JANS2N2904

Single Bipolar Transistors Overview

The JANS2N2904 is a PNP silicon switching transistor manufactured by Microchip Technology. It is designed for high-reliability applications and is qualified to the JANS level under MIL-PRF-19500/290. The device features a maximum collector-emitter voltage of 60 V and a continuous collector current of 600 mA. Power dissipation is rated at 800 mW in a TO-5 metal can package. Operating temperatures range from -65°C to +200°C junction temperature.

Single Bipolar Transistors Feature Summary

• Qualified to the JANS level for high-reliability space applications per MIL-PRF-19500/290
• Utilizes a hermetically sealed TO-5 metal can package for environmental protection
• Engineered as a PNP silicon switching transistor with defined DC current gain characteristics

Single Bipolar Transistors Applications

• Military aerospace systems requiring radiation-hardened or high-reliability components
• Spacecraft electronic subsystems subject to extreme thermal environments
• High-reliability industrial control circuits operating within specified temperature ranges

Single Bipolar Transistors Procurement Notes

Verify that the specific order includes the JANS qualification suffix, as this denotes the required military reliability standard. Confirm package integrity upon receipt, as the TO-5 metal can requires careful handling to maintain hermetic seal standards. Ensure storage conditions comply with manufacturer guidelines for sensitive semiconductor devices prior to assembly.

Single Bipolar Transistors Selection Notes

Select this component when design requirements mandate compliance with MIL-PRF-19500/290 JANS standards. It serves as a direct replacement for commercial variants like the 2N2904A where higher reliability is critical. Consider the TO-5 package constraints for PCB layout and thermal management strategies during the initial design phase.

Single Bipolar Transistors Part Context

This part belongs to the 2N2904 family of PNP switching transistors produced by Microchip Technology. While commercial versions exist in various packages, the JANS variant specifically targets defense and space sectors. It shares electrical similarities with other members but differs in manufacturing controls and testing protocols to meet stringent military specifications.
