Excelitas Technologies Corp. Planar Silicon Photodiode VTB4051H

The VTB4051H is a blue-enhanced silicon photodiode in a 8 mm recessed ceramic package protected with a clear epoxy layer. This photodiode provides an enhanced response in the blue spectral range, as well as exhibits a very high shunt resistance and a low dark current.

Applications:

• UV and blue light sensing
• Light meters
• Flame monitoring
• Photometry

Isolator, Analog Optical, Axial leaded, 2.0 V @ 20 mA (LED), 40 mA (Max.) (LED), -40 degC, 75 degC
This light tight package which houses a light source and one or more photoconductive cells. Through control of the input current or applied voltage, the output resistance can be varied. The output resistance can be made to switch between ""on"" and ""off"" state or made to track the input signal in an analog manner.

• High input-to-output voltage isolation.
  
• True resistance element output.
  
• SIngle or dual element outputs available.
  
• Low cost
  
• Suitable for AC or DC use
  
• Wide range of input to output characteristics
  
• Low drive current.
