Pulse power and clamping behaviour
The 1.5SMC43A-AU_R1_000A1: Rated for 1500 W peak pulse power, this part handles the energy from a 36.8 V supply line transient — for instance, a load-dump or inductive kickback — without exceeding the 59.3 V clamping ceiling. The breakdown voltage starts at 40.9 V minimum, giving a narrow guard band above the 36.8 V standoff.
AEC-Q101 and temperature range
AEC-Q101 qualification means this TVS has passed the stress tests required for automotive-grade discrete semiconductors: temperature cycling, high-temperature reverse bias, and ESD robustness.
