AEC-Q101 qualification means the part passed the automotive stress suite: 1000-hour high-temperature reverse bias (HTRB), temperature cycling, and ESD robustness per the JEDEC standard. The operating junction range of -65°C to 150°C covers under-hood ambient and engine-bay soak — the 150°C TJ ceiling gives thermal margin in a 105°C under-hood environment when the TVS is absorbing repetitive pulses. ## Peak pulse current — 3.1 A at 10/1000 µs For shorter transients (8/20 µs per IEC 61000-4-5), the peak current capability is higher — the 1500 W energy rating is the fixed budget, so a narrower pulse allows higher current before the junction temperature limit is reached. No power line protection — this is a signal-rail or DC-bus TVS, not a mains-voltage suppressor. It clamps fast transients but does not filter continuous overvoltage; a fuse or PTC ahead of the rail handles sustained overvoltage events.","metaTitle":"Vishay 1.5SMC350AHM3_A/I TVS, 1500W, 300V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC350AHM3_A/I Zener TVS diode, 1500W peak pulse power, 300V reverse standoff, AEC-Q101 qualified.
