Single Bipolar Transistors Procurement Notes

Verify the exact ordering suffix against the manufacturer's official datasheet to ensure compatibility with specific thermal or electrical variants. Confirm that the TO-126ML package designation matches your PCB footprint requirements. Cross-reference the part number with authorized distributors to guarantee authenticity and traceability. Check for any recent design changes or lifecycle status updates directly from onsemi documentation before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring a single NPN transistor with moderate current capacity and voltage ratings. Ensure the application does not exceed the 50 V collector-emitter breakdown limit or the 2.5 A current threshold. Consider the 1.5 W power dissipation rating relative to your thermal environment. This device is suitable for through-hole assembly processes where higher current handling than surface-mount alternatives is required.
