Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official documentation to ensure correct packaging and packing quantity. Confirm that the component meets RoHS requirements and check for any recent Fairchild Semiconductor integration updates regarding part nomenclature changes. Ensure compliance with all applicable safety standards before procurement.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring robust NPN switching or amplification within standard voltage limits. Consider the SOT-223 package for surface-mount assembly needs. Evaluate thermal resistance characteristics relative to the intended PCB layout to ensure adequate heat dissipation during operation.

Single Bipolar Transistors Part Context

This device belongs to the 2N3904 family of NPN transistors, originally developed by Fairchild Semiconductor and now managed by onsemi. It shares core electrical specifications with the TO-92 and SOT-23 variants but utilizes a distinct SOT-223 package to accommodate higher power dissipation capabilities in surface-mount configurations.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the MMBT3904 and 2N3904 series components. Verify pinout compatibility and package dimensions when transitioning between SOT-23, TO-92, and SOT-223 form factors.
