1EZ190D5/TR8

Diodes - Zener - SingleDiodes Zener Single is a type of diode that operates in reverse bias. The diode allows electric current to flow in reverse direction in order to maintain a specific voltage drop across the diode junction.The 1EZ190D5/TR8 is a type of silicon zener diode with a nominal zener voltage of 5.6V, a maximum forward voltage of 1.35V at 300mA and a maximum reverse current of 0.1mA. This type of diode is specifically designed for use in circuit applications that require a constant voltage, such as voltage regulators, voltage references, and voltage limiters.The working principle of a Zener diode is based on the principle of Zener breakdown, which is a process in which the electric field across a reverse-biased P-N junction exceeds the dielectric strength of the depletion region, thus allowing a very small electric current to flow through the diode. The Zener diode has a reverse breakdown voltage that is usually set by the manufacturer, but the voltage can be adjusted by adjusting the doping of the diode.The Zener diode is typically used in DC voltage regulation applications, as it can be used to maintain a constant voltage by connecting it in parallel with the power supply. This is because if the voltage on the load increases, more current will flow through the Zener diode, resulting in more voltage drop across the diode, thus reducing the voltage at the load. Similarly, if the voltage on the load decreases, less current will flow through the Zener diode, resulting in less voltage drop across the diode, thus increasing the voltage at the load.The Zener diode can also be used as a voltage reference or voltage limiter, as it can be used to either limit the voltage on the load, or set it to a certain reference voltage. The Zener diode can also be used as a current regulator by connecting it to a variable-voltage power supply, as it will limit the current through the diode by adjusting the voltage on the power supply, resulting in a change in the voltage drop across the diode.The 1EZ190D5/TR8 can also be used in voltage protection circuits, as it can be used to limit the voltage across an electronic circuit in the event of a power surge or fault. This application is more commonly seen in portable electronic devices, as these devices often contain sensitive components that can be damaged by excessive voltage.The 1EZ190D5/TR8 can also be used in other applications such as temperature compensation, temporary DC power supply, and standby power supply.In conclusion, the 1EZ190D5/TR8 is a type of silicon zener diode which is primarily used in circuit applications that require a constant voltage. It is typically used for DC voltage regulation, voltage reference, voltage limitation, and voltage protection. It is also used in applications such as temperature compensation, temporary DC power supply, and standby power supply.
