KSB772YSTU

Single Bipolar Transistors Overview

The KSB772YSTU is a PNP bipolar junction transistor manufactured by onsemi. It features a maximum collector-emitter voltage of 30 V and a continuous collector current rating of 3 A. The device operates in a TO-126-3 package with a maximum power dissipation of 1 W. Key electrical characteristics include a DC current gain (hFE) of at least 160 at 1 A, a transition frequency of 80 MHz, and a collector cutoff current of 1 µA. The component supports a maximum junction temperature of 150°C.

Single Bipolar Transistors Feature Summary

• PNP polarity configuration for single-transistor applications
• Through-hole mounting capability via TO-126-3 package
• High DC current gain performance at elevated currents
• Operational stability up to 150°C junction temperature

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Low-voltage power regulation stages
• Amplifier output stages requiring PNP topology

Single Bipolar Transistors Procurement Notes

Verify the exact suffix 'YSTU' against official manufacturer documentation, as standard listings typically reference 'KSB772YS'. Confirm RoHS compliance status and REACH registration details directly from the datasheet. Ensure the TO-126-3 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Single Bipolar Transistors Selection Notes

Select this component when a PNP BJT with 3 A current handling and 30 V breakdown is required in a through-hole format. Compare the 80 MHz transition frequency against circuit speed needs. Evaluate the 1 W power dissipation limit relative to thermal management constraints in the target application environment.

Single Bipolar Transistors Part Context

This part belongs to the KSB772 series of PNP transistors designed for general-purpose use. It serves as a replacement for older STMicroelectronics 2SB772 devices. The series is characterized by robust current handling and moderate frequency response suitable for standard electronic control and power management tasks.

Single Bipolar Transistors Replacement Considerations

The KSB772YS is the primary verified equivalent listed by distributors. Verify pinout compatibility and thermal resistance values when substituting with other PNP transitors in the same voltage and current class.
