4N24AU

Overview

The 4N24AU is a high-reliability optically coupled isolator manufactured by TT Electronics/Optek Technology. It comprises an infrared emitting diode and an NPN silicon phototransistor housed in a hermetically sealed TO-78 metal can package. The device provides 1000VDC electrical isolation between input and output channels. Key electrical parameters include a maximum collector-emitter voltage of 35V, a forward current of 40mA, and a minimum current transfer ratio of 100% at 10mA. It features a base contact for transistor biasing and operates within a temperature range of -65°C to 125°C.

Feature Summary

Hermetically sealed TO-78 metal can package designed for military and harsh environments
High current transfer ratio with base contact provided for conventional transistor biasing
1 kV electrical isolation between input and output circuits

Applications

High-voltage isolation between input and output
Electrical isolation in dirty environments
Industrial equipment
Medical equipment
Office equipment

Procurement Notes

Verify the specific suffix 'U' against official manufacturer documentation, as standard datasheets typically list variants such as 'A', 'TX', or 'TXV'. Confirm that the component meets MIL-PRF-19500 processing requirements if intended for military applications. Ensure the hermetic seal integrity is validated for the specific batch. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when high reliability and environmental ruggedness are required. The TO-78 package offers superior protection compared to plastic packages. The base contact allows for improved switching speed control. Consider the operating temperature range and isolation voltage requirements. Verify compatibility with existing circuit designs regarding forward current and saturation voltage specifications.

Part Context

The 4N24AU belongs to the 4N22-24 series of optocouplers from TT Electronics/Optek Technology. This series is characterized by its use in demanding applications where standard plastic-packaged devices may fail. The hermetically sealed construction distinguishes it from commercial-grade alternatives, providing enhanced durability against moisture and contaminants.
