2EZ20D/TR12 Application Field and Working Principle

The 2EZ20D/TR12 is a type of Zener (avalanche) diode which is a semiconductor device typically used to regulate voltage across a circuit. This particular type of diode is categorized as a single-zener diode and is designed to withstand reverse voltage and provide a stable voltage output without the use of any external components. As it is a single-zener diode, the voltage output is produced between the anode and cathode of the diode and not across the external circuit.

Applications

The main applications of the 2EZ20D/TR12 are in the electronics industry, in the form of:

• Voltage reference
• Automotive regulator
• Voltage stabilization
• Voltage clamping
• Signal code changers
• Inverters

The 2EZ20D/TR12 Zener diode is also widely used in computer systems and telecommunications equipment.

Working Principle

The main function of a Zener diode is to provide a stable voltage output. It works by using the characteristics of a PN junction diode combined with a Zener voltage regulator. The PN junction is made from two pieces of doped semiconductor material, a P-type semiconductor material and an N-type semiconductor. When the diode is forward-biased, the PN junction is forward-biased and a current occurs which is proportional to the voltage applied. When this voltage exceeds a certain point, the Zener junction begins to break down and a second current is created. This second current is referred to as the Zener current and is the same irrespective of the applied voltage.

When a reverse voltage is applied to the diode, a depletion region is formed at the PN layer, preventing current from flowing. The reverse breakdown voltage will not be exceeded even at higher voltages, allowing a stable voltage signal to be used in a wide range of applications. The Zener diode therefore works by regulating the voltage across its terminals to a predetermined value, producing a regulated output signal which is the same regardless of the input voltage.
