Description
The HSR312 and HSR412 devices consist of a AlGaAs
infrared emitting diode optically coupled to a power
MOSFET detector which is driven by a photovoltaic gen-
erator. The devices are housed in a 6-pin dual-in-line
package. The HSR312L and HSR412L employ an active
current limit circuitry enabling the device to withstand
current surge transients.
Applications
■
On/Off Hook Switch
■
Replacement for Mechanical Relays
■
Dial Out Relay
■
Ring Injection Relay
■
General Switching
