BS170-D26Z from onsemi, in a TO-92-3. 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 | Drain | passive | Drain of the N-channel MOSFET; drain-source voltage is rated 60 Vdc maximum and continuous drain current 0.5 Adc. |
| 2 | Gate | input | Gate of the N-channel MOSFET; gate-source voltage is rated ±20 Vdc continuous and ±40 Vpk non-repetitive, with threshold of 0.8 to 3.0 Vdc at 1.0 mAdc. |
| 3 | Source | passive | Source of the N-channel MOSFET, normally connected to the circuit ground or low-side return. |
