Vishay, TCMT1108 Phototransistor Output Optocoupler, Surface Mount, 4-Pin SOP

The Vishay The TCMT110 series Optocoupler 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.

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
