ELR3223

Triac, SCR Output Optoisolators Overview

The ELR3223 is a seven-pin DIP photo power triac photocoppler manufactured by Everlight Electronics. It features a single channel with a triac output type and lacks a zero-crossing circuit. The device provides an isolation voltage of 5000Vrms between the input LED and the output triac. It is designed for applications requiring robust electrical isolation in solid-state switching circuits.

Triac, SCR Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation via optical coupling
• Features a single-channel triac output structure
• Utilizes a standard 7-pin dual in-line package format

Triac, SCR Output Optoisolators Applications

• Three-phase solid-state contactors
• Industrial motor control systems
• AC power switching modules

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific datasheet revision to confirm pinout compatibility and thermal characteristics. Ensure that the absence of a zero-crossing feature aligns with the target application's noise requirements. Confirm the 7-DIP package dimensions match the PCB footprint constraints before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when phase-angle control or random turn-on switching is required rather than zero-voltage switching. The lack of internal zero-crossing detection makes it suitable for dimming or speed control applications where precise timing relative to the AC waveform is necessary. Consider thermal management due to the power triac output nature.

Triac, SCR Output Optoisolators Part Context

This optocoupler belongs to the family of photo power triac devices from Everlight. It serves as an interface between low-voltage control logic and high-power AC loads. The design emphasizes durability and isolation strength for industrial environments, distinguishing it from logic-level triac outputs found in consumer electronics.

Triac, SCR Output Optoisolators Replacement Considerations

Cross-reference with other Everlight triac output optocouplers lacking zero-crossing features. Verify equivalent isolation voltage ratings and peak current capabilities. Ensure mechanical footprint compatibility with existing 7-DIP layouts if substituting with similar components from other manufacturers.
