ZXRE125DFTA 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 datasheet pin assignment note. |
| 2 | Gnd | power_in | Ground (anode) of the reference; pin 1 may be connected to this pin. |
| 3 | VR | passive | Reference voltage (cathode) terminal providing 1.22V nominal, with recommended operating current of 8µA to 20mA. |
