VBsemi Elec · MOSFETs · SOT-23

DMG2305UX-13-VB from VBsemi Elec, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate-source voltage is rated at ±8 V (VGS), and the gate-source leakage is specified at ±100 nA maximum at VGS = ±8 V.
2 S passive Continuous source current (diode conduction) is rated at -2.5 A (IS), with a pulsed source current of -20 A (ISM).
3 D passive Drain-source voltage is rated at -20 V (VDS) with continuous drain current of -5 A at TC = 25 °C (ID), and the part is specified for operating junction and storage temperature from -55 °C to +175 °C.
