2SB09510P

Single Bipolar Transistors Overview

The Panasonic 2SB09510P is a silicon PNP epitaxial planar type darlington power transistor designed for medium-speed switching applications. It features a TO-220F-A1 package with an isolated collector terminal, allowing direct heat sink mounting via a single screw. The device supports a maximum collector current of -8A and peak currents up to -12A. Electrical ratings include a collector-emitter voltage of -60V for the standard variant and -80V for the 'A' suffix version. It operates within a junction temperature range up to 150°C and complies with RoHS directives.

Single Bipolar Transistors Feature Summary

• Darlington configuration providing high forward current transfer ratio
• Optimized for medium-speed switching operations
• Full-pack design enabling secure heat sink installation with one screw

Single Bipolar Transistors Applications

• Medium-speed switching circuits
• Complementary pairing with 2SD1277 series transistors
• General electronic equipment requiring high current gain

Single Bipolar Transistors Procurement Notes

Verify the specific voltage rating required for your application, as the base model supports -60V while the 'A' variant supports -80V. Confirm that the TO-220F-A1 package dimensions align with your thermal management design. Ensure compliance with the manufacturer's guidelines regarding absolute maximum ratings during transient states such as power-on or mode-switching to prevent device failure.

Single Bipolar Transistors Selection Notes

Select this component when high current gain and medium-speed switching are prioritized over ultra-high frequency performance. The darlington structure necessitates higher saturation voltages compared to single-transistor designs; verify that the resulting VCE(sat) meets your circuit efficiency requirements. Consider the complementary 2SD1277 if a matched push-pull configuration is needed for your amplifier or driver stage.

Single Bipolar Transistors Part Context

This part belongs to the 2SB0951 series of silicon PNP darlington transistors manufactured by Panasonic Electronic Components. It is specifically engineered as a complementary pair to the NPN 2SD1277 series, facilitating balanced design in power switching stages. The product line utilizes an epitaxial planar process to ensure stable characteristics across the specified operating temperature range.

Single Bipolar Transistors Replacement Considerations

Direct substitutes must match the PNP darlington topology and TO-220F-A1 package. Verify that any replacement maintains equivalent hFE ranks and thermal resistance characteristics. Cross-reference with the official Panasonic database for updated lifecycle status, as maintenance or discontinuation notices may affect long-term availability.
