Automotive-grade 1500 W TVS in a DO-214AB SMC package
The SMCJ7.5AQ-13-F: It carries AEC-Q101 automotive qualification, meaning it is screened for reliability under the temperature and stress conditions typical of under-hood and chassis-mounted electronics.
What the key ratings mean for your BOM
The 8.33 V minimum breakdown voltage and 12.9 V maximum clamping voltage define the protection window: the rail must stay below 8.33 V during normal operation, and the clamp activates before the voltage exceeds 12.9 V, which is safe for most 12 V automotive-rated ICs. Operating temperature range from -55°C to 150°C covers the full automotive thermal profile, including cold crank at -40°C and under-hood ambient near 125°C.
Housed in a DO-214AB (SMC) surface-mount package, the SMCJ7.5AQ-13-F mounts on standard PCB footprints with a 0.050-inch (1.27 mm) pin pitch and a body size that suits medium-power TVS applications. The SMC package provides a larger copper pad area than the smaller SMA/SMB variants, improving thermal dissipation during repetitive surge events — important for automotive environments where ambient temperatures are high.
