EL3041M

Overview

The EL3041M is a single-channel Triac output optocoupler manufactured by Everlight Electronics. It integrates a Gallium Arsenide infrared emitting diode with a zero-crossing Triac detector. Key electrical parameters include a maximum RMS on-state current of 100 mA, a peak off-state voltage of 400 V, and an isolation voltage of 5000 Vrms. The device operates within a temperature range of -55°C to +100°C and features a minimum static dV/dt rating of 1 kV/µs.

Feature Summary

• Integrated zero-voltage crossing circuitry for noise-immune switching
• High isolation voltage capability between input and output circuits
• Robust static dV/dt performance for reliable operation in high-noise environments

Applications

• Solid-state relay driver circuits
• AC motor control systems
• Industrial process control isolation interfaces

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package variant matches design requirements as suffixes may indicate different packaging formats without altering internal function. Review manufacturer notices for any specific handling or storage constraints associated with discontinued inventory sources.

Selection Notes

Select this component when zero-crossing detection is required for AC load control to minimize electromagnetic interference. Ensure the 400 V blocking voltage meets the application's peak line voltage requirements. Verify that the 6-DIP through-hole package fits the target PCB layout and thermal management strategy.
