KSD2012YTU

Single Bipolar Transistors Overview

The KSD2012YTU is an NPN epitaxial silicon transistor manufactured by Fairchild Semiconductor, now part of ON Semiconductor. It is housed in a TO-220F-3 package and rated for a collector-emitter voltage (Vceo) of 60V and a continuous collector current (Ic) of 3A. The device is designed for low-frequency power amplifier applications. This component is classified as obsolete and is no longer in production.

Single Bipolar Transistors Feature Summary

• NPN epitaxial silicon construction
• TO-220F-3 through-hole package
• Designed for low-frequency power amplification

Single Bipolar Transistors Applications

• Low frequency power amplifier circuits
• General purpose switching applications
• Audio signal processing stages

Single Bipolar Transistors Procurement Notes

Verify availability carefully as the KSD2012YTU is officially listed as obsolete and not in production by the manufacturer. Sourcing may require checking secondary market distributors or considering direct replacements from ON Semiconductor's current portfolio. Confirm exact package pinout compatibility before integration into existing designs to ensure proper circuit functionality.

Single Bipolar Transistors Selection Notes

Select this component only if legacy design compatibility with the 60V, 3A NPN specification is strictly required. Evaluate thermal management capabilities inherent to the TO-220F-3 package for the intended load conditions. Consider modern equivalents from ON Semiconductor that offer improved performance metrics or updated manufacturing processes while maintaining similar electrical characteristics.

Single Bipolar Transistors Part Context

This transistor belongs to the KSD series of NPN power transistors originally developed by Fairchild Semiconductor. Following the acquisition of Fairchild by ON Semiconductor, product documentation and support have transitioned to the latter entity. The KSD2012YTU represents a specific variant within this lineage, characterized by its robust current handling and voltage ratings suitable for discrete power stages.

Single Bipolar Transistors Replacement Considerations

Consult ON Semiconductor datasheets for current NPN power transistors with comparable Vceo and Ic ratings. Verify pinout alignment between potential substitutes and the original TO-220F-3 footprint to prevent mechanical installation errors.
