Transistors are active components in the breath of the electrical engineering history, since their introduction in the second world war. PBHV9215Z,115 is an NPN type bipolar single transistor kind among them for which we will discuss its applicability and working principle in this article.

Basics of a Transistor

Transistors have three terminals connected to a semiconductor material. The most basic transistor is the bipolar junction transistor or BJT. It works by using electrons, given by the base terminal (control) to amplify a current provided between the emitter and collector terminals (input and output).

In the case of bipolar transistors, the majority carrier is the electrons. A small amount of current at the base terminal is amplified by millions of times, providing a substantial current between the emitter and collector terminals. It amplifies electricity much like an amplifier boosts sound.

PBHV9215Z,115 Application Field

PBHV9215Z,115 is a NPN type bipolar single transistor. These types of transistors can be used as switches; therefore, it can work as a switch in any electronic circuit. With an electricity current, it can act as an open and close switch.

Moreover, PBHV9215Z,115 transistors are also used for signal amplification and voltage multiplying. This kind of transistors are often used in radio transmission systems and radio receiving systems, mainly in receiver amplifiers, audio amplifiers, and oscillators. In addition, it is used in DC to DC converters, voltage regulators, power switching circuits, general purpose interface circuitry, and signal switching circuits.

Working Principle of PBHV9215Z,115

PBHV9215Z,115 is an NPN type bipolar single transistor working under a collector-emitter voltage of 60V and a collector current of 15A. Additionally, it has small signal current gain of 2000. This type of transistor has two P-type and one N-type sections.

To start functioning, it requires a base current as an input signal that is allowed to flow from the emitter to the collector. This input signal carries an electric charge that is supplied to the base current. When the base current reaches the transistor, it forms an electrical field between the N-type and the P-type regions, this causes the electrons from the N-type region to be pushed toward the P-type region.

The electrons will flow across the already existing electric field in the base to collector and emit a larger current as output. This current can be amplified millions of times, depending on the gain ratio of the transistor. That amplified current will be the same as the input current, but with an addition of some voltage across it. The output current can be used to drive any loads like LED\'s, relays and other electronics gizmos.

Conclusion

PBHV9215Z,115 is a NPN type transistor that can be used as an amplifier, voltage multiplier, and switch. It has an input voltage of 60V and collector current of 15A and provides an amplified current of up to 15A as output. It requires a base current to start functioning and amplifies the current across it.
