3N244TX

Overview

The 3N244TX is a single-channel optoisolator manufactured by TT Electronics/Optek Technology, housed in a TO-72-4 metal can package. It features an NPN phototransistor output with a maximum collector-emitter voltage of 30V and a continuous collector current of 30mA. The device provides 1000VDC isolation voltage between input and output circuits. Key electrical parameters include a typical forward voltage of 1.3V, a maximum DC forward current of 40mA, and a saturation voltage of 300mV. The minimum current transfer ratio is 30% at 10mA input. Switching characteristics specify typical rise and fall times of 10µs. It operates within a temperature range of -55°C to 125°C.

Feature Summary

Provides galvanic isolation for signal transmission between separate electrical circuits
Utilizes a robust metal can package designed for through-hole mounting
Features high isolation voltage capability for noise immunity
Delivers fast switching performance suitable for digital signal applications

Applications

Industrial control systems requiring circuit isolation
Solid-state relay driver circuits
Logic-to-ground interfacing in microprocessor systems
Power supply feedback loops

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact switching speed or packaging variations. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Cross-reference the full part number with the latest datasheet revision to validate all electrical specifications match the design requirements.

Selection Notes

Select this component when a hermetically sealed metal package is required for harsh environments. The TO-72-4 form factor supports reliable through-hole assembly processes. Evaluate the 300mV saturation voltage for low-power dissipation needs. Consider the 10µs switching speed for timing constraints in digital communication interfaces. Verify that the 1000VDC isolation rating meets safety standards for the target application voltage levels.

Part Context

This device belongs to the standard transistor-output optocoupler family produced by TT Electronics/Optek Technology. It represents a legacy component utilizing traditional metal can construction rather than modern plastic surface-mount packages. The series is designed for general-purpose isolation tasks where long-term reliability and environmental stability are prioritized over miniaturization.
