2N3906 is a PNP bipolar junction transistor (BJT) that is commonly used as a switching or amplification device in electronic circuits. It is a low-power transistor that is widely available and affordable.
The 2N3906 transistor has a maximum collector-emitter voltage rating of 40V and a maximum collector current rating of 200mA. It is available in various through-hole packages, including the popular TO-92 package.
Because of its low-power rating and low-frequency response, the 2N3906 transistor is typically used in low-power switching and amplification applications, such as in small audio amplifiers, voltage regulators, and signal processing circuits.
When using the 2N3906 transistor or any other BJT in a circuit, it's important to pay attention to its pinout and operating parameters to ensure that it is properly biased and operates within its safe operating limits.
