The BD139 is a widely-used NPN (Negative-Positive-Negative) bipolar junction transistor (BJT) known for its versatility and reliability in various electronic circuits.
Maximum Collector-Base Voltage (Vcb): Typically around 80 volts.
Maximum Collector-Emitter Voltage (Vce): Usually around 80 volts.
Maximum Emitter-Base Voltage (Veb): Generally around 5 volts.
Collector Current (Ic): Typically up to a few amperes (commonly around 1.5A).
Power Dissipation (Pd): It can handle power dissipation up to several watts (commonly around 12.5W).
Gain (hFE or β): Typically falls in the range of 40 to 250, depending on operating conditions.
Package Type: The BD139 transistor is commonly available in a TO-126 or TO-220 package, which provides good thermal dissipation.
