IL203 - PHOTOTRANSISTOR OPTOCOUPLER

General Description

The IL201/202/203 are optically coupled pairs employing a Gallium Arsenide infrared LED and a Silicon NPN phototransistor.

Signal information, including a DC level, can be transmitted by the device while maintaining a high degree of electrical isolation between input and output.

Key Features

  • High Current Transfer Ratio, 75% to 450%.
  • Minimum Current Transfer Ratio, 10%.
  • Guaranteed at IF=1mA.
  • High Collector-Emitter Voltage, BVCEO=70V.
  • Long Term Stability.
  • Industry Standard DIP Package.
  • Underwriters Lab File #E52744.
  • VDE 0884 Available with Option 1.
