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 dierent
potentials and impedances
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.

Solder Reow Temperature Prole
1. One-time soldering reow is recommended within
the condition of temperature and time prole 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.
Note: Non-halide ux should be used.
