2N5339U3

Overview

The Microchip Technology 2N5339U3 is a military-grade NPN silicon epitaxial planar transistor housed in the TO-39 (TO-205AD) metal can package. It is designed for high-reliability applications requiring robust performance under extreme conditions. Key electrical specifications include a maximum collector-emitter voltage of 100 V and a continuous collector current rating of 5 A. The device supports a maximum power dissipation of 1 W and operates within a junction temperature range of -65°C to +200°C. It meets the MIL-PRF-19500/560 qualification standard, ensuring suitability for demanding aerospace and defense environments.

Feature Summary

• Military-grade reliability compliant with MIL-PRF-19500/560 standards
• High thermal stability supporting extended junction temperatures up to 200°C
• Robust construction utilizing a hermetically sealed metal can package

Applications

• Aerospace and defense electronic systems
• High-reliability switching circuits
• Harsh environment amplifier stages

Procurement Notes

Verify that the specific suffix U3 corresponds to the intended military qualification level and packaging variant. Confirm compliance with relevant export control classifications such as EAR99. Ensure that procurement channels provide appropriate traceability documentation required for mission-critical hardware integration.

Selection Notes

Select this component when design requirements mandate high voltage handling and significant current capacity within a ruggedized form factor. The wide operating temperature range makes it suitable for environments where standard commercial grade devices would fail. Consider the through-hole mounting style and metal package thermal characteristics during PCB layout.

Part Context

This part belongs to the established 2N5339 family of NPN power transistors manufactured by Microchip Technology. The series is recognized for its durability in critical infrastructure and military applications. The U3 designation typically indicates specific manufacturing lot or packaging variations within the broader qualified product line.

Replacement Considerations

Direct replacements must match the TO-39 metal can footprint and meet identical MIL-PRF-19500/560 specifications. Verify that substitute parts maintain the same 100V breakdown voltage and 5A current ratings to ensure circuit compatibility.
