Overview
The EL3021 is a random-phase Triac driver photocoupler manufactured by Everlight Electronics. It integrates an AlGaAs infrared LED with a light-sensitive Triac output in a PDIP-6 package. The device provides electrical isolation of 5000Vrms and supports an operating temperature range from -55°C to +100°C. Key electrical parameters include a peak off-state voltage (400PBV) and a forward voltage of 1.18V for the input LED.
Feature Summary
- Random-phase Triac output design suitable for AC power control applications
- High-voltage isolation capability up to 5000Vrms between input and output circuits
- Wide operating temperature range extending from -55°C to +100°C
Applications
- AC motor speed control systems
- Solid-state relay modules
- Lighting dimmer circuits
Procurement Notes
Verify component authenticity through authorized channels, as supply availability may be restricted. Confirm package integrity and pin alignment against the official datasheet specifications. Ensure compliance with RoHS requirements and check for specific ordering suffixes that may indicate variations in packaging or lead-free status before finalizing procurement orders.
Selection Notes
Select this component when high-voltage isolation and random-phase triggering are required for AC loads. The 400V peak off-state voltage rating determines suitability for specific line voltages. Consider the 5000Vrms isolation barrier for safety-critical designs. Evaluate thermal performance within the specified -55°C to +100°C range for environmental compatibility.
Part Context
This optocoupler belongs to the family of Triac and SCR output isolators designed for industrial and consumer AC switching. It serves as a bridge between low-voltage control logic and high-voltage AC power stages. The random-phase characteristic allows triggering at any point in the AC cycle, distinguishing it from zero-crossing variants.
Replacement Considerations
Cross-reference with other random-phase Triac driver optocouplers offering similar 5000Vrms isolation and 400V+ blocking voltage. Verify pinout compatibility for direct replacement in existing PCB layouts. Ensure equivalent forward voltage and trigger current characteristics to maintain circuit performance.
