EL4502S1(TA)-V

Overview

The EL4502S1(TA)-V is a high-speed optocoupler manufactured by Everlight Electronics. It features an 8-pin DIP package with SMD mounting style and contains one channel. The device utilizes a phototransistor output type and supports a data rate of 1 Mb/s. Key electrical parameters include an insulation voltage of 5000 Vrms, a forward current of 16 mA, and a forward voltage of 1.45 V. The reverse voltage rating is 5 V, with power dissipation at 100 mW. The current transfer ratio ranges from 19% to 50%. Operating temperatures span from -55°C to +100°C.

Feature Summary

• High-speed signal transmission capability for digital isolation applications
• Phototransistor output configuration for reliable switching performance
• Robust electrical isolation suitable for noise-sensitive environments

Applications

• Digital communication interface isolation
• Microcontroller input/output isolation
• Signal transmission in industrial control systems

Procurement Notes

Verify the specific suffix TA-V against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with existing PCB footprints designed for 8-pin DIP configurations. Cross-reference the component code C170000076 or C170000071 if sourcing from distributors listing alternative identifiers. Confirm RoHS compliance status through official documentation before integration into regulated assemblies.

Selection Notes

Select this component when high-speed digital isolation is required within a standard DIP footprint. The 1 Mb/s data rate distinguishes it from slower general-purpose optocouplers. Consider the 5000 Vrms insulation rating for safety-critical circuits. Verify that the phototransistor output aligns with the downstream circuit's input requirements compared to open-collector or logic-output alternatives.

Part Context

This part belongs to Everlight's high-speed optocoupler family, designed for applications requiring fast signal transfer between isolated circuits. It serves as a surface-mount variant of the traditional DIP-8 high-speed isolators, offering similar electrical characteristics in a compact form factor suitable for automated assembly processes.
