BD202 PNP Power Transistor

Contents hide

The RCA-BD201 transistor and their complementary p-n-p type. 80202 and 80204 respectively, are epitaxial-base transistors intended for a wide variety Of medium-power switching and amplifier applications. such as series and shunt regulators, and driver and output stages Of high-fidelity amplifier.

Power Transistor?

Transistors are three-terminal semiconductor electronic devices that can be used as switches or amplifiers. They can be of NPN or PNP polarity, and many different types are available with different power and switching speed ratings. If a transistor designed to these concepts can handle more than 1 A of collector current, it is generally considered to be a power transistor. Such transistors must have low output resistance to deliver large load currents, and good junction insulation to resist high voltages.
