EL3061-V

Overview

The EL3061-V is a single-channel optoisolator featuring a triac output and integrated zero-crossing detection circuit. It provides high isolation voltage of 5000 Vrms between input and output sections. The device incorporates a GaAs infrared emitting diode optically coupled to a monolithic silicon photo-triac. Key electrical parameters include a maximum peak blocking voltage (VDRM) of 600 V, a static dV/dt rating of 1 kV/μs, and an RMS on-state current of 100 mA. The component operates within a temperature range of -55°C to 100°C.

Feature Summary

• Integrated zero-voltage crossing circuitry for reduced electromagnetic interference during switching
• High isolation voltage capability ensuring safe interface between logic systems and AC lines
• Monolithic silicon construction combining infrared LED with photo-triac for compact design

Applications

• Solid-state relays
• Industrial motor controls
• AC motor drivers
• Solenoid and valve controls

Procurement Notes

Verify the specific suffix designation when ordering, as variations may exist regarding packaging or compliance certifications. Confirm that the selected variant matches the required isolation voltage and trigger current specifications for the target application. Ensure compatibility with standard DIP-6 mounting processes and reflow soldering profiles specified in the manufacturer's technical documentation.

Selection Notes

Select this component for applications requiring reliable AC load control with minimal noise generation. The zero-crossing feature makes it suitable for sensitive electronic environments where switching transients must be minimized. Consider the 600 V blocking voltage limit when designing circuits for higher voltage AC lines. Verify that the 100 mA RMS output current meets the load requirements before integration.

Part Context

This part belongs to the EL306X series of zero-crossing triac driver photocouplers manufactured by Everlight Electronics. The series is designed for interfacing low-voltage logic systems with medium-voltage AC power lines. These devices are commonly used in consumer appliances and industrial equipment where galvanic isolation is required for safety and signal integrity.

Replacement Considerations

Compatible substitutes include other zero-crossing triac optocouplers from various manufacturers such as MOC3061 or HCPL-306J. When replacing, ensure the substitute maintains equivalent isolation voltage, trigger current characteristics, and package dimensions to fit existing PCB layouts without modification.
