LM4040A20IDCKR from Texas Instruments, in a SC-70-5. 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 | ANODE | output | General-purpose pin, normally connected to ground; the datasheet gives no further electrical limit for this pin. |
| 2 | * | input | Must be left floating or connected to the ANODE pin; TI recommends connecting it to the anode in applications with high EMI or significant high-frequency switching noise. |
| 3 | CATHODE | bidirectional | Parallel current/voltage input; the cathode current must stay between IZ,min and 15 mA (recommended), with absolute maximum continuous cathode current of -10 mA to 25 mA. |
| 4 | NC | unconnected | No internal connection. |
| 5 | NC | unconnected | No internal connection. |
