JANTX2N3029

Overview

The JANTX2N3029 is a dual NPN bipolar junction transistor manufactured by Microchip Technology (formerly Microsemi). It is designed for high-reliability applications and meets the MIL-PRF-19500/115 specification. The device features a hermetically sealed glass passivated die within a TO-8 metal can package, providing robust performance in harsh environments. Key electrical characteristics include a collector-emitter voltage of 40V, a collector current of 1A, and a power dissipation rating of 1W. The component operates within a temperature range of -65°C to +200°C, ensuring stability under extreme thermal conditions.

Feature Summary

• Dual NPN configuration integrated into a single hermetically sealed unit
• Qualified to MIL-PRF-19500/115 military reliability standards
• Glass passivated die construction for enhanced environmental resistance
• Wide operating temperature range suitable for extreme conditions

Applications

• Military aerospace electronic systems requiring high reliability
• Harsh environment signal processing circuits
• High-temperature amplifier stages
• Radiation-hardened or screened electronic assemblies

Procurement Notes

Verify the specific screening level and lot traceability required for your application, as military-grade components often require adherence to source control drawings. Confirm that the supplier provides necessary documentation, including test reports and material certifications, to ensure compliance with procurement specifications. Due to the specialized nature of this component, lead times may vary significantly based on manufacturing schedules and availability.

Selection Notes

Select the JANTX2N3029 when a dual NPN transistor with high thermal stability and military-grade reliability is required. Ensure the design accommodates the TO-8 package dimensions and mounting requirements. Consider the 40V collector-emitter voltage and 1A current limits to verify suitability for the intended circuit load. Evaluate the need for hermetic sealing against environmental factors such as moisture and radiation exposure.

Part Context

This component belongs to the JAN series of transistors produced by Microchip Technology, which are qualified to military specifications. The JANTX designation indicates a higher screening level than standard JAN parts, offering improved consistency and reliability. These devices are part of a broader portfolio of discrete semiconductors designed for defense and aerospace applications where failure is not an option.

Replacement Considerations

Direct replacements must match the dual NPN configuration, TO-8 package, and MIL-PRF-19500/115 qualification. Verify pinout compatibility and electrical parameters such as VCEO, IC, and PD. Cross-reference with other JANTX2N3029 equivalents from authorized distributors to ensure identical screening levels and performance characteristics.
