Description
The SFH612A and SFH655A are optically coupled
isolators with a Gallium Arsenide infrared LED and a
silicon photodarlington detector. Switching can be
achieved while maintaining a high degree of isolation
between driving and load circuits. These optocou-
plers can be used to replace reed and mercury relays
with advantages of long life, high speed switching and
elimination of magnetic fields.

Absolute Maximum Ratings
T_amb = 25 °C, unless otherwise specified
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 Rating for extended periods of the time can adversely affect reliability.
