ZR40402F25TA from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC/VR | passive | No internal connection; may be left floating or tied to pin 2 (VR) on the SOT23-F package. |
| 2 | Gnd | passive | Ground / anode of the shunt reference. Return path for reverse current IR (60µA to 15mA recommended). |
| 3 | VR | passive | Reverse breakdown / reference output pin (cathode of shunt reference). Regulates to 2.5V nominal (±2% for the F25TA suffix) when biased with 60µA-15mA of reverse current through an external series resistor. |
