AH49HZ3-G1

Diodes Incorporated · Linear Hall Sensors · TO-92S

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.
