The 2N3906 is a general-purpose PNP bipolar junction transistor designed for low-power switching and amplification applications. It supports a maximum collector-emitter voltage of 40 V and a continuous collector current of 200 mA, making it suitable for signal conditioning and control circuits. Typical uses include complementary amplifier stages, low-current drivers, and logic-level switching. The device is optimized for through-hole PCB mounting and maintains stable electrical performance across an operating temperature range of –55 °C to +150 °C.
