AH49HZ3-G1 from Diodes Incorporated, in a TO-92S. 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 | VCC | power_in | Power supply pin; the recommended supply range is 3 V to 8 V, with an absolute maximum supply of 10 V and an instantaneous supply of 50 V. |
| 2 | GND | power_in | Ground pin. |
| 3 | OUT | output | Linear output pin whose voltage follows the magnetic field, with quiescent output about one-half VCC at B=0 Gauss and an output resistor of 30 to 70 Ω. |
