LM4041DFTA 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 | CATHODE | passive | Shunt reference cathode that sets the fixed 1.225 V reference voltage, operating over a 60 µA to 12 mA reverse current range. |
| 2 | ANODE | power_in | Anode of the shunt reference, connected to the circuit ground/most negative node. |
| 3 | N/C | unconnected | No connection; must be left floating or connected to pin 2 (anode). |
