What is the 8050 transistor?
8050 transistor is a negative positive negative (NPN) epitaxial silicon transistor, which is used as a push-pull class B in portable radio applications. This transistor is usually used along with the compliment of PNP, 8550, in the Push-Pull amplifier amplifier. The 8050 transistor evaluation and 8550 transistor are identical. The difference is in their polarity.
The basic transistor is a semiconductor device, which is created by placing a layer of semiconductor material between two layers of material with the opposite polarity. The NPN transistor has a layer of positive material lying between two layers of negative material. Positive negative-positive (PNP) transistor has a negative layer between two positive layers is known as PNP transistor.
Each of the layers in the transistor has a line. The resulting terminals are known as the emitter, base and collector. The base is always a middle layer.
The transistor is essentially an electronic switch. VoltageECE and load is connected via the collector and emitter terminals. The transistor is off without voltage voltage at the base terminal. When the voltage of the correct amplitude and polarity is applied at the basic terminal, the transistor turns on, allowing a flow of much larger current between the emitter and the collector.
The voltage that is needed to control the status of the on-off transistor is small. The transistor can therefore be used as an amplifier. The base of the-emiter controls the current flowing through the circuit of the emitter.
The silicone transistor usually turns on when the basic voltage is 0.65 volts higher than the emitter. The emitter base is usually set to provide a preset voltage that is close to the starting point. This is known as bias. While the transistor performs, the output follows of the input formula.
transistors can be set to amplify the entire input course if it isVoltage of the whole wave shape above the transistor trigger. This means that the transistor will perform even if no input is applied. This creates a very noisy output. In order to avoid excessive noise and more efficient circuit, push-pull amplifiers have been created.
Push-Pull amplifier uses two transistors of opposite polarities. When the form of input wool is in the positive half of the cycle, the transistor NPN will perform and the transistor PNP will turn off. If the input signal turns negative, the PNP transistor will be carried out and the NPN transistor turns off. Both outputs are combined to create a complete reinforced signal.
8050 transistor and its equivalent 8550 have been designed to be used as an additional pair of transistors in low power applications. Specification sheet for transistor 8050 and 8550 transistor can be found by searching on the web for part number. In general, the transistor 8050 2-watt amplifier with maximum collector emitter current 1.5 ampera and maximum EMIT voltageURU collector 25 volts.
