IS5G

Overview

The IS5G is a high-density phototransistor optically coupled isolator manufactured by Isocom Components 2004 LTD. It features a single channel with transistor output and an integrated base for enhanced performance. The device provides 5300Vrms isolation voltage and operates within a 6-DIP package. Key electrical characteristics include a collector-emitter breakdown voltage of 80V, a collector current of 50mA, and a propagation delay of 2.6µs rise and 2.2µs fall times. The current transfer ratio ranges from 50% to 400%, ensuring reliable signal transmission across the isolation barrier.

Feature Summary

• Integrated base terminal on the phototransistor output for improved switching speed and sensitivity control
• High isolation voltage capability of 5300Vrms for robust noise immunity in industrial environments
• Fast response times with specified rise and fall delays suitable for digital signal isolation
• Wide current transfer ratio range allowing flexibility in drive circuit design

Applications

• Industrial automation systems requiring galvanic isolation between control logic and power stages
• Solid-state relays where fast switching and high isolation are critical
• Microprocessor interface circuits for protecting sensitive inputs from high-voltage transients
• Power supply feedback loops for maintaining safety separation between primary and secondary sides

Procurement Notes

Verify the specific suffix designation against official Isocom Components 2004 LTD documentation to confirm pinout compatibility and packaging type. Ensure that the required isolation voltage and current transfer ratio meet your system's safety standards. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing specifications before finalizing procurement orders.

Selection Notes

Select the IS5G when a single-channel optocoupler with an integrated base is required for faster switching applications compared to standard phototransistor outputs. Consider the 5300Vrms isolation rating for applications demanding high dielectric strength. Evaluate the 50-400% CTR range to ensure adequate margin for your specific LED drive current and load requirements while maintaining signal integrity.
