamps, with the peak clamping voltage held at 103 V across the 15 A pulse. For a 12 V rail in an automotive environment, this part sits comfortably above the nominal bus with margin — transients from inductive kick or load dump will hit the 71.3 V breakdown before the clamping action holds the rail at 103 V, protecting any downstream IC below that level. The CA suffix confirms unidirectional polarity; bidirectional units in this series carry a BA suffix. ## Automotive grade and thermal margin AEC-Q101 qualification means the die and packaging have passed automotive environmental stress — temperature cycling, humidity bias, and surge life testing per the standard. Junction temperature rating is -55 °C to 150 °C, which gives headroom in engine-compartment and body-control module deployments where ambient can reach 125 °C underhood. ## SMC package and pick-place reality The DO-214AB SMC is a standard JEDEC footprint — no exotic coplanarity issues, compatible with the standard SnPb or lead-free reflow profiles used in most assembly houses. Tape-and-reel packaging keeps it compatible with high-volume reel-fed placement lines.","metaTitle":"1.5SMC75CAHR7G TVS Diode, 1.5kW, 103V Clamping","metaDescription":"Taiwan Semiconductor 1.5SMC75CAHR7G bidirectional TVS diode, 1500W peak pulse, AEC-Q101 qualified, DO-214AB.
