The 2N3906 is a commonly used PNP (Positive-negative-Positive) bipolar junction transistor used for general-purpose low-power amplifying and switching applications. It is designed for low electric current and power and medium voltage, and its operating speed is very high. It comes in a plastic TO-92 compact casing. 2N3906 Pinout description, features, and equivalent are given below in detail.
The circuit symbol of 2N306 is shown in the figure below.
Alternate of 2N3906 isZTX555, BC557, BC558, 2N4403, MPSA13, MPSA92, MPSA55 etc.
NPN Complementary of 2N3906 is 2N3904
The 2N3906 is a widely used PNP(Positive-Negative-Positive) transistor. It is very similar to the bc557 transistor only difference is that it has a high collector-to-emitter voltage. It is not suitable for amplifier circuits because of the gain value of only 300.
The 2N3906 transistor might be the right choice for you if you are looking for a PNP transistor that could switch high voltage loads within 0.2A
For the good performance of the transistor, it is suggested to not operate a load of more than 200mA. 2N3906 Pinout must be checked before use. Always use a suitable base resistor and confirm the pin configuration before placing the circuit to place it right, must keep the temperature range between -55 centigrade and above +150 centigrade.
The 2N3906 is the most commonly used PNP transistor. It is almost similar to the bc557. the only difference is that it has a high collector-to-emitter voltage. This transistor is not suitable for amplifier circuits because it has only a gain value of 300.
