JANTX2N2919L

Overview

The JANTX2N2919L is a dual small-signal NPN bipolar junction transistor manufactured by Microchip Technology. It features an integrated common-base configuration with two separate transistors housed in a single package. The device utilizes silicon planar technology and is designed for high-reliability applications requiring radiation hardness. Key electrical parameters include a collector-emitter voltage of 60V, a collector current of 30mA, and a power dissipation of 350mW. It operates within a temperature range of -65°C to +200°C and is available in surface-mount SQ packages.

Feature Summary

• Dual NPN configuration providing two independent transistors in one component
• Radiation-hardened design suitable for harsh environments
• High-temperature operation capability up to 200°C
• Silicon planar technology for consistent performance

Applications

• Aerospace and satellite electronic systems
• Military communication equipment
• High-reliability signal processing circuits
• Harsh environment sensor interfaces

Procurement Notes

Verify the specific suffix 'L' against official Microchip documentation to confirm package type and testing level. Ensure compliance with project radiation hardness requirements. Confirm availability through authorized distributors as lead times may vary for military-grade components.

Selection Notes

Select this component when a dual NPN configuration is required in a compact surface-mount form factor. Consider the 60V rating and 30mA current limit for low-power switching or amplification tasks. Verify thermal management capabilities given the 350mW dissipation limit in the specified package.

Part Context

This part belongs to the JAN series of radiation-hardened semiconductors produced by Microchip. The JAN designation indicates compliance with military specifications. The 2N2919 family typically offers matched characteristics for differential applications. The 'TX' prefix often denotes enhanced testing levels beyond standard military grades.

Replacement Considerations

Check for direct equivalents such as JAN2N2919 or JAN2N2919U depending on package requirements. Verify pinout compatibility and electrical parameter overlaps before substitution. Consult Microchip's cross-reference tools for qualified alternatives.
