2N3501UB

2N3501UB is a PNP single transistor commonly used in general purpose amplifier, AF power, and non-critical switching applications. It consists of two separate PNP transistors connected together in one package, but cannot be used in digital logic circuits.

2N3501UB has a maximum collector current of 500 mA, a maximum collector-emitter voltage of 25 V and a current gain ranging from 70 to 600, depending on the collector current. The transistor is made up of two sections; one NPN and one PNP transistor, connected in the same package.

The 2N3501UB application field includes general-purpose amplification, audio amplification, and switching. It is commonly used in circuits requiring low noise, low- to medium-power linear amplification of audio and other signals, and also in power switching.

Working Principle

Bipolar transistors are three-terminal devices with two diodes and a single active component between them. They generally consist of two NPN or two PNP transistors connected in a package, with leads for the two base terminals. The remaining two terminals are the collector and emitter. When a small voltage is applied to the base, the transistor will allow a much larger current to flow from the collector to the emitter.

2N3501UB transistors are PNP transistors with the emitter, base and collector pins arranged in the order of E, B and C, respectively. The base connection is usually negative relative to the emitter, which allows the transistor to conduct current if a voltage is applied to the base. By applying a voltage to the base of the 2N3501UB, current will flow from the emitter to the collector and current will be amplified. The current gain of the transistor can be adjusted by changing the voltage applied to the base.

The 2N3501UB is a PNP transistor and has a maximum collector current of 500mA, a maximum collector-emitter voltage of 25V and a current gain ranging from 70 to 600, depending on the collector current. The collector-emitter breakdown voltage is also determined by the collector current. The collector-emitter voltage rating of 2N3501UB is 25V.

2N3501UB transistors can be used in many different applications. As one of the most popular PNP transistors, 2N3501UBs are used for general-purpose amplifier, audio amplifier, switching and other applications. They can also be used in circuits requiring low noise, low- to medium-power linear amplification of audio and other signals. In addition, they can be used in power switching applications.

In conclusion, the 2N3501UB is a popularly used single PNP transistor in general-purpose amplification, audio amplification, and switching applications. It has a maximum collector current of 500mA, a maximum collector-emitter voltage of 25V and a current gain ranging from 70 to 600. This transistor is capable of operating within safe margins and can be used in many different types of circuits.
