AEC-Q101 qualification and deployment context
The SMCJ24AQ-13-F: Rated AEC-Q101, this Zener TVS is qualified for automotive-grade stress screening and PPAP documentation — the OEM auditor expects this certification for any protection device on the 12 V bus in an underhood ECU.
Clamping performance and surge rating
Reverse standoff voltage is 24 V, breakdown minimum 26.7 V — the device remains transparent below 24 V and clamps hard once the transient exceeds the breakdown knee.
Housed in the DO-214AB (SMC) package, surface-mount, with a single unidirectional channel — the cathode band on the package body matches the PCB silkscreen polarity mark; reverse insertion bypasses the protection entirely.
