Single Bipolar Transistors Procurement Notes

Verify the specific radiation hardness level and qualification standards required for your application against the official datasheet specifications. Confirm that the UA surface-mount package aligns with your PCB design constraints. Ensure compliance with environmental regulations such as RoHS status as documented in the product compliance files provided by the manufacturer.

Single Bipolar Transistors Selection Notes

Select this component when radiation tolerance is a critical requirement for NPN switching or amplification tasks. Compare the 50 V collector-emitter voltage and 800 mA current limits against circuit demands. Consider the extended operating temperature range up to 200 °C for high-thermal-stress scenarios. Verify compatibility with surface-mount assembly processes due to the UA package type.

Single Bipolar Transistors Part Context

This part belongs to the 2N2222 family of NPN transistors but is distinguished by its radiation-hardened design and specific surface-mount packaging. Unlike standard commercial variants, it is engineered for enhanced durability in aerospace and defense contexts. The TR suffix indicates reel packaging for automated surface-mount technology assembly.
