# SE7N70

**SINO-IC** · MOSFETs · TO-220F

SE7N70 from SINO-IC, in a TO-220F. 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 control input of the N-channel MOSFET, with a gate-source voltage rating of ±30 V and a gate threshold of 2.0 to 4.0 V. |
| 2 | D | passive | Drain terminal with a 700 V drain-source voltage rating and 8 A continuous drain current. |
| 3 | S | passive | Source terminal of the MOSFET, which is the return for the 8 A continuous drain current. |
