ELM3052(TA)

Triac, SCR Output Optoisolators Overview

The ELM3052(TA) is a single-channel triac output optocoupler manufactured by Everlight Electronics. It features an infrared emitting diode coupled to a six-layer monolithic silicon triac, providing electrical isolation with a high dielectric strength of 3750 Vrms. The device operates within a temperature range of -40°C to +110°C and supports a peak repetitive off-state voltage of 600V. Packaged in a surface-mount SOP-4 configuration with a 2.54mm lead pitch, it is designed for random-phase triggering applications requiring robust isolation between control and power circuits.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to ensure compatibility with required insulation standards and packaging formats. Confirm that the selected variant meets the necessary safety certifications for the target application environment. Cross-reference the component marking with official Everlight documentation to prevent substitution errors during production integration.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase triac triggering is required rather than zero-crossing functionality. Ensure the input forward current requirements align with the driving logic levels available in the system design. Verify that the operating temperature range covers the maximum ambient conditions expected in the final enclosure or industrial setting.

Triac, SCR Output Optoisolators Part Context

This part belongs to the EL305x series of triac output optocouplers from Everlight. It serves as a surface-mount alternative to through-hole variants like the EL3052, offering similar electrical characteristics in a smaller footprint. The series is widely used in consumer electronics and industrial controls where space constraints and isolation requirements must be balanced effectively.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes include the EL3052(SR) and EL3052(X008-TA). Verify pinout compatibility and isolation voltage ratings before swapping components in existing designs.
