That clamping voltage is what the downstream silicon sees; if the DC-DC converter's abs-max input is 75V, this part keeps the transient below that threshold. ## Automotive-grade — AEC-Q101 and the temperature envelope AEC-Q101 qualification means this diode passed the automotive stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness. No orientation guesswork on the pick-and-place reel. ## Active — no end-of-life watch needed This part carries an Active lifecycle status from Vishay. No PCN, no last-time-buy window, no successor to track. It is a current-production catalog item, so the BOM line does not need a second-source hedge for obsolescence reasons. Sourced and quoted to order against RFQ through independent distribution.","metaTitle":"Vishay 1.5SMC51AHM3/H TVS, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC51AHM3/H Zener TVS diode, 1500W peak pulse, 43.6V standoff, AEC-Q101, DO-214AB.
