筆記：

Table MJE2955 is the most suitable replacement, his voltage and power which are appropriate, the package type is also the same. 2N2222 and BD139 replacement should pay attention to see the current parameters, respectively, can not be more than 800mA and 600mA. use S8050 and C945 replacement is not only look at the parameters of the time, because he packages are not the same, you need to look at the specific in the application can be mounted. application can be installed.

TIP31C Circuit

emitter ground or power supply negative

TIP31C is a typical NPN transistor, his three poles wiring are: base control transistor conduction, collector on the load and positive,emitter ground or power supply negative his maximum load voltage of 100V, but the collector current is about 3A. usually used in low-power amplification, as a switch, regulator and so on.

He can be used in conjunction with other triodes to drive motors. The potentiometer regulates the voltage input to the base of the BFY51, the BFY51 amplifies this signal to control the conduction of the TIP31C, and the TIP31C amplifies the current to drive the motor.There are many other models of the TIP31C that can be replaced, such as: TIP122 , TIP121, TIP120, 2N6288, 2N6290, 2N6292.
