The 2N3905 is has not exactly the same specs as the 2N3906 but can be used as a replacement in most of the conditions. The emitter to base voltage of the transistor is 5.0V, total device dissipation is 625mW, max DC current gain is 150, maximum transition frequency is 200MHz and NF or noise figure of transistor is 5.0dB.Īs you already know that 2N3906 is a famous general purpose transistor and you can find it in many commercial appliances, equipment and also in many educational projects. The maximum collector current of the transistor is 200mA which means it can handle load of upto 200mA and the maximum load voltage can be upto 40V.
The transistor is built to perform general purpose tasks of switching and amplification in electronic applications. The pin configurations of these transistors may differ from the 2N3905, so it is recommended that you check the pinout of the transistor you are replacing before soldering into the circuit or using it in your circuit design.ĢN3905 Transistor Explained / Description:ĢN3905 is a small signal general purpose BJT transistor available in TO-92 package.
Minimum & Maximum DC Current Gain (hFE): 15 to 150.Max Collector-Emitter Voltage (VCE): 40V.
