TO-99 Package

Optocoupler is a device that has both a light source and a light detector in the same package or IC [integrated Circuit]. An external signal causes the light source to be emitted and than coupled to the light detector. The output of the detector is than used as a control signal in another part of the circuit. Optocouplers can be used to separate circuits from noise or other sources of interference between different circuit elements [Optoisolator]. Note outputs may be transistor/analog or IC/digital outputs. Transition speed is device specific. Note optocouplers are by definition galvanic isolation optocouplers. TO-99 Mechanical Drawing
