Single Bipolar Transistors Applications

• Aerospace electronic systems
• Military-grade switching circuits
• High-reliability signal processing

Single Bipolar Transistors Procurement Notes

Verify that the specific order includes the JANS suffix to ensure radiation hardness and hermetic sealing are present. Confirm compliance with the relevant agency specification, as it takes precedence over general datasheet information. Check for recent Product Change Notifications (PCNs) regarding manufacturing updates or material changes before finalizing procurement decisions.

Single Bipolar Transistors Selection Notes

Select this component when radiation tolerance and long-term reliability are critical requirements. Ensure the design accommodates the 500 mW power dissipation limit and the TO-18 metal package thermal characteristics. Verify that the 40 V collector-emitter voltage rating meets the circuit's peak operating conditions without exceeding safe limits.

Single Bipolar Transistors Part Context

This part belongs to the 2N2222 family of NPN transistors, specifically tailored for defense and space sectors. Unlike commercial variants, the JANS version undergoes rigorous screening and testing to meet military specifications. It serves as a robust alternative for general-purpose switching where standard components would fail due to radiation exposure or harsh environmental conditions.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other JANS-qualified versions of the 2N2222 from authorized manufacturers. Verify pinout compatibility and electrical parameter equivalence, particularly VCEO and hFE ranges, before substitution.
