Overview
The IS4N46X is a single-channel optocoupler featuring an infrared LED coupled to a NPN silicon phototransistor Darlington output. It provides high isolation voltage of 5300Vrms and supports a collector-emitter saturation voltage suitable for digital switching. The device operates with a forward current up to 20mA and offers a minimum current transfer ratio of 200%. It is housed in a 6-pin DIP package and functions within a temperature range of 0°C to +70°C.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Darlington output configuration providing high current gain for driving loads directly
- Compact six-pin dual in-line package design for standard PCB mounting
Applications
- Industrial control systems requiring galvanic isolation
- Signal interface circuits between microprocessors and power stages
- Solid-state relay driver applications
Procurement Notes
Verify the manufacturer designation as Isocom Components 2004 LTD or ISOCOM COMPONENTS LIMITED when sourcing. Confirm the specific suffix X indicates the tube packaging variant if required by assembly processes. Ensure compatibility with 6-DIP footprints during procurement planning.
Selection Notes
Select this component where high isolation voltage and significant current gain are necessary without external amplification. The Darlington structure allows for lower input drive currents compared to standard phototransistors. Consider the operating temperature range and package constraints relative to the target application environment.
Part Context
This part belongs to the IS4N46 series of low input current Darlington output optocouplers manufactured by Isocom Components. The series is designed for general-purpose isolation tasks, offering a balance of speed and gain. The IS4N46X represents a specific packaged version of this technology within the company's optoelectronic portfolio.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with other manufacturers requires independent verification of electrical parameters and pinout compatibility.
