Diodes - Zener - Single

The 2EZ75D/TR8 is a single Zener diode most commonly used in electronics. It is known for its ability to maintain a constant voltage level when the input voltage changes. This makes it an ideal choice for applications where an unregulated voltage needs to be kept constant, such as power supplies.

The 2EZ75D/TR8 is a standard Zener diode composed of a semiconductor material with a PN junction. It is designed to operate at a reverse voltage level, meaning that the voltage is applied in reverse to the direction of normal current flow. It is capable of regulating the output voltage over a wide range, making it useful for voltage regulation in low voltage applications.

The 2EZ75D/TR8 has a breakdown voltage of 7.5 Volts, with a nominal zener voltage of 5.5V, meaning that it can maintain a voltage output of 5.5V when the input voltage exceeds 7.5V. This can be useful in applications where the input voltage is expected to fluctuate significantly. It has a maximum power rating of 500 mW and a zener current of 56 mA.

The working principle of the 2EZ75D/TR8 is relatively simple. When the input voltage exceeds the Zener voltage, it will begin conducting current in the reverse direction, thus limiting the output voltage to the Zener level. The amount of current conducted is determined by the quiescent current, which is the current drawn when no voltage is applied. This current is small and typically does not affect the operation of the device.

The 2EZ75D/TR8 is commonly used in power supplies and other DC/DC converter applications. It can also be used as a voltage reference to maintain a fixed output voltage level, or as a protection diode to protect other components from overvoltage damage. It can also be used in overvoltage protection circuits, or to limit current or voltage in switching applications.

The 2EZ75D/TR8 is available in a range of packages, including the SOD523, SOT23, SOT89 and TO-220. It is also available in through-hole, surface mount and surface mount reflowable packages. It is relatively inexpensive and robust, making it a popular choice for many applications.

In conclusion, the 2EZ75D/TR8 is a single Zener diode that is commonly used in electronics applications to maintain a constant voltage level and to act as a protection or limiting device. It has a nominal breakdown voltage of 7.5V and a zener voltage of 5.5V, and has a range of useful features and applications.
