KSD569YTU

Single Bipolar Transistors Overview

The KSD569YTU is an NPN epitaxial silicon power transistor manufactured by onsemi, formerly Fairchild Semiconductor. It features a collector-emitter voltage of 80V and a continuous collector current rating of 7A. The device is housed in a TO-220 package with a maximum collector dissipation of 40W at 25°C case temperature. Key electrical characteristics include a DC current gain (hFE) ranging from 40 to 200 depending on the classification code, a collector-emitter saturation voltage of 0.5V maximum at 5A, and a junction temperature limit of 150°C.

• Industrial use applications

Single Bipolar Transistors Procurement Notes

Verify the specific hFE classification suffix (R, O, Y, or Z) required for the target circuit's gain requirements. Confirm that the TO-220 mounting configuration aligns with the thermal management design. Ensure the operating conditions remain within the absolute maximum ratings specified in the datasheet to maintain reliability.

Single Bipolar Transistors Selection Notes

Select this component when an NPN power transistor with 80V breakdown and 7A current capability is needed. Consider the hFE classification codes to match the necessary drive current levels. Evaluate the thermal resistance and heat sinking requirements based on the 40W dissipation rating at the case temperature.

Single Bipolar Transistors Part Context

This part belongs to the KSD568/569 family of NPN epitaxial silicon transistors originally produced by Fairchild Semiconductor. The KSD569 variant specifically provides an 80V collector-emitter voltage rating, distinguishing it from the 60V KSD568 model. Both share identical physical packaging and general electrical performance profiles.

Single Bipolar Transistors Replacement Considerations

The KSD568 serves as a lower voltage alternative within the same family. Designers should verify pinout compatibility and thermal characteristics when substituting with other NPN power transistors offering similar voltage and current ratings.
