EL3063S1(TA)-V

Overview

The EL3063S1(TA)-V is a single-channel Triac output optoisolator manufactured by Everlight Electronics Co Ltd. It features a 5000Vrms isolation voltage and integrates a zero-crossing detection circuit for precise AC load control. The device utilizes a GaAs infrared emitting diode coupled to a Triac output, housed in a 6-SMD (gull-wing) surface-mount package. Key electrical parameters include a maximum RMS on-state current of 100 mA, a peak off-state voltage of 600 V, and a minimum static dV/dt rating of 1 kV/µs. The input forward current is rated at a maximum of 60 mA with a typical forward voltage of 1.5 V. It operates within a temperature range of -55°C to 100°C.

Feature Summary

• Integrates zero-voltage crossing circuitry for reduced electromagnetic interference during switching
• Provides high isolation capability with 5000Vrms input-to-output insulation
• Features robust noise immunity with a minimum static dV/dt rating of 1 kV/µs
• Designed for surface-mount assembly in compact 6-SMD gull-wing packages

Applications

• Solid-state relay (SSR) modules
• AC motor speed control circuits
• Lighting dimmer applications
• Industrial process control systems

Procurement Notes

Verify the specific suffix TA against the manufacturer's datasheet to confirm pinout and packaging configuration. Ensure that the required isolation voltage ratings align with safety standards applicable to your target market, such as UL, VDE, or CSA certifications listed for this component series. Cross-reference the zero-crossing functionality requirements with system timing constraints before finalizing procurement.

Selection Notes

Select this component when zero-crossing switching is required to minimize inrush currents and EMI in AC loads. Compare the 600 V peak off-state voltage against the maximum line voltage plus transients in the application. Consider the 100 mA RMS current limit for load sizing. Evaluate the 6-SMD footprint compatibility with existing PCB layouts versus through-hole alternatives if space is constrained.

Part Context

This part belongs to the EL306X series of Triac output optocouplers from Everlight. The series differentiates models primarily by their peak off-state voltage ratings, with the EL306X series specifically designed for 600 V applications. It shares the same basic architecture and zero-crossing feature set as other members like the EL304X and EL308X, differing mainly in voltage blocking capabilities and specific package variants.

Replacement Considerations

Direct substitutes may include other EL306X series variants with identical zero-crossing and voltage ratings but different package suffixes. Verify pinout compatibility when replacing with generic Triac optocouplers, as lead configurations can vary between manufacturers.
