Single Bipolar Transistors Procurement Notes

Verify the current lifecycle status directly with Panasonic, as the datasheet indicates maintenance or discontinuation stages. Confirm that the specific order meets RoHS Directive compliance requirements. Ensure the application remains within standard general electronics use cases, avoiding special applications like aerospace or life support systems without prior consultation. Validate that thermal management solutions align with the specified junction temperature limits.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high voltage isolation up to 900 V collector-base and moderate current handling up to 3 A. Consider the TO-220F-A1 package dimensions for PCB layout and heatsink compatibility. Evaluate the 4 MHz transition frequency against the required switching speeds in the target application. Ensure the base drive circuit can supply sufficient current to achieve the specified saturation voltages.

Single Bipolar Transistors Part Context

This part belongs to the category of silicon NPN power transistors manufactured by Panasonic Electronic Components. It utilizes triple diffusion planar technology to achieve its performance specifications. The component is distinct from surface-mount resistors or capacitors often found in similar catalogs, serving specifically as a discrete semiconductor switch for power control applications.

Single Bipolar Transistors Replacement Considerations

Consult Panasonic sales staff for alternative parts if this model is discontinued. Verify pinout compatibility and absolute maximum ratings before substituting with other NPN power transistors. No specific substitute part numbers are confirmed in the provided documentation.
