The 2N3906 is a widely used PNP bipolar junction transistor (BJT) with a maximum collector current rating of 200mA and a maximum collector-emitter voltage rating of 40V. 2N3906 Transistor is a popular PNP bipolar junction transistor used in low power and current, medium voltage applications. 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. It is available in various through-hole packages, including the popular TO-92 package.īecause 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. The 2N3906 transistor has a maximum collector-emitter voltage rating of 40V and a maximum collector current rating of 200mA. It is a low-power transistor that is widely available and affordable. PNP SMALL SIGNAL GENERAL PURPOSE AMPLIFIER AND SWITCHĢN3906 is a PNP bipolar junction transistor (BJT) that is commonly used as a switching or amplification device in electronic circuits. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around 5V.Silicon PNP transistor in a TO-92 Plastic Package 2N3906 is a special purpose transistor that has been generally used for low current medium voltage and low power switching as well as amplification. This stage is called Saturation Region and the typical voltage allowed across the Collector-Emitter (VCE) or Base-Emitter (VBE) could be 40 and 5 V respectively. When this transistor is fully biased then it can allow a maximum of 200mA to flow across the collector and emitter. To bias a transistor we have to supply current to base pin, this current (IB) should be limited to 5mA. The maximum amount of current that could flow through the Collector pin is 200mA, hence we cannot connect loads that consume more than 200mA using this transistor. This is where a PNP transistor differs from a NPN transistor, a Logic state (blue colour) is used to toggle between Ground and Signal Voltage (Emitter-Base Voltage VBE) as shown belowĢN3906 has a gain value of 110 to 300, this value determines the amplification capacity of the transistor. The 2N3906 silicon PNP transistor is designed for amplifier and general purpose switching applications.
2N3906 is a PNP transistor hence the collector and emitter will be closed (Forward biased) when the base pin is held at ground and will be opened (Reverse biased) when a signal is provided to base pin.
