IS4N46G

Overview

The IS4N46G is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output with an accessible base terminal, housed in a 6-pin PDIP package. The device provides an isolation voltage rating of 5300Vrms. This component is designed for applications requiring high input-to-output isolation and reliable signal transmission between circuits.

Feature Summary

• Darlington output configuration with integrated base connection
• High voltage isolation capability rated at 5300Vrms
• Single channel design for DC input to DC output coupling

Applications

• General purpose digital signal isolation
• Microcontroller interface circuits
• Low voltage switching applications

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's current datasheet to confirm lead-free compliance status. Ensure the 6-pin PDIP package matches your PCB footprint requirements. Cross-reference the 5300Vrms isolation rating with your system safety standards before procurement.

Selection Notes

Select this component when a Darlington output with base access is required for higher gain or external biasing control. The 5300Vrms isolation rating suits systems demanding robust galvanic separation. Consider the PDIP package constraints for through-hole assembly processes.

Part Context

Isocom Components specializes in infrared optoelectronic devices, including optocouplers and opto-switches. The IS4N46G belongs to their family of low input current Darlington output optoisolators, designed for general-purpose isolation tasks within electronic circuits.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs using electrical parameter matching rather than direct pin-for-pin substitution without datasheet confirmation.
