IS4N46XG

Overview

The IS4N46XG is a high-speed optocoupler manufactured by Isocom Components. It features a single channel with a photodarlington output configuration housed in a DIP-6 package. The device provides an isolation voltage of 3750 Vrms and supports a data rate of 100 kb/s. Key electrical parameters include a forward current of 20 mA, a forward voltage of 1.4 V, and a reverse voltage rating of 5 V. The unit operates within a temperature range of 0°C to +70°C and has a power dissipation capacity of 100 mW.

Feature Summary

• High-speed signal transmission capability for digital isolation applications
• Photodarlington output structure providing high current transfer ratio
• Robust insulation barrier rated at 3750 Vrms for safety compliance

Applications

• Industrial control systems requiring galvanic isolation
• Power supply protection circuits
• Communication interface isolation

Procurement Notes

Verify the specific suffix 'XG' against official Isocom documentation to confirm tape-and-reel packaging or RoHS status, as datasheets may vary by revision. Confirm availability through authorized distributors, as this component may be subject to limited stock or end-of-life restrictions depending on the manufacturing batch date code.

Selection Notes

Select this component when a photodarlington output is required for high gain applications rather than standard transistor outputs. Ensure the 100 kb/s data rate meets system timing requirements. Verify that the DIP-6 package dimensions fit the PCB layout constraints and that the 3750 Vrms isolation level satisfies the specific safety standards of the target equipment design.

Part Context

This part belongs to the 4N series of optocouplers produced by Isocom Components. The manufacturer specializes in infrared optoelectronic devices and often provides alternatives to discontinued industry-standard components. The IS4N46XG variant maintains the functional characteristics of the base 4N46 model while adhering to Isocom's specific manufacturing and parameter selection standards.

Replacement Considerations

Direct substitutes include the Broadcom/Avago 4N46#060 (through-hole) and 4N46-500E (surface mount). Verify pinout compatibility and ensure the replacement device meets the same 3750 Vrms isolation and 100 kb/s speed requirements.
