KSE2955TTU

Single Bipolar Transistors Overview

The KSE2955TTU is a PNP silicon epitaxial planar transistor manufactured by onsemi, originally designed by Fairchild Semiconductor. It is housed in a TO-220 package and rated for a maximum collector current of 10 A and a collector-emitter voltage of -60 V. The device features a collector-base voltage of -70 V and an emitter-base voltage of -5 V. Power dissipation reaches 75 W at case temperatures of 25°C. The DC current gain ranges from 5 to 100 at 10 A, with a minimum current gain bandwidth product of 2 MHz.

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin carefully, as the component was originally produced by Fairchild Semiconductor before its semiconductor division acquisition. Confirm that the specific ordering suffix matches the required package variant and compliance standards. Ensure the datasheet revision aligns with your design requirements, noting that specifications may have been updated during corporate transitions.

Single Bipolar Transistors Selection Notes

Select this component when a robust PNP transistor capable of handling 10 A continuous current is required in a through-hole TO-220 form factor. Consider the thermal management capabilities, as power dissipation drops significantly without adequate heatsinking. Compare against other PNP transistors in the same voltage class if lower saturation voltages or different packaging options are needed for the specific application constraints.

Single Bipolar Transistors Part Context

This part belongs to the broader family of high-current PNP bipolar junction transistors used in power electronics. It shares functional similarities with other legacy components like the MJ2955 and MJE2955 series, though physical dimensions and exact electrical parameters vary. These devices are commonly found in industrial control systems and audio equipment where reliable high-current switching is essential.
