At 25.6A peak pulse current, the voltage clamps at 59.3V max, which is the ceiling the downstream silicon sees. Reverse standoff of 36.8V means the part sits on a 24V or 36V rail without conducting in normal operation — it only starts to avalanche when the line spikes above that threshold. The breakdown minimum is 40.9V, so there is a 4.1V window between standoff and guaranteed breakdown where leakage is negligible. ## AEC-Q101 — why this matters for more than just cars AEC-Q101 qualification means this part passed the automotive stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness. No hot-air station needed for a swap. ## Active lifecycle — no rush on the BOM line The part is from the 1.5SMC-Q series, which is the AEC-Q101-graded sibling of the standard 1.5SMC line. If your BOM already uses the non-Q version, the footprint and electrical specs are the same — the Q suffix adds the automotive paperwork for PPAP traceability.","metaTitle":"Bourns 1.5SMC43CA-Q TVS Diode, 1500W, AEC-Q101, DO-214AB","metaDescription":"Bourns 1.5SMC43CA-Q bidirectional Zener TVS, 1500W peak pulse, 36.8V standoff, 59.3V clamp.
