Combo of NPN BD139 & PNP BD140 General Purpose Transistors 5 pcs Each

The combo of NPN BD139 and PNP BD140 general-purpose transistors is a practical and versatile set designed for a wide range of electronic applications. These complementary transistors are ideal for use in amplifiers, switching circuits, motor drivers, audio applications, and power regulators. Together, they provide a reliable solution for creating push-pull amplifier configurations and other circuits requiring both NPN and PNP transistor types. The BD139 (NPN) and BD140 (PNP) are medium-power transistors, each capable of handling collector currents up to 1.5A and voltages up to 80V. Their TO-126 package provides efficient heat dissipation and is well-suited for applications where moderate power handling and thermal stability are essential. These transistors feature high gain (hFE) and fast switching speeds, making them suitable for both linear and digital circuitry. This combo is especially useful for electronics hobbyists, engineers, and students working on analog circuits or prototyping general-purpose driver stages. Whether you're building a small amplifier or a discrete power switch, this NPN-PNP pair offers balanced and dependable performance.
