AH9246-P-B from Diodes Incorporated, in a TO-92. 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 | VDD | power_in | Power supply pin, operating range 2.5V to 5.5V (absolute maximum 7V). |
| 2 | GND | power_in | Ground pin. |
| 3 | OUTPUT | output | Digital output with built-in 100k pull-up resistor; goes low (on) when the magnetic flux exceeds BOP of either pole, with maximum output current 1.0mA. |
