DESCRIPTION

The SFH 640 is an optocoupler with very high

BVCER, a minimum of 300 volts. It is intended for

telecommunications applications or any DC appli-

cation requiring a high blocking voltage. The

SFH640 is a “better than” replacement for H11D1.

*Supplies from this group can't always be guranteed due

to unforseeable yield spread.
