**Diodes Incorporated** · Voltage References · SOT-23

ZRC250F02TA from Diodes Incorporated, in a SOT-23. 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 | NC | unconnected | Pin 1 is left floating or connected to pin 2 (GND), per the pin assignment note. |
| 2 | GND | power_in | Ground/anode reference terminal; pin 1 may be tied to it, and voltages are specified relative to GND. |
| 3 | VR | passive | Reference voltage terminal providing 2.5 V nominal (2% tolerance for this -F02 variant) at a recommended operating current of 20 µA to 5 mA. |
