2N5680 Pinout, Equivalent, Application, Datasheet

The 2N5680 pinout describes a high-voltage PNP silicon transistor designed for RF, audio, and medium-power amplifier circuits. It is housed in a TO-39 metal can package with the Emitter–Base–Collector (E–B–C) configuration. This transistor operates efficiently in high-voltage and high-frequency environments, offering reliability and strong linear performance across analog and power stages.

The 2N5680 is frequently used in audio output drivers, radio-frequency power amplifiers, and voltage regulator circuits where stability, gain consistency, and thermal strength are essential.

Introduction to 2N5680 PNP Transistor

The 2N5680 is a PNP power transistor engineered for linear amplification and switching applications requiring moderate current handling and high-voltage tolerance. It supports up to –120V collector-emitter voltage (Vce) and –120V collector-base voltage (Vcb), delivering a collector current (Ic) of 1A with a total power dissipation (Ptot) of 10W.

Due to its low leakage, high breakdown voltage, and excellent gain stability, the 2N5680 is ideal for audio frequency amplifiers, signal drivers, and regulated power supply stages. Understanding the 2N5680 pinout ensures proper biasing and connection in amplifier or switching circuits.
