JSMSEMI · MOSFETs · SOT-23
BSS123-JSM from JSMSEMI, in a SOT-23. 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; gate-to-source voltage is rated at ±20 V (VGSS) with a typical threshold of 1.9 V (1 V min, 2.8 V max at ID = 250 µA). |
| 2 | S | passive | Source; the MOSFET source terminal, with the body diode running from source to drain (VSD typ 0.85 V, max 1.3 V at IS = 0.3 A). |
| 3 | D | passive | Drain; drain-to-source voltage is rated at 100 V (VDSS) with continuous drain current of 170 mA and pulsed drain current of 680 mA. |
