2EZ91D/TR8 Application Field and Working Principle

The 2EZ91D/TR8 is a single Zener diode. It is primarily used for voltage regulation in a wide range of applications, including power supply circuits, automotive electronics, motor controllers and telecommunications systems.

Zener diodes are a type of diode that allow small amounts of current flow in one direction while maintaining a constant reverse-bias voltage, or breakdown voltage. The small current (leakage current) flowing through the diode is proportional to the breakdown voltage. This type of diode is designed to have a breakdown voltage of approximately 4 to 54 volts.

The most common use for a Zener diode is as a voltage regulator. It is connected in such a way that it acts as a shunt to regulate the current in the circuit. When the current in the circuit rises above the breakdown voltage, the diode begins to leak current. This reduces the voltage across the rest of the circuit and keeps it from rising any higher. This same principle can be used to regulate a negative voltage in the same manner.

The 2EZ91D/TR8 can also be used in other applications such as protection circuits, voltage reference circuits and signal switching circuits. By adding a resistor to the circuit, the Zener diode can also be used as a current limiter.

The 2EZ91D/TR8 is designed to have a low operating current, typically less than 100 µA. It also has a low reverse breakdown voltage and is rated for a maximum power dissipation of 500 mW. It is also designed to have an operating temperature range of - 40°C to + 85°C.

Overall, the 2EZ91D/TR8 is a versatile Zener diode that can be used in a variety of applications. It is especially suited for voltage regulation and protection applications due to its low operating current and low breakdown voltage. Additionally, its wide operating temperature range makes it suitable for a variety of environments.
