The wiring diagram of the BD135 transistor shows three basic components: base, collector and emitter.<br \/>Connecting the BD135 begins with identifying these three legs.<br \/>It is important to remember that improper connection can lead to device failure or even damage to the transistor.<\/p><p>The basic components of the BD135 connection are:<\/p><ul style=\"font-size: 16px; background-color: #ffffff;\"><li style=\"font-size: 16px;\"><span style=\"font-weight: bolder;\">Base<\/span> &#8211; is connected to the control voltage of the transistor.<br \/>This voltage determines whether the transistor is in the conducting state or not;<\/li><li style=\"font-size: 16px;\"><span style=\"font-weight: bolder;\">collector<\/span> &#8211; the place where the current from the transistor is &#8220;collected&#8221;, it is usually connected to the power supply;<\/li><li style=\"font-size: 16px;\"><span style=\"font-weight: bolder;\">Emitter<\/span> &#8211; is used to

different models may have slightly different connection rules.<br \/>Remember also that it is the control voltage at the base that determines the state of the transistor &#8211; whether it is &#8220;open&#8221; (passes current) or &#8220;closed&#8221; (does not pass current).<br \/>Given the above information, connecting the BD135 becomes an understandable and achievable task for any
