EL3023

Overview

The EL3023 is a random-phase Triac output optocoupler manufactured by Everlight Electronics. It features a single channel with a PhotoTriac output and operates within a temperature range of -55°C to +100°C. Key electrical parameters include an isolation voltage of 5000 Vrms, a forward current (If) of 60 mA, and a forward voltage (Vf) of 1.18 V. The device supports a peak repetitive off-state voltage (VDRM) of 400 V and has a maximum trigger current of 5 mA. Power dissipation is rated at 330 mW. It is housed in a PDIP-6 package for through-hole mounting.

Feature Summary

• Random-phase Triac output configuration for AC power control applications
• High insulation voltage capability of 5000 Vrms for safety isolation
• Wide operating temperature range from -55°C to +100°C
• Integrated LED driver with low trigger current requirements

Applications

• AC motor speed control circuits
• Solid-state relay designs
• Lighting dimmer applications
• General purpose AC load switching

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging options such as tube quantities against current supply constraints. Ensure the ordering suffix matches the required package type and lead-free specifications. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when random-phase triggering is acceptable for the AC load application. Consider the 400 V blocking voltage limit relative to the line voltage. Evaluate the 60 mA forward current requirement for the driving circuit design. Compare against zero-crossing variants if noise reduction is critical. Verify thermal management needs given the 330 mW power dissipation rating in the PDIP-6 package.

Part Context

The EL3023 belongs to the EL302X series of Triac output optocouplers from Everlight. This family provides galvanic isolation between control logic and high-voltage AC loads. The EL3023 specifically offers random-phase triggering, distinguishing it from zero-crossing models like the EL3021. It serves as a standard solution for basic AC switching tasks requiring moderate isolation voltages.

Replacement Considerations

Check for pin-compatible alternatives within the EL302X series. Verify that substitute parts maintain the same 5000 Vrms isolation and 400 V VDRM ratings. Ensure the replacement device supports the required 60 mA If and 5 mA Ift specifications. Confirm package compatibility for existing PCB layouts.
