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, tr, 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
• Signal transmission between circuits of dierent
potentials and impedances

1. One-time soldering reow is recommended with-
in the condition of temperature and time prole
shown at right.
2. When using another soldering method such as in-
frared 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.
Note: Non-halide ux should be used.
