KSC945LTA

Single Bipolar Transistors Overview

The KSC945LTA is an NPN epitaxial silicon transistor manufactured by onsemi, housed in a TO-92-3 (CASE 135AR) through-hole package. It features a collector-base voltage of 60 V, a collector-emitter voltage of 50 V, and a maximum collector current of 150 mA. The device provides a typical high current gain bandwidth product of 300 MHz and a power dissipation rating of 250 mW at 25°C ambient temperature.

Single Bipolar Transistors Feature Summary

• Designed for audio frequency amplifier applications
• High current gain bandwidth product suitable for high-frequency oscillators
• Complementary to the KSA733 PNP transistor

Single Bipolar Transistors Applications

• Audio frequency amplifiers
• High-frequency oscillators

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'LTA' against official documentation, as standard datasheets list variants such as YTA, CYTA, and YBU. Confirm availability status, as some KSC945 series packages are discontinued or not recommended for new designs. Ensure compliance with RoHS requirements if applicable to the specific manufacturing lot.

Single Bipolar Transistors Selection Notes

Select this component for low-power NPN switching and amplification tasks requiring moderate voltage ratings. Consider the complementary KSA733 for push-pull configurations. Validate thermal management capabilities given the 250 mW dissipation limit and junction-to-ambient thermal resistance characteristics.

Single Bipolar Transistors Part Context

This part belongs to the KSC945 family of NPN epitaxial silicon transistors. The series is characterized by high breakdown voltages and linear current gain performance. Variants within the family differ primarily in packaging styles and lead configurations, such as kinked leads or center collector arrangements.

Single Bipolar Transistors Replacement Considerations

The KSA733 serves as the complementary PNP counterpart. Verify pinout compatibility when substituting with other TO-92 NPN transistors having similar voltage and current ratings.
