Description
The HCPL-181 contains a light emitting diode optically
coupled to a phototransistor. It is packaged in a 4-pin mini-
flat SMD package with a 2.0 mm profile. The small dimension
of this product allows significant space saving. The package
volume is 30% smaller than that of conventional DIP type.
Input-output isolation voltage is 3750 Vrms. Response
time, t
r
, is typically 4 μs and minimum CTR is 50% at input
current of 5 mA.

Solder Reflow Temperature Profile
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.
