STMICROELECTRONICS MJD31CT4 Power Transistor

The MJD31C is a low-voltage NPN power transistor designed for use in general-purpose linear and switching applications. It features a surface-mount DPAK (TO-252) package, manufactured using planar technology with a base island layout for high gain performance and very low saturation voltage. It delivers collector-emitter voltages up to 100V, collector currents of 3A, and incorporates thermal resistance of 8.3 °C/W junction-case and 50 °C/W junction-ambient. Suitable for various linear and switching circuits requiring high efficiency and reliable operation.
