CPC1001N from Littelfuse IXYS, in a SOP-4-2.54mm. 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 | + Control | passive | Positive LED (input) terminal; input control current is limited to 5 mA continuous (1 A peak for 10 ms) with 5 V maximum reverse input voltage. |
| 2 | , Control | passive | Negative LED (input) terminal; input reverse voltage is limited to 5 V and input power dissipation to 150 mW at 25ºC. |
| 3 | Load | passive | Phototransistor output terminal; blocking voltage BVCEO is 30 V minimum and the load is rated for 100 mA continuous, with phototransistor dissipation of 150 mW at 25ºC. |
| 4 | Load | passive | Phototransistor output terminal, the second side of the output switch; same 30 V minimum BVCEO and 100 mA continuous load rating apply. |
