The 1.5SMC33CH: Rated Automotive Grade with full AEC-Q101 qualification — this is the discrete-component counterpart to AEC-Q100, covering the same reliability stress tests (temperature cycling, HTRB, H3TRB, ESD, and preconditioning) required for PPAP submission to OEMs.
The part carries AEC-Q101 qualification documentation suitable for automotive PPAP. The evidence does not list RoHS, REACH, or UL certification status — confirm these with the manufacturer or distributor at RFQ time.
For a 24 V nominal rail, this holds the transient below the typical 48 V MOSFET or IC breakdown threshold.
