Overview
The EL3042 is a single-channel Triac and SCR output optocoupler manufactured by Everlight Electronics. It features a PhotoTriac output with an integrated zero-crossing detection circuit, designed for precise AC power switching applications. The device provides high isolation capability with an insulation voltage of 5000 Vrms and supports a peak repetitive off-state voltage (VDRM) of 400 V. It operates within a temperature range of -55°C to +100°C and is housed in a PDIP-6 package.
Feature Summary
- Integrated zero-crossing detection circuit for low electromagnetic interference switching
- High isolation voltage rating of 5000 Vrms for safety compliance
- PhotoTriac output configuration suitable for AC load control
- Wide operating temperature range from -55°C to +100°C
Applications
- Solid state relays for AC load switching
- Motor speed control circuits
- Lighting dimmer applications
- Heater control systems
Procurement Notes
Verify the specific suffix variant (e.g., standard vs. -V) against the manufacturer datasheet to ensure correct packaging and electrical tolerances. Confirm RoHS compliance status through official documentation before procurement. Check current supply availability as distribution channels may vary. Ensure the PDIP-6 package matches the target PCB footprint requirements.
Selection Notes
Select this component when zero-crossing switching is required to minimize electrical noise and inrush currents in AC circuits. The 400 V VDRM rating limits suitability for higher voltage mains applications; verify load voltage requirements. Consider the 60 mA forward current limit for LED drive circuit design. Compare with similar models like EL3041 or EL3043 if different voltage ratings or pin configurations are needed.
Part Context
The EL3042 belongs to Everlight's family of Triac output optocouplers, which are engineered for industrial and consumer AC power control. These devices utilize infrared transmission between the input LED and output phototriac. The integration of zero-crossing logic distinguishes them from random-phase counterparts, offering improved performance in sensitive electronic environments.
Replacement Considerations
Direct substitutes include EL3041 and EL3043, though these lack the zero-crossing feature. Verify pin compatibility and electrical parameters such as VDRM and isolation voltage when cross-referencing with other manufacturers' equivalents.
