AGM314MD from AGM Semi, in a TO-252-4. 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 the N-channel MOSFET (Q1, 30V, 30A max continuous, 10mΩ typ RDS(on) at VGS=10V). |
| 2 | G1 | input | Gate of the N-channel MOSFET (Q1), with VGS rated ±20V and threshold of 1.2V min to 2.2V max. |
| 3 | S2 | passive | Source of the P-channel MOSFET (Q2, -30V, -20A max continuous, 21mΩ typ RDS(on) at VGS=-10V). |
| 4 | G2 | input | Gate of the P-channel MOSFET (Q2), with VGS rated ±20V and threshold of -1.2V min to -2.2V max. |
| 5 | D1/D2 | passive | Exposed tab, labelled D1/D2 in the pin-configuration drawing: drain connection for the N-channel (D1) and P-channel (D2) MOSFETs. |
