Photovoltaic Solid-State Relay Optocouplers
Features
Description
■ 4,000 VRMS Isolation
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 generator. 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.
■ Wide operating voltage range
■ 250V (HSR312, HSR312L)
■ 400V (HSR412, HSR412L)
■ Solid-State Reliability
■ Bounce-Free Operation
■ 4000V ESD Rating (HBM)
■ UL and CSA approved
Applications
■ On/Off Hook Switch
■ Replacement for Mechanical Relays
■ Dial Out Relay
■ Ring Injection Relay
■ General Switching
■ Ground Start
