STS1DNC45 from STMicroelectronics, in a SO-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 (N-channel, VDSS 450 V, ID 0.4 A continuous at TC = 25°C). |
| 2 | G1 | input | Gate of MOSFET 1, with absolute maximum gate-source voltage of ±30 V. |
| 3 | S2 | passive | Source of MOSFET 2 (N-channel, VDSS 450 V, ID 0.4 A continuous at TC = 25°C). |
| 4 | G2 | input | Gate of MOSFET 2, with absolute maximum gate-source voltage of ±30 V. |
| 5 | D2 | passive | Drain of MOSFET 2, tied to pin 6, with drain-source voltage rating of 450 V. |
| 6 | D2 | passive | Drain of MOSFET 2, tied to pin 5, with drain-source voltage rating of 450 V. |
| 7 | D1 | passive | Drain of MOSFET 1, tied to pin 8, with drain-source voltage rating of 450 V. |
| 8 | D1 | passive | Drain of MOSFET 1, tied to pin 7, with drain-source voltage rating of 450 V. |
