BSS138W-7-F from Diodes Incorporated, in a SOT-323. 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 | Gate | input | Control terminal with 0-20V continuous gate-source voltage rating and gate threshold voltage of 0.5-1.5V at VDS=VGS and ID=250µA. |
| 2 | Source | power_in | Reference terminal for gate-source voltage control, typically grounded in load switch and power management applications. |
| 3 | Drain | tri_state | Drain terminal rated for 200mA maximum continuous current at 50V maximum drain-source voltage with on-resistance of 3.5Ω maximum at VGS=10V. |
