Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer origin, as the 2N3905TF designation may be distributed by various semiconductor companies including Fairchild or onsemi. Confirm that the ordering suffix 'TF' corresponds to the required tape and reel packaging format rather than bulk quantities. Ensure compliance with RoHS directives if applicable to the specific production lot.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a 40V collector-emitter breakdown voltage is required. It is appropriate for designs needing a continuous collector current of 200 mA and a maximum power dissipation of 625 mW. Consider the thermal resistance characteristics for heat management in enclosed environments.
