The SQ-MELF B package (surface-mount, cylindrical body) is a hermetic glass seal — the same construction used in military and aerospace transient suppressors. The -55°C to 175°C junction range means this part can sit on a hot avionics bus or near an engine bay without derating at the cold end. ## Breakdown, clamping, and standoff — the protection window The reverse standoff voltage is 114V; the device starts conducting at 142.5V minimum breakdown, and hard-clamps at 206.3V maximum. For a 114V nominal rail, this leaves a 28.5V margin before avalanche and a 92.3V ceiling above the rail — a tight window that keeps downstream semiconductors inside their absolute-max ratings. No power-line protection — this is a signal or low-power rail suppressor, not a mains-side MOV replacement. The 2.4A peak pulse current at the 10/1000µs shape fits data-line and control-loop protection where the source impedance limits fault current. ## Active production — sourcing through authorized channels Microchip lists the 1N6134AUS as Active. The base product number is 1N6134; the 'AUS' suffix signals the SQ-MELF package variant. Sourced per RFQ against BOM quantity — no stock-holding claim, but the active status means lead times are predictable through authorized distribution.","metaTitle":"1N6134AUS Zener TVS Diode – 500W, SQ-MELF","metaDescription":"1N6134AUS Zener TVS diode, 500W peak pulse power, 114V standoff, SQ-MELF B package.
