2STW1693

Introduction

2STW1693 is a NPN Transistor, suitable for many power amplifying and switching applications. It is a BJT (Bipolar Junction Transistor) with a single emitter. It was mainly used in the military and aerospace systems due to its high reliability and extremely rugged construction.

Application Field

2STW1693 is used in a wide range of applications including linear and switching power amplifiers, radio transmitters, and automotive driver and control circuits. It is also suitable for various switching applications and switching amplifiers. Its relatively low current gain allows it to be used as a low level amplifier in circuits which require only a small amount of current gain. This makes it an ideal choice for applications where high efficiency and low power consumption are needed.

Working Principle

2STW1693 is an NPN transistor, meaning it consists of one emitter and one collector. In this case, the emitter is made up of a P-type semiconductor and the collector is made up of an N-type semiconductor. When a current is applied between the two nodes, electrons flow from the emitter to the collector, allowing current to flow from the collector to the emitter. As the current from the collector increases, the voltage drop between the collector and the emitter increases, allowing for greater current to flow through the transistor.

The current gain of a transistor is a measure of the amount of current that can be produced for a given amount of base current flowing through the transistor. In this case, the current gain of 2STW1693 is relatively low, as it is designed to provide low power, low current gain. As current from the base increases, the current gain of the transistor increases and the voltage drop across the transistor decreases.

Conclusion

2STW1693 is a single emitter NPN transistor with low current gain, making it ideal for applications which require low power and low current gain. It is most commonly used in radio transmitters, amplifiers, and various switching applications. Its rugged construction has made it popular in military and aerospace systems.
