sistor output, providing less leakage compared to an
open collector Schottky clamped transistor output.
For the single channel type, an enable function on pin
7 allows the detector to be strobed. The internal shield
provides a guaranteed common mode transient
immunity of 5 kV/µs for the SFH6741 and SFH6751
and 10 kV/µs for the SFH6742 and SFH6752. The
use of a 0.1
µF
bypass capacitor connected between
pin 5 and 8 is recommended.

= 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.
