Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'S' against the manufacturer's official documentation to confirm exact packaging and compliance status. Confirm that the TO-218-3 package dimensions match the target PCB footprint requirements. Ensure the operating temperature range aligns with the thermal management design of the final assembly.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN switch is required alongside a complementary PNP device from the BDW84 family. Consider the 15 A continuous collector current limit and the 120 V breakdown voltage as primary constraints. Evaluate the thermal resistance of the TO-218-3 package for adequate heat dissipation in the intended application environment.
