Rated for automotive applications, it carries AEC-Q101 qualification, meaning it has passed the reliability stress tests and temperature cycling required for under-hood and chassis-domain electronics. This gives a tight clamping ratio for a 1.5kW device, important for protecting downstream 48V bus or 12V automotive rails from load-dump and inductive kickback transients. ## Automotive-grade transient protection Its AEC-Q101 Grade 0 temperature range (-65°C to 150°C) suits it for engine-bay and underhood environments where ambient temperatures exceed 105°C. The tape-and-reel packaging is standard for automated pick-and-place assembly. The device is surface-mount, and the DO-214AB (SMC) body is compatible with reflow soldering profiles typical for lead-free assembly.","metaTitle":"1.5SMC51AHM3_A/H Vishay TVS Zener, 1.5kW, AEC-Q101, DO-214AB","metaDescription":"Vishay 1.5SMC51AHM3_A/H automotive TVS Zener diode, 1500W peak pulse, 70.1V clamp, AEC-Q101 qualified.
