Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'QR' against the official Nexperia datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the ordering part number matches the required tolerance and thermal characteristics. Cross-reference the manufacturer's latest documentation to confirm availability status and any potential obsolescence notices before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN switch with integrated biasing is required. The built-in resistors reduce board space and assembly costs compared to discrete resistor-transistor combinations. Verify that the 50 V collector-emitter voltage and 100 mA current limits meet the application's electrical requirements. Consider the SOT-23 package constraints for thermal management and PCB layout.

Single Bipolar Transistors Part Context

This part belongs to Nexperia's portfolio of digital transistors, which combine bipolar transistors with on-chip resistors.
