# AO6401A

**UMW** · MOSFETs · SOT-23-6

AO6401A from UMW, in a SOT-23-6. 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 | D | passive | Drain terminal of the -30 V P-channel MOSFET, rated for continuous drain current ID = -5 A at TA = 25°C per the absolute maximum table. |
| 2 | D | passive | Drain terminal of the -30 V P-channel MOSFET, rated for continuous drain current ID = -5 A at TA = 25°C per the absolute maximum table. |
| 3 | G | input | Gate terminal with a rated gate-source voltage of ±12 V, and the datasheet states the device operates with gate voltages as low as 1.8 V. |
| 4 | S | passive | Source terminal of the P-channel MOSFET, the reference for the gate-source voltage rated at ±12 V. |
| 5 | D | passive | Drain terminal of the -30 V P-channel MOSFET, rated for continuous drain current ID = -5 A at TA = 25°C per the absolute maximum table. |
| 6 | D | passive | Drain terminal of the -30 V P-channel MOSFET, rated for continuous drain current ID = -5 A at TA = 25°C per the absolute maximum table. |
