EL3041

Overview

The EL3041 is a Triac and SCR output optocoupler manufactured by Everlight Electronics Co Ltd. It features a single channel with a 6-DIP package. Key electrical parameters include a maximum forward current of 60 mA, an input trigger current of 15 mA, and a peak surge current of 1 A. The device offers a minimum off-state peak voltage of 400 V and a maximum on-state voltage of 3 V. It provides high isolation with a maximum insulation voltage of 5000 V rms and a static dV/dt of 1 kV/µs. Operating temperatures range from -55 °C to +100 °C.

Feature Summary

• Integrates a GaAs infrared emitting diode optically coupled to a zero-crossing triac driver for noise-immune switching.
• Provides high isolation voltage between input and output terminals to ensure circuit safety.
• Includes built-in zero voltage crossing functionality to minimize electromagnetic interference during switching.

Applications

• Solid state relay drivers
• Motor control circuits
• Lighting dimmer applications

Procurement Notes

Verify the specific suffix (e.g., TB or TA) against the official datasheet to confirm packaging type and compliance status. Confirm component availability as some variants may be discontinued. Ensure that the selected part meets all required safety certifications such as UL and VDE for the target application environment.

Selection Notes

Select this component when zero-crossing switching is required to reduce electrical noise in AC power control systems. Consider the 400 V blocking voltage and 100 mA RMS current rating for appropriate load handling. Verify thermal requirements within the specified operating temperature range and ensure the DIP-6 package fits the design constraints.

Part Context

The EL3041 belongs to the EL304X series of Triac output optocouplers from Everlight. This series includes devices with varying peak breakdown voltages, such as 250 V, 400 V, 600 V, and 800 V options. The EL3041 specifically addresses applications requiring 400 V blocking capability with integrated zero-crossing detection.

Replacement Considerations

MOC3041M is a publicly confirmed substitute part number offering similar Triac output and zero-crossing functionality.
