KSB1097RTU

Single Bipolar Transistors Overview

The KSB1097RTU is a PNP epitaxial silicon transistor manufactured by onsemi, formerly Fairchild Semiconductor. It is housed in a TO-220F package and designed for low-frequency power amplifier and low-speed switching applications. The device features an absolute maximum collector-base voltage of -80 V, a collector-emitter voltage of -60 V, and a continuous collector current rating of -7 A. Thermal management allows for up to 30 W of collector dissipation at a case temperature of 25°C.

Single Bipolar Transistors Procurement Notes

Verify the specific RTU suffix against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Confirm that the component status aligns with current production availability, as datasheets may reflect legacy manufacturing phases from the original Fairchild Semiconductor era.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -60 V collector-emitter voltage and -7 A continuous current capability is required. Ensure the application operates within the specified junction temperature limits and utilizes adequate heat sinking to manage the thermal resistance associated with the TO-220F package during high-power operation.

Single Bipolar Transistors Part Context

This part belongs to the general-purpose power transistor category. It serves as a standard discrete semiconductor solution for medium-power switching tasks. The TO-220F package provides robust mechanical stability and efficient thermal transfer to external heatsinks, distinguishing it from smaller surface-mount alternatives.

Single Bipolar Transistors Replacement Considerations

The KSD1588 is documented as the complementary NPN counterpart. Verify pinout compatibility and electrical parameters before substituting with other PNP transistors offering similar voltage and current ratings.
