Automotive-grade TVS for 12V rail protection
The 1.5SMC15A-Q: It clamps transients on a 12.8 V nominal rail to 21.2 V at a peak pulse current of 71.7 A (10/1000 µs waveform), absorbing 1500 W of surge energy. The 12.8 V reverse standoff voltage suits it for 12 V battery systems where the nominal bus sits below 13 V; the 14.3 V minimum breakdown ensures the device does not conduct during normal operation.
Package and board-fit: DO-214AB (SMC)
Housed in a DO-214AB (SMC) surface-mount package, the 1.5SMC15A-Q mates with the standard SMC footprint. The package is compatible with reflow profiles typical for lead-free soldering; MSL rating is not explicitly listed but the 150°C storage limit implies a moisture sensitivity level of 1 or 2 for standard SMC packages.
Sourcing and compliance
AEC-Q101 certification covers the automotive reliability screening (temperature cycling, ESD, preconditioning).
