Photodarlington "Pill Pack"

The 61056 is an N-P-N Planar Silicon Photodarlington Transistor in a package designed to be mounted in a double-clad printed circuit board and used in low light level applications. It is available in a range of sensitivities and is lensed for minimum response to stray light. High sensitivity, low dark current leakage, and low saturation voltage make this device ideal for interfacing with TTL circuits. Available custom binned to customer specifications or screened to MIL-PRF-19500.
