DMG9926UDM-7

Diodes Incorporated · MOSFETs · SOT-26

DMG9926UDM-7 from Diodes Incorporated, in a SOT-26. 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 S1 passive Source of MOSFET 1 (pin 1 at the dot, top-left in top view).
2 D1/D2 passive Common drain of MOSFET 1 and MOSFET 2, tied to pin 5; the datasheet gives VDSS of 20 V.
3 S2 passive Source of MOSFET 2.
4 G2 input Gate of MOSFET 2; the datasheet gives VGSS of ±8 V.
5 D1/D2 passive Common drain of MOSFET 1 and MOSFET 2, tied to pin 2; the datasheet gives VDSS of 20 V.
6 G1 input Gate of MOSFET 1; the datasheet gives VGSS of ±8 V.
