Single Bipolar Transistors Procurement Notes

Verify that the component explicitly bears the JANTX suffix to confirm it meets the specific quality and screening requirements defined in the MIL-S-19500/368C standard. Ensure the manufacturer documentation confirms the part is a silicon NPN BJT. Cross-reference the manufacturer's latest datasheet to validate current production status and any potential product change notifications affecting specifications or packaging.

Single Bipolar Transistors Selection Notes

Select this component when a design requires an NPN transistor capable of handling 350V collector-emitter voltage and 1A current with low power dissipation constraints. The JANTX designation indicates enhanced screening compared to commercial grades, making it appropriate for aerospace or defense projects where long-term reliability under stress is critical. Verify package compatibility during integration.

Single Bipolar Transistors Part Context

This device belongs to the 2N3439 family of NPN silicon transistors produced under military specifications. The JANTX variant represents a screened subset intended for higher reliability applications than standard commercial equivalents. It shares core electrical characteristics with other members of the series but adheres to stricter manufacturing controls outlined in the relevant military standard documents.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include JAN2N3439 and JANS2N3439, which share the same base electrical profile but differ in screening levels. Commercial equivalents like 2N3439 may match electrical ratings but lack the required military qualification data.
