JAN2N2905AL

Single Bipolar Transistors Overview

The JAN2N2905AL is a military-qualified PNP silicon switching transistor manufactured by Microchip Technology. It belongs to the 2N2904/2905 family and is qualified per MIL-PRF-19500/290 for high-reliability applications. The device features a maximum collector current of 600 mA, a collector-emitter breakdown voltage of 60 V, and a power dissipation rating of 800 mW. It utilizes a TO-39 (TO-205AD) metal can package with through-hole mounting. The component supports an extended junction temperature range from -65°C to +200°C.

Single Bipolar Transistors Feature Summary

• Military qualification compliant with MIL-PRF-19500/290 standards for high-reliability environments
• High thermal stability supporting junction temperatures up to 200°C
• Robust switching capability with 600 mA continuous collector current
• Metal can construction providing enhanced environmental protection

Single Bipolar Transistors Applications

• High-reliability aerospace systems
• Military-grade switching circuits
• Harsh environment signal processing
• Defense electronics requiring JANS level qualification

Single Bipolar Transistors Procurement Notes

Verify the specific suffix AL against official Microchip documentation to confirm exact binning or screening levels. Ensure procurement channels are authorized to prevent counterfeit components. Confirm that the MIL-PRF-19500/290 qualification status matches project requirements. Validate package integrity upon receipt due to the sensitive metal can construction.

Single Bipolar Transistors Selection Notes

Select this component when military reliability standards are mandatory. Compare against standard commercial variants if cost is a primary constraint and harsh environment operation is not required. Verify that the TO-39 package fits the mechanical design constraints. Consider the 800 mW power dissipation limit during thermal management planning.

Single Bipolar Transistors Part Context

This part is part of the broader 2N2904/2905 series of PNP switching transistors. While the standard 2N2905A offers similar electrical characteristics, the JAN prefix denotes specific military screening and qualification processes. This distinguishes it from commercial grade equivalents and ensures consistency in performance under extreme conditions.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other military-qualified versions within the same MIL-PRF-19500/290 specification. Verify pinout compatibility with the TO-39 package before substitution. Commercial equivalents like the standard 2N2905A lack the required military screening and should only be used if reliability standards permit.
