**ALLPOWER ShenZhen Quan Li Semiconductor** · MOSFETs · SOP-8

AP4606B from ALLPOWER ShenZhen Quan Li Semiconductor, in a SOP-8. 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 | S2 | passive | Source of the N-channel MOSFET (VDS 30V, ID 7A continuous at 25°C). |
| 2 | G2 | input | Gate of the N-channel MOSFET, with a maximum gate-source voltage of ±20V. |
| 3 | S1 | passive | Source of the P-channel MOSFET (VDS -30V, ID -5.1A continuous at 25°C). |
| 4 | G1 | input | Gate of the P-channel MOSFET, with a maximum gate-source voltage of ±20V. |
| 5 | D1 | passive | Drain of the P-channel MOSFET, tied internally to pins 5 and 6 (VDS -30V, pulsed drain current -20.4A). |
| 6 | D1 | passive | Drain of the P-channel MOSFET, tied internally to pins 5 and 6 (VDS -30V, pulsed drain current -20.4A). |
| 7 | D2 | passive | Drain of the N-channel MOSFET, tied internally to pins 7 and 8 (VDS 30V, pulsed drain current 28A). |
| 8 | D2 | passive | Drain of the N-channel MOSFET, tied internally to pins 7 and 8 (VDS 30V, pulsed drain current 28A). |
