MOC3053 from KTP, 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 | input | Anode of the GaAs infrared emitting diode (LED input), with the LED forward current limited to 60 mA and reverse voltage to 6 V in absolute maximum ratings. |
| 2 | Cathode | input | Cathode of the GaAs infrared emitting diode (LED input), with the LED forward current limited to 60 mA and reverse voltage to 6 V in absolute maximum ratings. |
| 3 | No Connection | unconnected | Pin is not connected internally and is labeled 'No Connection' in the pin configuration. |
| 4 | Terminal | passive | Main terminal of the photo Triac output, rated for an off-state terminal voltage of 250 V (MOC301X), 400 V (MOC302X) or 600 V (MOC305X) and an on-state RMS current of 100 mA. |
| 5 | Substrate | unconnected | Substrate of the monolithic silicon die, which must not be connected (do not connect). |
| 6 | Terminal | passive | Main terminal of the photo Triac output, rated for an off-state terminal voltage of 250 V (MOC301X), 400 V (MOC302X) or 600 V (MOC305X) and an on-state RMS current of 100 mA. |
