MM3Z18VT1G

Diodes - Zener - Single

MM3Z18VT1G is a single Zener diode. It is categorized as a point contact single diode, and is manufactured by Zonestar Technology Co., Ltd. This type of diode is very commonly used in various electronic applications, including circuit protection, power regulation, and signal rectification for both AC and DC signals. It can be used for voltage regulation, over-voltage protection, or as a reverse polarity protection device when used in the negative supply circuit.

The MM3Z18VT1G diode features a breakdown voltage of 18V, enabling it to handle high-voltage conditions and provide reliable protection from over-voltage substations. The maximum forward voltage drop is 5.6V, with a reverse current of 8mA at 18V. In addition, the typical junction capacitance is 6pF, and the maximum thermal resistance is 0.12°C/W.

The working principle of a Zener diode is based on its ability to provide reverse leakage current when a voltage greater than the diode\'s breakdown voltage is applied. The reverse leakage current is highly sensitive to the applied reverse voltage, allowing the diode to remain in a stable state and provide a constant voltage level. When the reverse voltage is applied in excess of the breakdown voltage, the diode allows current to pass through it, and this current is referred to as the Zener current.

The typical application field of the MM3Z18VT1G is for voltage regulation and protection. It can be used for many different applications, such as stabilizing the output voltage of linear regulators and power supplies, providing reverse polarity protection, and providing over-voltage protection for sensitive electronics. It can also be used for signal rectification and to protect against overloads or accidental shorts.

To ensure the best performance and longest life of the MM3Z18VT1G Zener diode, it is important to take proper precautions when using it. It is important to ensure that the maximum ratings of the diode are not exceeded, and that proper heat dissipation measures are taken to prevent the diode from overheating. In addition, it is important to use a suitable, higher-rated power supply to ensure that the proper operation of the diode is not compromised.

The MM3Z18VT1G is an incredibly versatile and reliable Zener diode designed for both commercial and industrial applications. It can be used in a wide range of applications, including voltage regulation and protection, as well as signal rectification. It is capable of providing reliable protection from over-voltage substations and reverse polarity, while allowing current to pass through in excess of the breakdown voltage.
