The reverse standoff voltage is 51.7 V typ, with breakdown guaranteed between 64.6 V min. If your rail sits at 48 V or 52 V nominal, this part gives you a guard band before the TVS starts conducting leakage current. ## Temperature range and environment fit The SQ-MELF (B) package is a ceramic-like surface-mount body that handles thermal cycling better than a plastic SMC. ## Active production — no end-of-life watch needed That means you can BOM it without planning a last-time-buy or a qualification cycle for a replacement. The base product number is 1N6126, so if you see other suffix variants (e.g., leaded or different screening levels), the core die and breakdown voltage are the same — only the package or test flow changes.","metaTitle":"1N6126AUS Zener TVS Diode – 500 W, 51.7 V Standoff, SQ-MELF","metaDescription":"1N6126AUS from Microchip Technology: 500 W peak pulse power, 51.7 V reverse standoff, 97.1 V clamp.
