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
■

Absolute Maximum Ratings
(T
A
= 25°C unless otherwise noted)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
