4N23ATXV

Overview

The 4N23ATXV is a high-reliability optically coupled isolator manufactured by TT Electronics. It integrates an infrared emitting diode and an NPN silicon phototransistor within a hermetically sealed TO-78 package. The device provides electrical isolation between input and output circuits, featuring a collector electrically isolated from the case as indicated by the 'A' suffix. Designed for military and harsh environments, it offers high current transfer ratio and 1 kV electrical isolation with a base contact for conventional transistor biasing.

Feature Summary

Hermetically sealed TO-78 package construction
High current transfer ratio performance
1 kV electrical isolation capability
Base contact provided for biasing

Applications

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

Procurement Notes

Verify that the specific part number matches the required configuration, particularly noting that the 'A' suffix denotes a collector isolated from the case. Confirm compliance with relevant military specifications such as MIL-PRF-19500 if screening options are required for your application environment. Ensure the hermetic seal integrity meets your operational standards.

Selection Notes

Select this component when high reliability and environmental ruggedness are critical requirements. The TO-78 package suits applications demanding superior protection against moisture and contaminants compared to standard plastic packages. Consider the base contact feature if external biasing control is necessary for the phototransistor operation in your circuit design.

Part Context

This device belongs to the 4N23 series of optocouplers produced by TT Electronics/Optek Technology. It is engineered specifically for defense and aerospace sectors where long-term stability and radiation hardness are often prioritized. The hermetic sealing distinguishes it from commercial-grade alternatives, ensuring consistent performance under extreme thermal and mechanical stress conditions.
