4N32-X000

Overview

The Vishay 4N32-X000 is a single-channel optocoupler featuring a photodarlington output configuration. It provides high current transfer ratio performance with a minimum CTR of 500% at an input current of 10mA. The device offers robust electrical isolation with a voltage rating of 5300Vrms. Key electrical specifications include a maximum collector-emitter voltage of 80V and a maximum collector current of 100mA. The component operates within a temperature range of -55°C to +100°C and utilizes a standard 6-DIP package for through-hole mounting.

Feature Summary

• Photodarlington output structure delivers high gain characteristics suitable for low-level signal detection
• Integrated base connection allows for external control of switching speed and sensitivity
• High insulation voltage capability ensures reliable isolation between input and output circuits

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal interfacing between microcontrollers and high-voltage loads

Procurement Notes

Verify the obsolete status of this specific part number before finalizing design-in decisions, as availability may be limited or restricted to distributor surplus channels. Confirm that the 6-DIP package dimensions align with existing PCB footprints. Ensure that the photodarlington output characteristics, including slower switching speeds compared to logic outputs, meet the timing requirements of the target application circuit.

Selection Notes

Select this component when high current gain is prioritized over switching speed. The integrated base pin provides flexibility for optimizing response time via external resistance. Consider the higher power dissipation inherent in darlington structures compared to simple phototransistors. Verify that the 5300Vrms isolation rating satisfies the safety standards required for the specific application environment.

Part Context

This device belongs to the 4N3x series of optocouplers from Vishay Semiconductor Opto Division. It shares the standard 6-pin DIP form factor common to this family but distinguishes itself through the use of a photodarlington emitter-coupled logic output stage rather than a standard phototransistor. This configuration provides significantly higher current transfer ratios while maintaining compact packaging.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the obsolete status of the component.
