SMMBFJ177LT1G from onsemi, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Drain | passive | Drain; main current terminal with maximum drain-gate voltage rating of -25 V, zero-gate-voltage drain current (IDSS) of -1.5 to -20 mAdc, and drain-source on-resistance of 300 Ω maximum. |
| 2 | Source | passive | Source; current return terminal with zero-gate-voltage drain current (IDSS) of -1.5 to -20 mAdc at VDS = -15 V and VGS = 0. |
| 3 | Gate | input | Gate; depletion-mode control input with gate-source breakdown voltage of 30 Vdc minimum, gate-source cutoff voltage of 0.8 to 2.5 Vdc, and gate reverse current of 1.0 nAdc maximum. |
