Procurement Notes

Verify the specific suffix 'E-S' against official manufacturer documentation to confirm exact binning or packaging variations. Confirm RoHS compliance status as datasheets may vary by production batch. Ensure the TO-220-3 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring robust NPN switching or amplification with moderate voltage handling. The 40 W power dissipation rating necessitates adequate thermal management solutions. Verify that the 60 V collector-emitter voltage meets the circuit's peak operating conditions. Consider the 3 A continuous current limit when designing load paths.
