2SB1201T-E

Single Bipolar Transistors Overview

The onsemi 2SB1201T-E is a single PNP bipolar junction transistor (BJT) designed for general-purpose switching applications. It features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 2 A. The device operates in a surface-mount TP-FA package, which corresponds to the TO-252-3 form factor. Key electrical parameters include a transition frequency of 150 MHz and a maximum power dissipation of 800 mW. The component supports a maximum junction temperature of 150°C and offers a minimum DC current gain of 140 at specified test conditions.

Single Bipolar Transistors Feature Summary

• High-speed switching capability with a transition frequency of 150 MHz
• Low saturation voltage for efficient power handling in switching circuits
• Robust thermal performance supporting operation up to 150°C junction temperature

Single Bipolar Transistors Applications

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'T-E' against official datasheets to confirm tape-and-reel packaging and compliance status. Confirm availability as this series may be subject to discontinuation notices. Ensure the selected variant matches the required TP-FA package dimensions for PCB layout compatibility.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a compact PNP switch with moderate current handling. The 150 MHz transition frequency makes it suitable for faster switching frequencies compared to standard low-frequency transistors. Consider the 800 mW power dissipation limit when designing thermal management solutions for the TO-252-3 package.

Single Bipolar Transistors Part Context

This part belongs to the 2SB1201 series of PNP bipolar transistors from onsemi. These devices are engineered for use in relay drivers and converters where small package size and fast switching are critical. The series emphasizes low saturation voltage and excellent linearity to support efficient circuit operation in industrial and consumer electronics.

Single Bipolar Transistors Replacement Considerations

Check for direct pin-compatible replacements within the same product family or equivalent PNP transistors with matching 50V/2A ratings. Verify that any substitute maintains the 150 MHz transition frequency and compatible package footprint.
