A 1M120ZHB0G diode is a single Zener diode. It belongs to a family of semiconductor devices, a diode specifically designed to operate in the reverse breakdown region. This type of diode has numerous application fields and can be used for both commercial and industrial purposes, as well as for hobbyists. The following article will explain the application fields and workings of a 1M120ZHB0G Zener diode.

Application Fields

The 1M120ZHB0G diode can be used in numerous applications, with its primary application being voltage regulation. It can be used in AC or DC circuits where a particular voltage needs to be regulated, such as in power rectification, power supplies, DC-DC converters, and more. This diode can also be used in high-speed switching circuits, such as transistors, diodes, and triacs. It can be used in voltage multiplier circuits and has extensive application for electronics hobbyists in radio-communications.

Working Principle

The working principle of a 1M120ZHB0G diode is based on the switching action caused by the heat generated by a reverse current. When a reverse voltage is applied across the terminals of the diode, a part of the voltage will be dropped due to the heat generated by the reverse current, maintaining a steady voltage across the diode. This way, the diode can be used to regulate the voltage in a circuit.

A voltage breakdown can be achieved if the forward current exceeds the power rating of the diode, this phenomenon is known as Zener breakdown. This occurs when the voltage is over a certain threshold, the Zener Voltage. When the voltage is below the Zener Voltage, the current flowing through the diode is very low, but when the voltage is above the Zener Voltage, the current passing through the diode increases rapidly.

The voltage regulator action of the diode is based on its ability to pass current in one direction and not in the other. When the voltage across the diode exceeds the Zener Voltage, the diode acts as a resistor, allowing current to pass from cathode to anode, resulting in the voltage dropping across the diode.

The 1M120ZHB0G diode has an operating temperature range of -55 °C to +175 °C and a reverse voltage rating of 36 to 125 volts. It has a peak power dissipation of 1200 milliwatts and a typical forward current rating of 15 milliamperes. It can be used with a variety of semiconductor devices and has a maximum junction temperature of 125°C.
