Photo Coupler – Triac Driver 4pin SOP


Triac Driver 4pin SOP

The ELM30XX devices consist of a GaAs infrared emitting diode optically coupled to a photo triac driver. They are designed for use with a discrete power triac in the interface of logic systems to equipment powered from 110 to 240 VAC lines, such as solid-state relays, industrial controls, motors, solenoids and consumer appliances, etc.


• Peak breakdown voltage 250V~800V
• High isolation voltage between input and output (Viso=3750 Vrms)
• Pb free and RoHS compliant

Other Applications

• Light controls
• Static power switch
• AC motor drivers
• Temperature controls
• AC Motor starters
• Solid state relays
