Housed in the compact SMA (DO-214AC) surface-mount package, it combines the current-carrying capability of a power rectifier with the ultra-fast 25 ns reverse recovery time needed for high-frequency switching applications. The device exhibits a low forward voltage drop of 775 mV at 1 A and a typical reverse leakage current of only 2 \u00b5A. With a maximum junction temperature rating of 175\u00b0C and AEC-Q101 qualification, the MURA110T3G is well suited for demanding automotive and industrial power conversion circuits where both speed and reliability are essential.","working_principle":"The MURA110T3G utilizes a PIN (P-Intrinsic-N) rectifier structure optimized for ultra-fast reverse recovery. During forward conduction, minority carriers are injected into the intrinsic region, creating a low forward voltage drop. When the applied voltage reverses, these stored carriers must be swept out before the diode can block. The MURA110T3G employs controlled platinum doping that creates recombination centers in the silicon, dramatically accelerating carrier recombination and reducing the reverse recovery time to just 25 ns. This results in significantly lower switching losses compared to standard PN junction rectifiers, making it ideal for high-frequency switch-mode power supplies and freewheeling applications where fast turn-off minimizes power dissipation.","pin_description":"
