BD139 FAQ

What is BD139 transistor?

The BD139 is a NPN complementary low voltage NPN transistor in 3 pin SOT-32 package. This device is designed for audio amplifiers and drivers utilizing complementary or quasi-complementary circuits. Products are pre-selected in DC current gain. Collector to emitter voltage (Vce) is 80V. Collector current (Ic) is 1.5A.

 

Is the BD139 an NPN or PNP transistor?

These epitaxial planar transistors are mounted in the SOT-32 plastic package. They are designed for audio amplifiers and drivers utilizing complementary or quasi-complementary circuits. The NPN types are the BD135 and BD139, and the complementary PNP types are the BD136 and BD140.

 

What is BD139 used for?

BD139 is a Bipolar NPN transistor, mounted in the SOT-32 plastic package and is designed for audio amplifier and driver utilizing complementary circuits. due to its high collector current and low cost it is an ideal transistor to be used in educational electronic projects and also in commercial electronics.

 

Can I use BD139 instead of BD140?

When large currents or voltages need to be controlled, Darlington Transistors can be used. Though the best choice for power transistors is BD139 and BD140 but if they are not available then you may also go for BD135 and BD136 which are NPN and PNP transistors respectively but preference must be given to BD139/140 pair.

 

What is complementary power transistors?

Complementary power transistors are for general purpose power amplification and switching such as output or driver stages in applications such as switching regulators, converters and power amplifiers.
