Frequently Asked Questions
Can these optocouplers be used in life support systems?
No, Fairchild's products are not authorized for use as critical components in life support devices or systems without direct written approval.
What is the minimum I-O isolation voltage required for a black package?
The I-O isolation voltage must meet at least 5300 Vac(rms) when tested for one minute.
How should power dissipation be derated from ambient temperature?
The total device power dissipation (for LED plus detector) must be linearly derated from the value established at 25°C ambient operating temperature.
What does the '-M' suffix signify regarding the package type?
The '-M' suffix indicates that the unit is available in a White Package, whereas units without this suffix are in a Black Package.
