6N138, 6N139
HIGH SPEED OPTICALLY
COUPLED ISOLATOR
PHOTODARLINGTON OUTPUT
APPROVALS
l
UL recognised, File No. E91231
DESCRIPTION
These diode-darlington optocouplers use a light
emitting diode and an integrated high gain photon
detector to provide 2500Volts
RMS
electrical isolation
between input and output. Seperate connection for
the photodiode bias and output darlington collector
improve the speed up to a hundred times that of a
conventional photo-darlington coupler by reducing
the base-collector capacitance.
