DESCRIPTION
The 61050 is an N-P-N Planar Silicon photodarlington in a lensed TO-46 three-lead package. Photodarlington devices are
ideal in applications requiring more current gain than is possible using a phototransistor. Available custom binned to
customer specifications or screened to MIL-PRF-19500.
