2N2222AUBTXV

Single Bipolar Transistors Overview

The 2N2222AUBTXV is a hermetically sealed, miniature NPN general-purpose switching transistor manufactured by TT Electronics/Optek Technology. It utilizes a three-terminal ceramic surface mount package (UBN) designed to minimize circuit board area while providing military reliability levels. The device features a maximum collector current of 800 mA and a collector-emitter breakdown voltage of 50 V. Power dissipation is rated at 300 mW or 500 mW depending on specific datasheet revisions. Operating temperature ranges from -65°C to +200°C. The component is processed per MIL-PRF-19500/255 standards.

Single Bipolar Transistors Feature Summary

• Hermetically sealed in a miniature three-pin ceramic surface mount package for enhanced environmental protection.
• Processed according to MIL-PRF-19500/255 specifications for high reliability applications.
• Includes 100% thermal response testing for the TXV suffix variant.
• Compatible footprint with many SOT-23 package transistors for easy upgrading.

Single Bipolar Transistors Applications

• General purpose switching circuits requiring military-grade reliability.
• Upgrading commercial grade plastic SOT-23 circuits to higher reliability levels.
• Signal processing and amplification in harsh environments.

Single Bipolar Transistors Procurement Notes

Verify the specific revision level of the datasheet when ordering, as power dissipation ratings may vary between 300 mW and 500 mW depending on the manufacturing batch. Confirm that the TXV suffix is required if thermal response testing is necessary for the application. Ensure compatibility with the UBN ceramic package dimensions during PCB layout. Check RoHS compliance status as some variants may not meet current environmental directives.

Single Bipolar Transistors Selection Notes

Select this component when replacing standard plastic transistors with hermetically sealed equivalents for critical systems. The UBN package offers a direct footprint replacement for many SOT-23 devices. Consider the wide operating temperature range suitable for extreme conditions. Verify the DC current gain requirements against the minimum specifications provided in the official documentation before finalizing the design.

Single Bipolar Transistors Part Context

This part belongs to the 2N2222 family of NPN silicon transistors produced by TT Electronics/Optek Technology under the Optek brand. The 'UB' designation refers to the specific three-terminal chip carrier package style. The 'TXV' suffix indicates additional screening and thermal testing beyond the standard MIL-PRF-19500/255 process. It serves as a high-reliability alternative to commercial grade small-signal transistors.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other hermetically sealed NPN transistors meeting MIL-PRF-19500/255 specifications. Verify pinout compatibility with the original SOT-23 or UB package footprint. Ensure voltage and current ratings match or exceed the original design requirements. Consult manufacturer cross-reference lists for equivalent parts from other qualified suppliers.
