CTR vs. IF Characteristics
As shown in Figure 8, the CTR of a single-transistor output optocoupler (such as the PS2501 and PS2505 optocouplers) is at
most 20% in a low-current area (e.g. I
F
= 0.1 mA). However, the CTR of a Darlington-transistor output optocoupler (such as the
PS2502 and PS2506 optocouplers) can be greater than 200% in a low-current area (e.g. I
F
= 0.1 mA).

CONCLUSION
Demand for optocouplers featuring higher insulation and noise elimination is steadily increasing. At the same time, various
problems (change of characteristics by ambient temperature and time elapse) will occur in their circuit design. We hope this
manual will be helpful in solving such problems.
