KSH44H11TF

Single Bipolar Transistors Overview

The KSH44H11TF is an NPN epitaxial silicon transistor manufactured by onsemi. It features a TO-252-3 (DPAK) surface-mount package with leads formed for mounting. The device supports a collector-emitter voltage of 80 V and a continuous DC collector current of 8 A, with a peak pulse current rating of 16 A. Power dissipation reaches 20 W at a case temperature of 25°C and 1.75 W at an ambient temperature of 25°C. The junction temperature maximum is 150°C. Electrical characteristics include a minimum DC current gain of 40 to 60, a saturation voltage of 1 V at 8 A, and a transition frequency of 50 MHz.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and packing method. The 'TF' suffix indicates a Tape and Reel configuration in the TO-252 3L (DPAK) package. Confirm that the component meets all applicable RoHS and REACH requirements before integration into final designs.

Single Bipolar Transistors Selection Notes

Select this component when a surface-mount NPN power transistor is required for high-current switching applications. Ensure the thermal management design accommodates the specified power dissipation limits at the intended operating temperature. Verify that the 80 V collector-emitter voltage rating exceeds the maximum circuit voltage under all operating conditions.

Single Bipolar Transistors Part Context
