Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix when purchasing. The 'PBFREE' designation indicates lead-free plating compliance. Requesting tin/lead plated devices requires adding the 'TIN/LEAD' suffix to the part number during the order process. Confirm mechanical outline compatibility with existing PCB footprints or chassis mounts before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high reliability and thermal stability due to its metal can packaging. Ensure the circuit operates within the 40 V collector-emitter voltage limit and 0.7 A continuous current threshold. Consider the 5.0 W power dissipation rating and required heat sinking based on ambient temperature conditions to maintain safe junction temperatures.

Single Bipolar Transistors Part Context
