KSH3055ITU

Single Bipolar Transistors Overview

The KSH3055ITU is an NPN epitaxial silicon transistor manufactured by onsemi, formerly Fairchild Semiconductor. It features a collector-emitter voltage of 60 V and supports a continuous collector current of 10 A. The device provides a DC current gain (hFE) ranging from 20 to 100 at 4 A and 5 to 100 at 10 A. Its current gain bandwidth product is 2 MHz minimum at 500 mA. Thermal ratings include a junction temperature up to 150 °C and power dissipation of 1.75 W at 25 °C ambient or 20 W at 25 °C case temperature. It utilizes the I-PAK package with straight leads.

Single Bipolar Transistors Procurement Notes

Verify the exact part number against official documentation, as legacy Fairchild nomenclature may differ from current ON Semiconductor listings due to system integration updates. Confirm that the suffix 'I' corresponds to the I-PAK package with straight leads rather than surface mount configurations. Ensure compliance with RoHS standards if required for the specific manufacturing environment.

Single Bipolar Transistors Selection Notes

Select this component when a robust NPN power transistor is needed for moderate frequency switching or linear amplification. The I-PAK package facilitates through-hole mounting, which is advantageous for designs requiring mechanical stability or manual assembly. Consider the thermal derating curves carefully, as power dissipation drops significantly above 25 °C ambient temperature.

Single Bipolar Transistors Part Context

This device belongs to the KSH3055 series of NPN power transistors. It is electrically similar to the KSE3055T model but distinguished by its specific lead configuration. The component represents a transition point in manufacturer history, originally released under Fairchild Semiconductor branding before being integrated into the ON Semiconductor portfolio.

Single Bipolar Transistors Replacement Considerations

The datasheet notes electrical similarity to the KSE3055T. Verify pinout compatibility and package dimensions before substitution. No other direct substitute part numbers are explicitly confirmed in the provided documentation.
