KSH45H11TF

Single Bipolar Transistors Overview

The KSH45H11TF is a PNP epitaxial silicon transistor manufactured by onsemi, housed in a TO-252 (DPAK) surface-mount package. It supports a collector-emitter voltage of -80 V and a continuous DC collector current of -8 A. The device features a low collector-emitter saturation voltage of -1 V at -8 A and a current gain bandwidth product of 40 MHz. Thermal management allows for 20 W power dissipation at a case temperature of 25°C, with a maximum junction temperature of +150°C.

Single Bipolar Transistors Feature Summary

• Designed for fast switching speeds suitable for high-frequency applications
• Features low collector-emitter saturation voltage to minimize conduction losses
• Electrically similar to the popular KSE45H series for direct compatibility

Single Bipolar Transistors Applications

Single Bipolar Transistors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to industry counterfeiting risks. Confirm that the specific ordering suffix matches the required tape and reel packaging format. Ensure compliance with RoHS directives and check for any recent Fairchild Semiconductor integration updates regarding part nomenclature changes before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with an 8 A current rating and 80 V breakdown voltage is required in a DPAK package. Consider its 40 MHz transition frequency for switching speed requirements. Evaluate thermal derating curves if operating above 25°C ambient conditions. Verify suitability against the absolute maximum ratings to prevent overstress damage during transient events.

Single Bipolar Transistors Part Context

This device belongs to the KSH45H11 family of general-purpose power transistors originally developed by Fairchild Semiconductor.
