KSC945COTA

Single Bipolar Transistors Overview

The KSC945COTA is an NPN epitaxial silicon transistor manufactured by onsemi, housed in a TO-92-3 (CASE 135AN) lead-formed package. It features a center collector pinout configuration defined by the 'C' suffix. Key electrical ratings include a collector-base voltage of 60 V, collector-emitter voltage of 50 V, and emitter-base voltage of 5 V. The device supports a maximum continuous collector current of 150 mA with a power dissipation of 250 mW. It exhibits a typical current gain bandwidth product of 300 MHz and a DC current gain range of 120 to 240 at 1.0 mA.

Single Bipolar Transistors Procurement Notes

Verify component authenticity through authorized onsemi channels or certified distributors. Confirm the specific 'C' suffix indicates the center collector variant required for your design. Review the datasheet for absolute maximum ratings to ensure operational limits are not exceeded during implementation.

Single Bipolar Transistors Selection Notes

Select this component when a center collector topology is necessary for improved heat dissipation in TO-92 packages. Ensure the circuit requirements align with the 150 mA current limit and 250 mW power dissipation capabilities. Verify compatibility with the complementary KSA733 if push-pull configurations are utilized in the design.

Single Bipolar Transistors Part Context

This part belongs to the KSC945 series of NPN epitaxial transistors designed for general-purpose analog and switching applications. The series includes variants with different pinouts and packaging options, such as bulk and tape-and-reel formats. The C-series specifically addresses thermal performance needs through its central collector arrangement.

Single Bipolar Transistors Replacement Considerations

The KSA733 serves as the complementary PNP counterpart within the same family. For direct replacement, verify that the alternative component matches the center collector pinout and meets the 60 V VCBO and 150 mA IC specifications.
