4N33FG

Overview

The 4N33FG is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output configuration housed in a 6-pin DIP package. The device provides a minimum isolation voltage of 5300Vrms and supports a maximum input current of 60 mA. Key electrical parameters include a typical rise time of 4µs and a typical fall time of 3µs.

Feature Summary

• Darlington transistor output for high current transfer ratio
• Single channel design with 6-pin DIP packaging
• High isolation voltage rating of 5300Vrms

Applications

• General purpose signal isolation
• Microprocessor interface circuits
• Logic level shifting

Procurement Notes

Verify the specific manufacturer designation, as Isocom Components often supplies replacement equivalents to standard industry part numbers. Confirm that the 6-pin DIP package and Darlington output type match the target circuit requirements. Ensure the component meets the required isolation voltage specifications for the intended application environment before finalizing procurement.

Selection Notes

Select this component when a high current transfer ratio is required due to the Darlington output stage. The 6-pin DIP form factor is suitable for through-hole mounting applications. Consider the 5300Vrms isolation rating for safety-critical interfaces. Verify compatibility with the system's input current limits, which are specified at 60 mA maximum.

Part Context

Isocom Components 2004 LTD specializes in infrared optoelectronic devices, including optocouplers and opto-switches. The company provides replacement alternatives for common commercial optocoupler standards. This product line emphasizes high performance and flexible manufacturing capabilities to meet specific customer circuit design requirements.

Replacement Considerations

This component serves as an alternative to standard 4N33 series optocouplers. Verify pinout compatibility and electrical parameter equivalence against the original design specification.
