IS4N45XG

Overview

The IS4N45XG is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output with an accessible base terminal, housed in a 6-pin DIP package. The device provides a high isolation voltage of 5300Vrms. Key electrical parameters include a maximum forward voltage of 1.65V, a maximum input current of 60mA, and a typical rise time of 4.6µs. The current transfer ratio ranges from a minimum of 160% to a maximum of 320%, with a typical fall time of 15µs.

Feature Summary

• Integrates a Darlington compound transistor output structure for high gain amplification
• Includes an accessible base terminal on the phototransistor for external circuit control
• Provides galvanic isolation between input and output circuits

Applications

• High-gain signal isolation interfaces
• DC-AC converter circuits requiring precise switching control
• Industrial control systems needing robust noise immunity

Procurement Notes

Verify the specific suffix 'XG' against official manufacturer documentation to confirm packaging and compliance details. Ensure the component matches the required 6-pin DIP form factor and that the Darlington output characteristics align with the target application's gain requirements before finalizing procurement.

Selection Notes

Select this component when high current transfer ratios are necessary without external amplification. The accessible base pin allows for customization of switching speed or sensitivity. Confirm that the 5300Vrms isolation rating meets the safety standards of the intended system environment.
