EL4503S1(TA)-V

Overview

The EL4503S1(TA)-V is a high-speed optocoupler manufactured by Everlight Electronics Co Ltd. It features an 8-pin DIP package with surface mount installation style. The device provides a data rate of 1Mbit/s and offers an isolation voltage of 5000Vrms. It contains a single channel with a transistor output configuration. The component operates within a temperature range of -55 to +100 °C and complies with RoHS standards.

Feature Summary

• High-speed signal transmission capability at 1Mbit/s
• Strong electrical isolation between input and output circuits
• Compact surface mount packaging for automated assembly

Applications

• Digital communication interfaces requiring galvanic isolation
• Microcontroller input/output isolation
• Industrial control system signal conditioning

Procurement Notes

Verify the specific suffix TA-V against the manufacturer's current datasheet to confirm pinout and compliance status. Check for recent product change notifications regarding package or material updates. Ensure the supplier provides valid traceability documentation for the 8-pin DIP format. Confirm availability through authorized channels as distribution may be restricted in certain regions.

Selection Notes

Select this component when high-speed digital isolation is required in a compact form factor. The 1Mbit/s speed suits most standard serial communication protocols. The 5000Vrms isolation rating supports applications with significant potential differences between ground domains. Verify that the transistor output interface matches the receiving circuit requirements.
