EL3053S1(TA)-V

Overview

The EL3053S1(TA)-V is a Triac and SCR output optocoupler manufactured by Everlight Electronics Co Ltd. It features a single channel with SMD/SMT installation style in a 6-SMD package. The device provides an isolation voltage of 5000 Vrms and supports an operating temperature range from -55°C to +100°C. Key electrical parameters include a forward current of 60 mA, an off-state voltage of 600 V, and a static dv/dt of 1000 V/µs.

Feature Summary

• Random-phase triac driver for AC power control applications
• High isolation voltage capability between input and output circuits
• Surface mount packaging for automated assembly processes

Applications

• AC motor speed control systems
• Solid state relay designs
• Lighting dimmer circuits

Procurement Notes

Verify the specific suffix TA against the manufacturer's latest datasheet to confirm pinout and compliance status. Ensure the selected package variant matches the PCB footprint requirements. Confirm RoHS compliance documentation is available for the specific batch before integration into regulated products.

Selection Notes

Select this component when random-phase triggering is required rather than zero-crossing detection. The 600 V off-state voltage rating suits standard AC line applications. Verify that the 1000 V/µs static dv/dt specification meets the noise immunity requirements of the target circuit environment.

Part Context

This part belongs to the EL3053 series of Triac output optocouplers. It shares the family characteristic of providing optical isolation for controlling high-voltage AC loads. The SMD variant offers space-saving advantages over through-hole DIP versions while maintaining similar electrical performance metrics.

Replacement Considerations

Check for direct substitutes within the EL3053 series or compatible random-phase triac drivers from other manufacturers. Ensure replacement parts match the 6-SMD package outline and 5000 Vrms isolation rating.
