EL3061

Overview

The EL3061 is a zero-voltage crossing triac driver photocoupler from Everlight Electronics. It integrates a GaAs infrared emitting diode with a monolithic silicon photo triac featuring an internal zero-crossing detection circuit. The device provides high isolation voltage of 5000 Vrms and supports peak breakdown voltages up to 600V. Designed for through-hole mounting in a PDIP-6 package, it operates within a temperature range of -55°C to +100°C. This component interfaces logic systems with AC power lines ranging from 110 to 380 VAC, ensuring reliable switching with minimal electromagnetic interference.

Feature Summary

• Integrates a GaAs infrared LED optically coupled to a monolithic silicon photo triac
• Includes an internal zero-voltage crossing circuit for reduced noise generation
• Provides high insulation voltage between input and output terminals
• Compliant with RoHS standards and lead-free manufacturing processes

Applications

• Solid-state relays
• Industrial motor controls
• Solenoid and valve actuation
• Consumer appliance switches

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and compliance status. Confirm that the selected variant matches the required DIP-6 package configuration and thermal specifications for the intended operating environment before finalizing procurement orders.

Selection Notes

Select this component when interfacing low-voltage logic circuits with AC mains loads requiring noise reduction. The integrated zero-crossing feature minimizes electrical stress on connected equipment. Ensure the load current does not exceed the triac's rated capacity and verify that the isolation requirements are met by the 5000 Vrms specification.

Part Context

The EL3061 belongs to the EL306X series of zero-crossing triac driver optocouplers. This family includes variants with different peak blocking voltages, such as the EL303X (250V), EL304X (400V), and EL308X (800V). All members share similar architectural features, including the monolithic silicon triac output and infrared LED input, tailored for various AC line voltage applications.

Replacement Considerations

Compatible substitutes include other zero-crossing triac drivers with matching 600V blocking voltage and 5000 Vrms isolation, such as the MOC3061 or LTV-3061. Verify pinout compatibility and trigger current specifications to ensure seamless integration into existing PCB layouts without redesign.
