AGM425M

AGM Semi · MOSFETs · SOP-8

AGM425M from AGM Semi, in a SOP-8. 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 is at the marked corner of the SOP8 package.
2 G1 input Gate of MOSFET 1; the datasheet rates gate-source voltage at ±20 V for both channels.
3 S2 passive Source of MOSFET 2.
4 G2 input Gate of MOSFET 2; the datasheet rates gate-source voltage at ±20 V for both channels.
5 D2 passive Drain of MOSFET 2; the datasheet gives drain-source ratings of 40 V (N-Ch) and -40 V (P-Ch).
6 D2 passive Drain of MOSFET 2, tied to pin 5 in the package; the datasheet gives drain-source ratings of 40 V (N-Ch) and -40 V (P-Ch).
7 D1 passive Drain of MOSFET 1; the datasheet gives drain-source ratings of 40 V (N-Ch) and -40 V (P-Ch).
8 D1 passive Drain of MOSFET 1, tied to pin 7 in the package; the datasheet gives drain-source ratings of 40 V (N-Ch) and -40 V (P-Ch).
