Vishay Semiconductors
DESCRIPTION
The SFH608 is an optocoupler designed for high current
transfer ratio at low input currents with the output transistor
saturated. This makes the device ideal for low current
switching applications. The SFH608 is packaged in a six pin
plastic DIP.

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute maximum
ratings for extended periods of the time can adversely affect reliability.
