4N33-X001

Overview

The Vishay 4N33-X001 is a single-channel photodarlington output optocoupler featuring high gain with a base connection. It provides 5300Vrms isolation voltage and operates within a temperature range of -40°C to 100°C. The device utilizes a 6-DIP package and supports DC input signals. Key electrical characteristics include a minimum current transfer ratio of 500% and a maximum propagation delay of 9µs.

Feature Summary

• Photodarlington output configuration for high gain applications
• Integrated base connection on the phototransistor
• High isolation voltage rating of 5300Vrms

Applications

• General purpose logic interface circuits
• Solid-state relay driver circuits
• Microprocessor system isolation

Procurement Notes

Verify the specific suffix X001 against official Vishay documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with required isolation standards and operating temperature ranges before integration into final designs.

Selection Notes

Select this component when high current transfer ratio is required without external amplification. The integrated base allows for faster switching or lower sensitivity adjustments compared to standard photodarlington outputs.

Part Context

This part belongs to the legacy 4N33 series from Vishay Semiconductor Opto Division. It is distinct from the VO0601-X001T, which is a high-speed open-drain logic output isolator. The 4N33 series is characterized by its photodarlington output structure rather than logic gate outputs.
