DSM80101M-7

Introduction

The DSM80101M-7 is a simple and low cost Bipolar Junction Transistor (BJT) that is used in many applications. A BJT is a three terminal device typically composed of two PN-junction diodes that are held together in a single body by a semiconductor. These devices are mainly used for various applications such as power switching, amplification, and in linear circuits.

Application Field

The DSM80101M-7 is ideal for many applications in the electronics field. This BJT can be used in power switching applications to turn devices on and off using a low power signal. It can also be used in amplifier circuits to provide voltage gain, current gain, and input/output impedance matching. This device can also be used in linear circuits to allow for precise control of the circuit’s output. Additionally, BJTs can be used as transistors in oscillator circuits that emit a particular frequency based on the bias of the BJT.

Working Principle

BJT’s behave differently in response to a varying base current which is connected to the base terminal of the transistor. A BJT receives input signals through the base terminal and amplifies those signals in response to the varying base current. A low current into the base terminal will produce a larger current in the collector and emitter. A high current into the base terminal will produce a small or no current in the collector and emitter. This principle is used in power switching as well as amplifier applications.

A BJT also operates differently in response to a varying collector current which is received from the collector terminal of the transistor. A low current into the collector terminal will cause the BJT to operate in an active region, meaning that the base current will increase in order to keep the collector-emitter current constant. On the other hand a high current into the collector terminal will force the BJT to operate in a saturation region, meaning that the collector-emitter voltage will be almost equal to the base-emitter voltage.

Conclusion

The DSM80101M-7 is a simple and low cost Bipolar Junction Transistor (BJT) that is used for many applications, such as power switching, amplification, and in linear circuits. A BJT responds differently in response to a varying base or collector current in order to switch power or amplify signals, depending on the application. This device works well in many areas and is a valuable tool in the electronics field.
