6N138,6N139 Series
Darlington High Speed Transistor Photo Coupler
SCHEMATIC
Description
The 6N138 and 6N139 series combine an
AlGaAs infrared emitting diode as the emitter
which is optically coupled to a silicon high speed
photo darlington transistor in a plastic DIP8
package with different lead forming options.

A separate design between photodiode and
darlington transistor reduces the base-collector
capacitance of the input transistor which
PIN DEFINITION
improves the speed by several orders of
magnitude over conventional phototransistor
optocouplers.
