EL3010S(TA)

Overview

The EL3010S(TA) is a random-phase Triac output optocoupler manufactured by Everlight Electronics. It integrates a Gallium Arsenide infrared emitting diode with a monolithic silicon photo Triac in a surface-mount 6-SMD (PDIP-6 Gull Wing) package. Key electrical parameters include a peak blocking voltage of 250 V, an isolation voltage of 5000 Vrms, and a maximum forward current of 60 mA. The device operates within a temperature range of -55°C to +100°C and features a power dissipation rating of 330 mW.

Feature Summary

• Integrates a GaAs infrared LED with a monolithic silicon random-phase photo Triac for robust signal isolation.
• Provides high insulation strength between input and output circuits rated at 5000 Vrms.
• Designed for direct interfacing between low-voltage electronic controls and AC power triacs.
• Available in a compact surface-mount 6-pin package suitable for automated assembly.

Applications

• Control of resistive and inductive loads in 115 to 240 VAC systems
• Solenoid and valve control circuits
• Lamp ballast driver interfaces

Procurement Notes

Verify the specific suffix TA against the manufacturer's latest datasheet to confirm pinout compatibility and packaging type. Ensure the selected component meets the required isolation voltage ratings for your specific safety certification standards. Cross-reference the part number with official Everlight documentation to confirm RoHS compliance status and lead-free characteristics before finalizing procurement specifications.

Selection Notes

Select this component when random-phase triggering is acceptable for the load application. The 250 V peak blocking voltage limits suitability to lower voltage AC applications compared to the 400 V or 600 V variants in the series. Verify that the 60 mA forward current capability aligns with the driving circuit's output capabilities. Consider the surface-mount footprint constraints during PCB layout design to ensure adequate thermal management and creepage distances.

Part Context

The EL3010S(TA) belongs to the EL301X series of Triac output optocouplers from Everlight. This series is characterized by its use of a monolithic silicon photo Triac coupled with a GaAs LED. The EL301X designation specifically indicates a 250 V peak blocking voltage rating, distinguishing it from the higher voltage EL302X (400 V) and EL305X (600 V) series members.

Replacement Considerations

Compatible substitutes within the same family include the EL3011S(TA) and EL3012S(TA), which share identical electrical characteristics and pin configurations but may differ in packaging style or specific regulatory approvals. Verify mechanical dimensions and soldering profiles when substituting surface-mount variants.
