• Material categorization:
for definitions of compliance please see
www.vishay.com/doc?99912
AGENCY APPROVALS
i179060
• UL - file no. E52744 system code H, double protection
• DIN EN 60747-5-2 (VDE 0884), IEC 60747-5-5
DESCRIPTION
• DIN EN 60747-5-5 (VDE 0884) pending
The SFH655A is 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.
• BSI IEC 60950; IEC 60065
This optocouplers can be used to replace reed and mercury
relays with advantages of long life, high speed switching and
elimination of magnetic fields.
