Housed in a surface-mount SQ-MELF B package, this part is suited for general-purpose circuit protection where board space is constrained but a hermetic glass-passivated die is preferred for reliability. The 22.3 V maximum clamping voltage at 22.4 A defines the upper voltage the protected circuitry sees during a surge. For a 12 V nominal rail, the 12.2 V standoff leaves margin below the clamp threshold; the 500 W peak pulse rating handles typical industrial transient events per IEC 61000-4-5 if the source impedance is high enough. Because power line protection is not specified, this device is intended for signal or low-power secondary-side rails rather than mains input stages. The bidirectional nature eliminates orientation concerns during assembly — a practical advantage for high-mix production.","metaTitle":"1N6111AUS/TR Zener TVS Diode – 500W, SQ-MELF, Active","metaDescription":"Microchip 1N6111AUS/TR Zener TVS: 500W peak pulse, 12.2V standoff, 22.3V clamp, SQ-MELF B package, -55°C to 175°C.
