2N5086 Pinout, Equivalent, Application, Datasheet

The 2N5086 pinout follows the Emitter–Base–Collector (E–B–C) configuration when the flat side of its TO-92 package is facing forward.
The 2N5086 PNP transistor is a high-gain, low-noise small-signal device designed for audio, RF, and general-purpose amplifier circuits.
It supports up to –100 mA collector current and –50 V collector-emitter voltage, making it ideal for precision low-current amplification, analog signal control, and switching applications in compact electronic designs.

Because of its low noise figure, stable gain, and wide frequency response, the 2N5086 is a preferred transistor in microphone preamps, tone control stages, and high-fidelity amplifier modules.

Introduction to 2N5086 PNP Transistor

The 2N5086 transistor is a silicon planar PNP bipolar junction transistor (BJT) built to operate efficiently in low-power analog signal circuits.
It is often used where clean signal amplification, temperature stability, and low distortion are essential.

With a DC current gain (hFE) typically between 200 and 600, it provides a smooth and linear amplification curve, making it well-suited for audio driver circuits and sensor signal processing.
Its TO-92 encapsulation offers easy integration into PCBs, breadboards, and small electronic modules.

Working Principle of 2N5086 PNP Transistor

In a 2N5086 transistor, a small base current controls a much larger emitter-to-collector current flow.
When the base terminal is biased negative relative to the emitter, the transistor enters its active region, amplifying the input signal.
When the base is more negative than the emitter by about 0.7 V, the device conducts, enabling current transfer through the collector.

This property allows the 2N5086 to function as a precise analog amplifier, or as an efficient low-power electronic switch in digital circuits.
