Description
The 4N25 is an optocoupler for general purpose applica-
tions. It contains a light emitting diode optically coupled
to a photo-transistor. It is packaged in a 6-pin DIP pack-
age and available in wide-lead spacing option and lead
bend SMD option. Response time, t
r
, is typically 3 µs and
minimum CTR is 20% at input current of 10 mA.
Applications
•
I/O interfaces for computers
•
System appliances, measuring instruments

1. One-time soldering reflow is recommended within
the condition of temperature and time profile shown
at right.
2. When using another soldering method such as infrared
ray lamp, the temperature may rise partially in the mold
of the device. Keep the temperature on the package
of the device within the condition of (1) above.
