PXT2907A,115 Discrete Semiconductor Products

Introduction

The PXT2907A,115 is a single bipolar junction transistor (BJT). This type of transistor is a three-terminal semi-conductor device that is used as an electronic switch or amplifier in various circuits. The PXT2907A,115 transistor is developed as a general purpose transistor and it is used in audio power amplifiers, lighting and heating elements, motor controls and telecommunications applications.

Working Principle of the PXT2907A,115

Bipolar junction transistors are made of two p-type and one n-type silicon semi-conductor material connected together. This combination of semi-conductor materials makes the current flow from the collector through the base and out to the emitter. The transistor acts like a normally-closed switch; when a voltage is applied to the base of the transistor it switches on, allowing current to flow through the device. When the voltage is removed, the switch is turned off and the current stops flowing.

The current gain of a bipolar transistor is referred to as the collector current divided by the base current, this is known as hFE. The hFE of the PXT2907A,115 is typically 200 at 25oC, meaning that for every 1mA of base current it will be able to switch 200mA of collector current.

Application Field of the PXT2907A,115

The PXT2907A,115 is a general purpose transistor and can be used in a wide range of applications. This type of transistor is suited for use in audio power amplifiers, lighting and heating elements, motor controls and telecommunications applications.
