LM4040DIZ-5.0 from Texas Instruments, in a TO-92-3. 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 | * | passive | This pin must be left floating or connected to the anode; TI recommends connecting it to the anode in high-EMI or high-frequency switching-noise environments. |
| 2 | Cathode | passive | Shunt current input and reverse breakdown (output) voltage pin, 5V for this LM4040DIZ-5.0 version. |
| 3 | Anode | power_in | Anode pin, normally grounded. |
