2SA2169-TL-E is classified under transistors - bipolar (BJT) - single, and has a range of application fields. It is a PNP type epitaxial planar silicon transistor, which is most often used for driver and output applications. This transistor is generally better-suited to low-frequency applications since it has a lower fT (frequency of transition) compared to many other transistors.

This single transistor is designed to meet both general and specific requirements of applications, and consists of a P-type silicon substrate, N-type collector region, N-type emitter region and a P-type base region. A n–p–n junction is formed at the base–collector junction and a p–n–p junction is formed at the emitter–base junction.

2SA2169-TL-E employs 2 SOT-223 Transistor Outline, having Drain, Gate and Source connections, and it use a single diffused shield between Gate and Source connections. This transistor is particularly well aligned for applications such as voltage regulators, TV and radio receivers, modulation, remote control circuits, audio amplifiers, switching circuits, sine wave generators and high frequency amplifiers.

Working Principle

2SA2169-TL-E transistor works based on the principle of a p–n–p junction. This construction allows it to be normally conducting, but biased so that it will become non-conducting, resulting in an open circuit condition. Depending on its use, the 2SA2169-TL-E can be biased in the cut-off region or the active region.

When it is in the active region, a small base current allows a very large collector current to flow. The amount of current flowing through the collector is largely independent of the base current, allowing it to be used in an ‘amplifying’ mode.

In the cut-off region, the transistor is non-conducting and does not allow significant amounts of current to flow. This makes it a convenient way to switch other electronic components or circuits. The 2SA2169-TL-EI can also be used as an inverting or non-inverting amplifier depending on how it is biased in the active region.
