3N261TX

Overview

The 3N261TX is a single-channel transistor output optocoupler manufactured by TT Electronics/Optek Technology. It provides electrical isolation with a maximum output voltage of 30V and a collector current rating of 30mA. The device features a minimum current transfer ratio of 30% at a forward current of 10mA, with a typical rise and fall time of 10µs. It operates within a temperature range of -55°C to 125°C and utilizes a TO-72-4 metal can package for through-hole mounting.

Feature Summary

Provides high-voltage isolation between input and output circuits
Utilizes a robust metal can package for environmental protection
Features fast switching characteristics suitable for digital signal transmission

Applications

Industrial control systems requiring galvanic isolation
Signal transmission in noisy electrical environments
Interface circuits for microprocessor-based systems

Procurement Notes

Verify the specific suffix 'TX' against official manufacturer documentation to confirm tape-and-reel packaging requirements. Ensure compatibility with existing TO-72 footprints and validate thermal management strategies for operation near the upper temperature limit. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement specifications.

Selection Notes

Select this component when high isolation voltage and wide operating temperature ranges are required. The TO-72 package offers superior durability compared to plastic alternatives. Verify that the 30mA collector current meets load requirements and that the 10µs switching speed aligns with system timing constraints.

Part Context

This part belongs to the standard transistor output optocoupler family from TT Electronics/Optek Technology. It shares functional similarities with other models in the series but is distinguished by its specific packaging and performance parameters designed for industrial reliability.
