AGM312D
AGM-Semi · MOSFETs · TO-252
AGM312D from AGM-Semi, in a TO-252. 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; controls the channel, with VGS limited to ±20 V and threshold VGS(th) of 1.2 V to 2.2 V. |
| 2 | D | passive | Drain, also connected to the exposed tab; VDS rated 30 V and continuous ID 20 A (package limited) at Tc=25℃. |
| 3 | S | passive | Source; body diode continuous current is 20 A with VSD max 1.2 V at IS=15A. |
