Diodes - Zener - Single: 3EZ120DE3/TR12 application field and working principle

The 3EZ120DE3/TR12 zener diode is a single component that can be used for various applications. It is a three-terminal, reverse-conducting, avalanche-rated device with a zener voltage tolerance of ±5% over temperature. The diode has a high-temperature operating range from -55°C to 125°C, making it suitable for use in a variety of applications.

The 3EZ120DE3/TR12 is designed to provide a stable voltage reference in applications where noise and temperature changes are a concern, such as in power supply circuits, telecommunication systems, and electronic instrumentation. It is also used in applications that require constant reference voltage, such as in current limiting and surge protection.

The 3EZ120DE3/TR12 works by having a reverse voltage applied to it that is above the zener voltage. This causes the diode to avalanche, allowing a controlled current to flow through the diode. This current output is then used as a voltage reference for the circuit.

The 3EZ120DE3/TR12 can also be used as a series regulator in high-current circuits by using a current-limiting resistor in series with the diode. This allows the diode to regulate the voltage across the series resistor and limit the current through it, providing a stable power source for the circuit.

The 3EZ120DE3/TR12 is an ideal choice for any application that requires stable voltage regulation. It is reliable, easy to use, and has a wide temperature range of operation. With its high thermal and electrical capability, the 3EZ120DE3/TR12 is sure to meet the requirements of any application.
