4N32-X001

Overview

The Vishay Semiconductor Opto Division 4N32-X001 is a single-channel optoisolator featuring a Darlington phototransistor output with base control. It provides high isolation resistance, typically 10^11 Ω, and operates within a voltage isolation rating of 5300Vrms. The device offers a minimum current transfer ratio of 500% at an input current of 10mA. It is housed in a standard plastic DIP-6 package (7.62mm width) and supports a wide operating temperature range from -55°C to +100°C.

Feature Summary

• Darlington phototransistor output configuration with accessible base terminal for enhanced control
• High current transfer ratio ensuring significant signal amplification capabilities
• Robust electrical isolation characteristics suitable for demanding environments

Applications

• Industrial control systems requiring high gain isolation
• Power supply feedback loops
• Signal transmission across isolated ground planes

Procurement Notes

Verify the specific suffix designation when sourcing, as it determines the packaging format such as tube or tape-and-reel configurations. Confirm that the component status aligns with project requirements, noting availability constraints for obsolete parts. Ensure the selected variant matches the required lead time and manufacturing lot specifications for production integration.

Selection Notes

Select this component when high current transfer ratio is critical for driving subsequent stages without additional amplification. The accessible base pin allows for customization of switching speed and sensitivity. Consider the DIP-6 package dimensions for PCB layout compatibility and verify thermal management needs given the operational temperature range limits.

Part Context

This part belongs to the Vishay 4N3x series of transistor output optocouplers. It distinguishes itself from standard variants like the 4N37 by utilizing a Darlington pair structure, which significantly increases the current gain. This family is designed for general-purpose isolation applications where higher sensitivity is required compared to single-transistor outputs.

Replacement Considerations

Direct substitutes include other Darlington output optocouplers with similar isolation ratings and package footprints. Verify pinout compatibility and ensure the replacement maintains the 5300Vrms isolation requirement. Cross-reference current transfer ratio specifications to guarantee equivalent performance in high-gain applications.
