EL4503S(TA)-V

Overview

The EL4503S(TA)-V is a high-speed optocoupler manufactured by Everlight Electronics Co Ltd. It features an 8-pin DIP package with surface mount design capabilities and supports data rates up to 1 Mbit/s. The device provides electrical isolation of 5000 Vrms between input and output channels. Key electrical parameters include a typical forward voltage of 1.45 V, a maximum DC forward current of 25 mA, and an output channel current of 8 mA. It complies with RoHS3 standards.

Feature Summary

• High-speed signal transmission capability supporting 1 Mbit/s data rates
• Strong electrical isolation performance rated at 5000 Vrms
• Compact 8-pin surface mount package design for efficient PCB integration

Applications

• Industrial communication interfaces requiring galvanic isolation
• Microcontroller input/output isolation circuits
• Signal transmission in noisy electromagnetic environments

Procurement Notes

Verify the specific suffix TA against official Everlight documentation to confirm pin configuration and packaging details. Ensure compliance requirements match project specifications, particularly regarding RoHS3 status. Cross-reference the manufacturer part number C170000054 for accurate ordering and traceability during procurement processes.

Selection Notes

Select this component when high-speed digital isolation is required within a compact footprint. The 1 Mbit/s speed rating suits applications needing faster response than standard logic couplers. Verify that the 5000 Vrms isolation voltage meets system safety standards. Confirm that the 8 mA output current capability aligns with downstream load requirements.

Part Context

This device belongs to Everlight's high-speed optocoupler family, designed for robust signal transfer across isolated boundaries. It shares functional similarities with other models like ELM453 but offers specific packaging and parameter configurations tailored for space-constrained designs. The series emphasizes reliability in industrial and consumer electronics applications.
