Diodes - Zener - Single

The 1EZ130D5/TR8 is a single zener diode. It is very suitable for applications where an ideal diode is needed for protection and switching, such as in the power supply industry. Zener diodes are a type of special silicon semiconductor that exhibits a reverse voltage breakdown which makes them useful for voltage regulation and voltage clamping.

Application Field and Working Principle

The 1EZ130D5/TR8 zener diode has versatile applications in the power supply industry. It is often used as a protection device, blocking excessive currents in the circuit, such as when the power supply voltage is overloaded. When a voltage is present on the device’s anode, it will cause the junction to breakdown, redirecting the excessive current away from the circuit and protecting it.

In addition to protection, zener diodes are also commonly used as voltage references, stabilizers, and voltage dividers. A zener diode acts as a voltage reference when connected in reverse-bias mode and provides a stable reference voltage output. When used as a voltage stabilizer, the zener diode acts as a shunt regulator, reducing output voltage fluctuations regardless of the load resistance. Zener diodes can also be arranged together in series for various voltage division applications.

1EZ130D5/TR8 has a maximum forward voltage drop of 0.77V at 5A current, a low capacitance of 7pF, and a reverse breakdown voltage of 13V at a 5mA current. It has a power dissipation rating of 550mW and a maximum operating temperature of 175°C. Its fast switching speeds are ideal for high-frequency applications, making it suitable for a wide range of applications.

In summary, the 1EZ130D5/TR8 is a specialized zener diode ideal for high-frequency power supply applications. It is able to protect circuits from overloads, provide stable reference voltages, and act as a voltage divider. Its fast switching speeds, low forward voltage drop, and high power dissipation rating make it a versatile choice for many different types of applications.
