Overview
The EL3051 is a random-phase triac driver optocoupler manufactured by Everlight Electronics Co Ltd. It features a single channel configuration housed in a 6-DIP package with a pin pitch of 7.62 mm. The device provides an isolation voltage of 5000 Vrms and supports a minimum off-state peak voltage of 600 V. It operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum forward current of 60 mA, a typical input trigger current of 15 mA, and a peak surge current capability of 1 A.
Feature Summary
- Random-phase triac output suitable for AC power control applications
- High isolation voltage rating of 5000 Vrms for safety compliance
- Integrated gate drive circuitry for direct triac triggering
Applications
- Solid state relays
- AC motor speed controllers
- Lighting dimmer circuits
Procurement Notes
Verify the specific suffix (e.g., -V, TA) against the manufacturer's official datasheet to ensure correct packaging and lead-free status. Confirm that the component meets UL and VDE recognition requirements if used in certified equipment. Cross-reference the part number with Everlight's current product list to confirm active status and availability of updated documentation.
Selection Notes
Select this component for applications requiring galvanic isolation between low-voltage control logic and high-voltage AC loads. Ensure the load current does not exceed the 1 A peak surge rating. Verify that the input trigger current requirements of the connected microcontroller or driver are compatible with the 15 mA typical value. Consider thermal management for operation near the upper temperature limit.
Part Context
The EL3051 belongs to the EL305X series of triac output optocouplers from Everlight. This series is designed for general-purpose AC switching applications. The device integrates an AlGaAs LED with a silicon triac detector. It is commonly used in industrial controls and consumer electronics where reliable isolation and noise immunity are required.
Replacement Considerations
Check Everlight's official substitution guide for equivalent parts within the EL305X family. Verify pin compatibility and electrical ratings before replacing with other manufacturers' triac driver optocouplers.
