ZRC250F03TA 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 floating or connected to pin 2 according to the datasheet, and no other function is stated for it. |
| 2 | GND | power_in | Ground reference for the device; all absolute maximum voltages are specified relative to GND. |
| 3 | VR | passive | Voltage reference terminal with reverse breakdown voltage of 2.5 V (2.475 V to 2.525 V at IR = 150 µA) and recommended operating current of 0.02 mA to 5 mA. |
