FH4606B from XIN FEI HONG, in a SO-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 | S1 | passive | Source of the N-channel MOSFET (30V, 7A continuous). |
| 2 | G1 | input | Gate of the N-channel MOSFET; VGS up to ±20V (IGSS tested at ±20V), threshold 1.0 to 2.5V. |
| 3 | S2 | passive | Source of the P-channel MOSFET (-30V, -5.5A continuous). |
| 4 | G2 | input | Gate of the P-channel MOSFET; VGS up to ±20V (IGSS tested at ±20V), threshold -1.0 to -2.5V. |
| 5 | D2 | passive | Drain of the P-channel MOSFET, connected internally to pins 5 to 8 pair D2 (VDSS -30V, pulsed IDM -22A). |
| 6 | D2 | passive | Drain of the P-channel MOSFET (VDSS -30V, pulsed IDM -22A); tie to pin 5. |
| 7 | D1 | passive | Drain of the N-channel MOSFET (VDSS 30V, pulsed IDM 28A); tie to pin 8. |
| 8 | D1 | passive | Drain of the N-channel MOSFET (VDSS 30V, pulsed IDM 28A). |
