OH3172 from Nanjing Ouzhuo Tech, 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 | Supply pin with a supply range of 4.5 to 24 V, and the device includes a reverse-voltage protector on this input. |
| 2 | GND | power_in | Ground pin (地) that serves as the common return for the supply and the open-collector output. |
| 3 | Vout | output | Open-collector output that requires an external pull-up resistor RL from the supply, with VOL of 400 mV max at VCC=5 V, RL=1 kΩ, B≥BOP, and output leakage IOH of 10 µA max when B≤BRP. |
