Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source, as Raytheon Company and Microsemi are also listed for this part number. Confirm that the JANTX suffix indicates qualified military specifications. Ensure the TO-46 package dimensions match the mechanical constraints of the target assembly. Validate the operating temperature range requirements against the specified -65°C to +200°C limits before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a hermetically sealed PNP transistor is required for high-reliability chopper applications. The TO-46 metal case provides superior thermal and physical protection compared to plastic packages. Consider the 35 V collector-emitter voltage rating to ensure it exceeds the maximum circuit potential. Verify that the 100 mA continuous current capability aligns with the load requirements.

Single Bipolar Transistors Part Context

This part belongs to the JANTX series of radiation-hardened or military-grade semiconductors produced by Microchip Technology. The JANTX designation typically signifies enhanced screening and qualification standards beyond commercial grades. The 2N2946A base model is a standard PNP small-signal transistor, while the JANTX variant ensures stricter parameter control and reliability for defense and aerospace use cases.
