Single Bipolar Transistors Procurement Notes

Verify the specific radiation hardness level (JANSM, JANSD, etc.) required for the application against the datasheet. Confirm that the trailing /TR indicates tape and reel packaging if automated assembly is used. Ensure the procurement source provides traceability documentation compliant with MIL-PRF-19500 requirements.

Single Bipolar Transistors Selection Notes

Select this component when radiation tolerance and high-temperature operation are critical. Compare the specific radiation grade suffix against mission requirements. Verify that the UB package dimensions fit the PCB layout constraints. Ensure the 50V rating meets the circuit voltage headroom needs.

Single Bipolar Transistors Part Context

This part belongs to the 2N2222 family of NPN transistors adapted for harsh environments. It shares electrical characteristics with standard commercial variants but utilizes specialized processing to withstand ionizing radiation. The JAN prefix denotes a specific qualification level within the military-grade product line.

Single Bipolar Transistors Replacement Considerations

Direct replacements must match the radiation hardness specification. Standard commercial 2N2222 variants lack radiation tolerance and are unsuitable for this environment. Verify pinout compatibility with the UB package before substitution.
