2N3906 PNP Transistor

Description

2N3906 Transistor (PNP, 40V, 200mA) The 2N3906 is a PNP transistor that is widely used in electronic circuits for small-signal amplification and switching applications. It is designed to handle moderate current and voltage levels and is commonly used in both analog and digital circuits. Key Features of 2N3906 Transistor (PNP, 40V, 200mA): Type: The 2N3906 is a PNP (positive-negative-positive) transistor. This means that current flows from the emitter (which is connected to the positive voltage) through the base and collector to the ground (negative terminal). Voltage Rating: The collector-emitter voltage (Vce) is rated at 40V, which means it can safely handle voltages up to 40V between the collector and emitter without breaking down. Current Rating: The collector current (Ic) is rated at 200mA, which means the transistor can safely carry a maximum current of 200mA through the collector. Power Dissipation: The maximum power dissipation is typically around 500mW (0.5W), meaning it can dissipate up to 500 milliwatts of power before overheating or damage occurs. Frequency Response: The 2N3906 transistor typically has a transition frequency (ft) of around 250MHz, making it suitable for applications in high-frequency switching and amplification. Package Type: The 2N3906 is available in a TO-92 package, which is a small, through-hole package commonly used in low-power and signal processing applications. Gain (hFE): The DC current gain (hFE) of the transistor typically ranges from 10
