3EZ180D/TR12 is a diode that is used for Zener voltage regulation and power supply applications in a wide variety of electronic items such as computers, DC-DC converters, and audio equipment. It is a single Zener diode that is used for voltage reduction in a number of applications. It works by connecting at least two electrical paths in a circuit that have different electrical potentials.

The Working Principle

3EZ180D/TR12 works by using a property of a diode known as “reverse bias voltage.” In other words, the diode passes with a certain voltage when the electrical charge is of a certain polarity. It then blocks current when the electrical charge is at the opposite polarity. This is how the diode reduces voltage, with the voltage reduction being determined by the diode’s reverse bias voltage.

The basic structure of the 3EZ180D/TR12 consists of two p and n type semiconductor terminals joined together to form a rectifying junction. When a voltage is applied across the terminals in one direction, electrons will flow from the n type to the p type terminal, as the n type is negatively charged and the p type is positively charged. This creates an electron flow from negative to positive, called forward bias. If the same voltage is applied in the opposite direction, it will be blocked by the diode, resulting in no electron flow. This is called reverse bias, and the voltage at which this occurs is the diode’s Zener voltage.

The Zener voltage of the 3EZ180D/TR12 is between 5.2 and 6 volts, depending on the operating temperature and the device’s temperature coefficient, which is determined by the Zener current. When the Zener voltage is reached, the diode will begin to conduct and the voltage across the diode will reduce accordingly. This allows the voltage in the circuit to be regulated, as the diode will always conduct at a voltage equal to or less than the applied voltage.

Application Fields

The 3EZ180D/TR12 is typically used for voltage regulation and power supply applications such as DC-DC converters, computers, and audio equipment. Its high Zener rating makes it suited for applications that require a precise level of voltage control. It can also be used to clamp transients and to reduce ripple, EMI, and RFI noise. The diode’s precise Zener voltage and low temperature coefficient allow it to provide excellent regulation over a wide range of temperatures.

The 3EZ180D/TR12 has some interesting features as well, such as its non-saturated reverse conduction capability. This allows the diode to dissipate considerable energy without being damaged. The diode also features a low Zener impedance, which minimizes power dissipation, making it very efficient. It is an ideal choice for applications which require precise voltage control at high current and power levels.
