AEC-Q101 qualification — the automotive reliability gate
The 1.5SMC24CA-Q: Part of the 1.5SMC-Q series, this device is AEC-Q101 qualified — the automotive-grade stress test suite that covers temperature cycling, high-temperature reverse bias, and ESD robustness.
1500W peak pulse — what the rating means for your circuit
The 20.5V reverse standoff voltage means the device stays transparent below that rail voltage; it only starts conducting when the line exceeds 22.8V breakdown, so it does not load the signal during normal operation.
DO-214AB footprint — board integration
Housed in the standard DO-214AB (SMC) surface-mount package, the part reflows on a standard lead-free profile and shares the same land pattern as other SMC-packaged TVS diodes. Surface-mount assembly keeps the pick-and-place cycle time low; the package is large enough for hand-soldering with a fine-tip iron if you are prototyping or doing rework.
