AO4435A from UMW, 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 | S | passive | Source terminal of the -30V P-channel MOSFET; the datasheet gives no pin-specific limit, so the device ratings apply (VDS = -30V, VGS = ±20V, ID = -12A at TA = 25°C). |
| 2 | S | passive | Source terminal of the -30V P-channel MOSFET; the datasheet gives no pin-specific limit, so the device ratings apply (VDS = -30V, VGS = ±20V, ID = -12A at TA = 25°C). |
| 3 | S | passive | Source terminal of the -30V P-channel MOSFET; the datasheet gives no pin-specific limit, so the device ratings apply (VDS = -30V, VGS = ±20V, ID = -12A at TA = 25°C). |
| 4 | G | input | Gate terminal of the MOSFET, rated for gate-source voltage VGS = ±20V and specified for operation with gate voltages as low as 2.5V. |
| 5 | D | passive | Drain terminal of the -30V P-channel MOSFET; the datasheet gives no pin-specific limit, so the device ratings apply (VDS = -30V, ID = -12A at TA = 25°C). |
| 6 | D | passive | Drain terminal of the -30V P-channel MOSFET; the datasheet gives no pin-specific limit, so the device ratings apply (VDS = -30V, ID = -12A at TA = 25°C). |
| 7 | D | passive | Drain terminal of the -30V P-channel MOSFET; the datasheet gives no pin-specific limit, so the device ratings apply (VDS = -30V, ID = -12A at TA = 25°C). |
| 8 | D | passive | Drain terminal of the -30V P-channel MOSFET; the datasheet gives no pin-specific limit, so the device ratings apply (VDS = -30V, ID = -12A at TA = 25°C). |
