MTZJT-726.8C Application Field and Working Principle

As an increasingly important component of electronic products, Single Zener Diodes, specifically our focus MTZJT-726.8C, are used in all kinds of fields. They are widely used as tight-tolerance voltage references, over-voltage protection, and low-frequency high-voltage rectification. Meanwhile, this diode has plenty of applications in the telecommunications and control areas, such as AC voltage regulator and voltage stabilizer. This diode also has many other uses, such as DC voltage regulator, small integrated power supply, semiconductor detector, etc.

The MTZJT-726.8C (Single Zener Diode) was invented by Hazama Hisatsuchi and Junichi Hosomi in 1949 at the Japanese corporation Nippon Gakki, also famously known as Yamaha. To understand the working mechanism that makes Single Zener Diode great, let’s consider the semiconductor junction first. The junction is a PN junction, a place where the semiconductor is doped with “P”-type material on one side and “N”-type material on the other side, forming a contact between the two. This junction is placed in low resistance, allowing for the flow of electrons.

The working principle of the MTZJT-726.8C (Single Zener Diode) lies in the “Zener breakdown” effect. This is the phenomenon which occurs inside a diode when a reverse voltage is applied across it surpasses the prescribed ‘breakdown voltage’. The diode then begins to conduct current in the reverse direction and ensures a constant voltage across itself—this is known as the ‘Zener voltage’. The current that is let through the device can be calculated by the following equation:

Where the applied voltage Vz is equal to the Zener voltage, and Rz is the ‘internal resistance’ of the diode. We can see from here that the slightly higher applied voltage across the PN junction does not overcitatively lead to damaging current spikes.

The MTZJT-726.8C (Single Zener Diode) can be checked in many ways, including testing with a simple ohmmeter or multimeter. It has multiple tolerances according to its specific applications, though it usually operates with a 5% tolerance. The MTZJT-726.8C also comes with a built-in breakdown voltage range of 5–12V, which helps make it suitable for a wide variety of uses.
