2EZ82DE3/TR8 Diodes - Zener - Single Application Field and Working Principle

A zener diode, like the 2EZ82DE3/TR8, is a type of diode specifically designed to operate in reverse bias. A zener diode\'s characteristics allow it to remain in either its nonconductive or conductive states. It can be used to protect other circuits by providing a pathway for current away from the device it is protecting or to provide a reference voltage for different circuits.The 2EZ82DE3/TR8 Zener diode is a single PN junction diode designed to operate at its breakdown voltage of 8.2V. The breakdown voltage is the voltage at which the current flowing across the junction increases exponentially as the voltage increases. Above this breakdown voltage, the characteristic changes abruptly, and current is able to pass through the junction without any additional voltage applied across it.The 2EZ82DE3/TR8 is available in an SOT-23 package, which is a small surface mounted package able to be mounted on small PCBs with a minimum of space required. To function, the 2EZ82DE3/TR8 requires a minimal forward current to turn on and a minimum reverse bias voltage to enter it\'s breakdown voltage. When the 2EZ82DE3/TR8 is in its breakdown voltage range it is essentially indestructible due to its clamping action. The clamping action of a zener diode is when the device clamps the voltage at the diode’s breakdown voltage. This allows for voltage regulation, voltage protection, and voltage reference. It can also function as an overvoltage protection device due to its ability to limit the maximum voltage on a given circuit. This is done by connecting the diode with its anode connected to the voltage source and its cathode attached to the desired maximum voltage. By doing this, the zener diode will clamp the applied voltage to the desired voltage in the event of an overvoltage and thereby protecting the circuit.The 2EZ82DE3/TR8 Zener diode can also be used as a voltage reference device due to its precise breakdown voltage. By connecting the circuit in reverse bias and connecting a reference voltage to the anode, the V-I characteristic of the 2EZ82DE3/TR8 will provide a voltage drop that can be used as a reference voltage for a different circuit.In summary, the 2EZ82DE3/TR8 Zener diode can be used for a number of applications for example, overvoltage protection and voltage reference. It is a small surface mounted device with a breakdown voltage of 8.2V and a clamping action that is designed to regulate voltage and protect circuits from overvoltage.
