Photo Coupler – Photo Transistor 4Pin DIP-DC


Photo Transistor 4Pin DIP-DC

The EL81X series of devices each consist of an infrared emitting diodes, optically coupled to a phototransistor detector.
They are packaged in a 4-pin DIP package and available in wide-lead spacing and SMD option.


• Current transfer ratio (CTR: 50~600% at IF =5mA,VCE =5V)
• High isolation voltage between input and output (Viso=5000 Vrms )
• Pb free and RoHS and Halogen free compliant

Other Applications

• Programmable controllers
• System appliances,measuring instruments
• Home appliances such as fan heaters etc.
• Signal transmission between circuits of different potentials and impedances
