EL3081 from Everlight Elec, 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 emitting diode (input side); the input forward current is absolutely limited to 60 mA, with a 6 V reverse voltage rating. |
| 2 | Cathode | passive | Cathode of the GaAs infrared emitting diode (input side); the LED is driven to trigger the photo triac at IF of at least IFT max 15 mA for EL3081, with absolute maximum IF of 60 mA. |
| 3 | NC | unconnected | No connection; the datasheet marks this pin as not connected. |
| 4 | Terminal | passive | Main terminal of the monolithic zero-voltage-crossing photo triac output; the EL308X series (including EL3081) is rated for an off-state terminal voltage VDRM of 800 V and an on-state RMS current of 100 mA. |
| 5 | Substrate | unconnected | Substrate pin that must not be connected (do not connect). |
| 6 | Terminal | passive | Main terminal of the monolithic zero-voltage-crossing photo triac output; the EL308X series (including EL3081) is rated for an off-state terminal voltage VDRM of 800 V and an on-state RMS current of 100 mA. |
