# IRF8313TR

**UMW** · MOSFETs · SOP-8

IRF8313TR from UMW, 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 terminal of MOSFET 1 (S1); the datasheet gives no separate electrical limit for this pin beyond the absolute maximum ratings for the device. |
| 2 | G1 | input | Gate terminal of MOSFET 1 (G1); the datasheet gives VGS(th) of 1 V to 2.5 V for the device and ±20 V maximum gate-source voltage in the absolute maximum ratings. |
| 3 | S2 | passive | Source terminal of MOSFET 2 (S2); the datasheet gives no separate electrical limit for this pin beyond the absolute maximum ratings for the device. |
| 4 | G2 | input | Gate terminal of MOSFET 2 (G2); the datasheet gives VGS(th) of 1 V to 2.5 V for the device and ±20 V maximum gate-source voltage in the absolute maximum ratings. |
| 5 | D1,D2 | passive | Drain terminal shared by the two MOSFET drains (D1/D2); the datasheet gives VDS maximum of 30 V for the device. |
| 6 | D1,D2 | passive | Drain terminal shared by the two MOSFET drains (D1/D2); the datasheet gives VDS maximum of 30 V for the device. |
| 7 | D1,D2 | passive | Drain terminal shared by the two MOSFET drains (D1/D2); the datasheet gives VDS maximum of 30 V for the device. |
| 8 | D1,D2 | passive | Drain terminal shared by the two MOSFET drains (D1/D2); the datasheet gives VDS maximum of 30 V for the device. |
