Single Bipolar Transistors datasheet and documents for 2SB0951AQ

2SB0951AQ

Single Bipolar Transistors Overview

The Panasonic 2SB0951 is a silicon PNP epitaxial planar type Darlington transistor designed for medium-speed switching applications. It serves as the complementary device to the 2SD1277 and 2SD1277A NPN transistors. The component is available in two voltage variants: the 2SB0951 rated at -60V collector-emitter voltage, and the 2SB0951A rated at -80V. Both models support a continuous collector current of -8A with a peak current capability of -12A. The package allows direct mounting to a heat sink using a single screw.

Single Bipolar Transistors Feature Summary

High forward current transfer ratio (hFE) for efficient drive requirements
Optimized for high-speed switching operations
Full-pack package design enabling secure heat sink installation via a single screw

Single Bipolar Transistors Applications

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

Single Bipolar Transistors Procurement Notes

Verify the specific voltage rating required for your application before ordering. The 2SB0951 is rated for -60V, while the 2SB0951A is rated for -80V. Confirm that the pinout matches the TO-220F-A1 or EIAJ SC-67 package dimensions. Ensure thermal management strategies align with the specified power dissipation curves under your expected ambient temperature conditions.

Single Bipolar Transistors Selection Notes

Select the 2SB0951A variant if the circuit requires a higher collector-emitter breakdown voltage of -80V compared to the standard -60V rating. Consider the transition frequency of 20 MHz when evaluating suitability for the intended switching speed. Verify that the base drive current can achieve the necessary hFE rank for the target collector current load.

Single Bipolar Transistors Part Context

This component belongs to the family of silicon PNP Darlington transistors manufactured by Panasonic Electronic Components. It is specifically engineered to complement the 2SD1277 and 2SD1277A NPN counterparts, facilitating push-pull or bridge configurations in power switching stages.
