2EZ7.5D/TR8

The 2EZ7.5D/TR8 diodes are a type of Zener single diodes. It is a low voltage and low power version. These diodes are used in linear voltage regulation, waveform clamping, and surge suppression applications. They are also used in AC line suppression and in DC power supplies.

The 2EZ7.5D/TR8 has a maximum reverse voltage of 7.5V and a maximum power dissipation of 300mW. This diode is available in a variety of package styles such as DO-35 (standard), TO-92 (miniature), and SOT-223 (surface mount).

The working principle of the 2EZ7.5D/TR8 improves upon that of traditional Zener diodes by using two distinct junction layers. These layers are optimized for both high current application and high-speed operation. The first junction layer has a much lower resistivity and acts as the main current path when active. The second junction layer is much slower and acts as the Zener layer when the active junction is forward biased.

In operation, the 2EZ7.5D/TR8 conducts current in the reverse direction when its reverse voltage exceeds the Zener voltage. This voltage is determined by the Zener-impedance characteristics of the two junction layers. As the voltage across the diode exceeds the Zener voltage, the breakdown current narrows and increases sharply. This reduces the power dissipation of the diode.

Due to the low voltage and low power dissipation, the 2EZ7.5D/TR8 is ideal for a wide range of applications, from power management systems to AC line suppression and pulse clamps. The low Zener impedance of the two junction layers allows for quick response time, making it perfect for DC power supplies and high frequency applications. Furthermore, its tight tolerance makes it excellent for precise voltage regulation.

In summary, the 2EZ7.5D/TR8 diode is a low voltage, low power Zener single diode. It features two distinct junction layers, which make it suitable for a variety of applications, from AC line suppression and linearly voltage regulation to surge suppression and high frequency applications. With its low Zener impedance and tight tolerance, the 2EZ7.5D/TR8 is a versatile diode for all types of voltage regulation, waveform clamps, and power management systems.
