CB3401 from CBI, 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 | GATE | input | Gate terminal of the P-channel enhancement-mode MOSFET; the datasheet rates VGS at ±12 V maximum and specifies operation with gate voltages as low as 2.5 V. |
| 2 | SOURCE | passive | Source terminal of the P-channel MOSFET; the datasheet gives no separate pin limit for this terminal beyond the device ratings (VDS = -30 V, ID = -4.2 A at TA=25°C). |
| 3 | DRAIN | passive | Drain terminal of the P-channel MOSFET; rated at VDS = -30 V with continuous drain current of -4.2 A at TA=25°C (-3.5 A at TA=70°C) and pulsed drain current of -30 A. |
