SAT470

AC Input

80V

Photo-Transistor Optocoupler

Description

The SAT470 consists of a phototransistor optically coupled

to two light emitting diodes. Optical coupling between the

input IR LEDs and output phototransistor allows for high

isolation levels while maintaining low-level AC or DC signal

control capability.

The SAT470 provides an optically

isolated method of controlling many interface applications

such as telecommunications, industrial control and

instrumentation circuitry.

The SAT470 comes standard in an ultra-miniature 4 pin

SSOP package.
