CYMOC3051 from OCIC, in a DIP-6. 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 | passive | Anode of the GaAs infrared LED input, with forward current rated at 60 mA max and VF 1.18 V typ and 1.5 V max at IF=20 mA. |
| 2 | CATHODE | passive | Cathode of the GaAs infrared LED input, with reverse voltage rated at 6 V max. |
| 3 | NC | unconnected | No internal connection shown in the circuit diagram, and the pin is shorted with pins 1 and 2 for the isolation test. |
| 4 | MT1 | passive | Main terminal of the photo-TRIAC output, with an off-state voltage rating of 600 V for the CYMOC305X series and an RMS on-state current of 100 mA. The datasheet does not print a terminal name for this pin. |
| 5 | NC | unconnected | No internal connection shown in the circuit diagram, and the pin is shorted with pins 4 and 6 for the isolation test. |
| 6 | MT2 | passive | Main terminal of the photo-TRIAC output, with an off-state voltage rating of 600 V for the CYMOC305X series and an RMS on-state current of 100 mA. The datasheet does not print a terminal name for this pin. |
