EL1018

Everlight Elec · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm

EL1018 from Everlight Elec, 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 Anode passive Anode of the input infrared emitting diode; the input forward current is rated at 60 mA (IF) and the reverse voltage at 6 V (VR) in the absolute maximum ratings.
2 Cathode passive Cathode of the input infrared emitting diode; the input forward current is rated at 60 mA (IF) and the reverse voltage at 6 V (VR) in the absolute maximum ratings.
3 Emitter passive Emitter of the output phototransistor; the emitter-collector voltage is rated at 7 V (VECO) in the absolute maximum ratings.
4 Collector passive Collector of the output phototransistor; the collector current is rated at 50 mA (IC) and the collector-emitter voltage at 80 V (VCEO) in the absolute maximum ratings.
