Introduction

The ZUMT618TC is a single bipolar junction transistor (BJT) that has a wide range of applications in electronics. It has a maximum collector-emitter voltage of 900V, with a current gain of 55. It is designed for use in high-voltage, high-current switch applications, such as voltage regulators and DC-DC converters.

Construction

The ZUMT618TC is a 3-terminal semiconductor device. It consists of an n-type base, an npn collector and an npn emitter. The base and collector are connected by a P-type layer and the emitter is connected to the base through a P-type layer.

Operation

The ZUMT618TC works using the principle of heat conduction, which is a physics phenomenon. Heat is generated in the base and then conducted through the P-type layer to the emitter and collector. This heat forces electrons to flow from the base to the emitter, creating a current. By controlling the amount of heat in the base, the current can be regulated.
