**Alpha & Omega Semicon** · MOSFETs · TSOP-6

AO6420 from Alpha & Omega Semicon, in a TSOP-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, internally connected to the other drain pins (2, 5, 6); VDS rated 60V and continuous ID 4.2A at TA=25°C. |
| 2 | D | passive | Drain, internally connected to the other drain pins (1, 5, 6); VDS rated 60V and continuous ID 4.2A at TA=25°C. |
| 3 | G | input | Gate, with maximum gate-source voltage of ±20V and threshold VGS(th) of 1V min to 3V max. |
| 4 | S | passive | Source, the only source pin; maximum body-diode continuous current is 3A. |
| 5 | D | passive | Drain, internally connected to the other drain pins (1, 2, 6); pulsed drain current up to 20A. |
| 6 | D | passive | Drain, internally connected to the other drain pins (1, 2, 5); VDS rated 60V and RDS(ON) below 60mΩ at VGS=10V. |

## CAD (KiCad official)

- Symbol: `AO6420`
- Footprint: `Package_SO:TSOP-6_1.65x3.05mm_P0.95mm`
- 3D model: TSOP-6 (KiCad packages3D, STEP)
- 3D model files: `ao6420-etched.step` / `ao6420-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ao6420.step` / `ao6420.glb` are the bare package body.
