MTZJT-7718C is a single Zener diode with medium power capacity, which is one type of PN-junction diode. It is a semiconductor device with a wide range of uses, such as creating a voltage reference, providing voltage clamping and rectification. Below we will discuss its application fields, working principle and other properties.

Application fields

Due to its wide range of features and options, the MTZJT-7718C is used in numerous applications, including:

• Voltage reference: MTZJT-7718C can be used as the reference for a voltage regulator, for example, in a telephone circuit, audio amplifier and DC-DC converter.
• Voltage clamping: In this application, the Zener diode will not conduct until the input voltage exceeds a specific value. When the voltage reaches that level, the diode begins to conduct and then limits the current.
• Rectification: This is a common application in many electronics devices, where the Zener diode can be used to rectify AC power to DC power.

Working principle

The working principle of MTZJT-7718C is similar to that of a PN-junction diode, which is also known as a Zener diode. In a PN-junction diode, two types of doped materials are combined to form a junction. The doped materials are known as N-type and P-type semiconductors, with each containing excess carriers of negative and positive charge, respectively. When a voltage is applied across the diode, the electric field that is created causes the electrons in the N-type region to move towards the P-type region and the holes in the P-type region to move towards the N-type region. This process causes the two regions to become more neutralised as the electrons and holes move in opposite directions.

When the voltage across the diode reaches a certain level, known as the Zener voltage, the current can flow in both directions through the diode. This is a phenomenon known as Zener breakdown, so this type of diode sometimes referred to as a Zener diode.

Other Properties

In addition to its versatility in different applications, the MTZJT-7718C also has other properties that make it especially useful. For example, it has a data retention voltage range of 5.8V-7.2V, making it suitable for use in a range of applications.
