Part Number: 6N139-V

Description:
The 6N138 and 6N139 devices each consists of an infrared emitting diode, optically coupled to a
high gain split Darlington photo detector. They provide extremely high current transfer ratio
between input and output, with access to a base terminal to adjust the gain bandwidth.These devices
are packaged in an 8-pin DIP package and available in wide-lead spacing and SMD options.

Features:
High current transfer ratio–2000% typical
High isolation voltage between input and output (Viso=5000 Vrms )
Guaranteed performance from 0°C to 70°C
Pb free and RoHS compliant.
