3EZ27D2E3/TR8

Diodes are semiconductor components that are used to control current flow in electric circuits. They are often called rectifiers because they prevent current flow in one direction and allow it in the other direction. Zener diodes are a type of diode that is designed to allow current flow in the reverse direction while maintaining a nearly constant voltage. The 3EZ27D2E3/TR8 is a type of single Zener diode.

Application Field and Working Principle

The 3EZ27D2E3/TR8 is a single Zener diode that can be used in numerous applications from power supplies to audio equipment. It operates using a concept known as the Zener Effect, which was named after the scientist who discovered it, Dr. Zener. The Zener Effect is the result of a similar process as seen in conventional rectifiers, but instead of allowing just current to pass in one direction, it allows a small amount to flow in the reverse direction. This flow creates a nearly constant voltage threshold at the “knee” of the diode’s output voltage curve. This makes the 3EZ27D2E3/TR8 useful for applications such as voltage regulation, protection circuits, and voltage reference sources.

When the diode begins conducting, the amount of current passing through it is determined by the amount of voltage applied to the anode and cathode. This is called the forward voltage. As the voltage is increased, the current passing through the diode increases exponentially until the knee is reached, usually between 5 and 6V depending on the diode type. Beyond the knee, current passes through the diode at a near constant rate until the maximum breakdown voltage is reached and current reduces.

The 3EZ27D2E3/TR8 offers a variety of benefits for its users. Its maximum breakdown voltage is 27V, with a maximum reverse voltage of 200mV. It also provides a very low reverse leakage current of 400nA, making it ideal for applications that require a constant voltage level. Additionally, the diode is hermetically sealed in a ceramic case and has a maximum power dissipation of 350mW. This makes it extremely reliable and a great choice for safety-critical applications.

The 3EZ27D2E3/TR8 is a robust and reliable Zener diode that is used in many electronics and power applications. Its Zener Effect allows it to maintain a nearly constant voltage level above the knee of its output voltage curve, which makes it great for voltage regulation and protection circuits. Its hermetically sealed ceramic case and its low reverse leakage current provide high levels of reliability, making it a great choice for safety-critical applications.
