Phototransistor Output | Vishay

The TCMT110. series consist of a phototransistor optically coupled to a gallium arsenide infrared-emitting diode in a 4 pin package. The elements are mounted on one leadframe providing a fixed distance between input and output for highest safety requirements.

Features & Benefits:

  • Low profile package (half pitch)
  • AC isolation test voltage 3750 VRMS
  • Low coupling capacitance of typical 0.3 pF
  • Current transfer ratio (CTR) selected into groups
  • Low temperature coefficient of CTR
  • Wide ambient temperature range


  • Programmable logic controllers
  • Modems
  • Answering machines
  • General applications
