Phototransistor Photocoupler EL817 10PCS


EL817 are Photo transistor based photo coupler. A photocoupler, or optical isolator or an opto - isolator is a component that transfers electrical signals between two isolated circuits by using light. Opto - isolators prevent high voltages from affecting the system receiving the signal.

An opto-isolator connects input and output sides with a beam of light modulated by input current. It transforms useful input signal into light, sends it across the dielectric channel, captures light on the output side and transforms it back into electric signal.

QUICK SPECS:

  • Current transfer ratio (CTR : 50 ~ 600% at IF = 5mA, VCE = 5V).
  • High isolation voltage between input and output (Viso = 5000 V rms ).
  • Creepage distance > 7.62 mm.
  • Operating temperature up to + 110°C.
  • Compact small outline package.
Applications
  • Programmable controllers.
  • System appliances, measuring instruments.
  • Telecommunication equipments.
  • Home appliances, such as fan heaters, etc.
  • Signal transmission between circuits of different potentials and impedances.
