DDZ7V5C-7 Discrete Semiconductor Products

DDZ7V5C-7 is a single Zener diode. It is primarily used in voltage regulating circuits, exchanging current while maintaining a constant voltage level. It is typically applied in LED drivers, LCD displays, and other consumer electronics.

A Zener diode consists of two regions, a P-type and an N-type. When a Zener diode is forward-biased, it works in the same way as a normal diode and only allows current to travel in one direction, blocking it from the reverse direction. When the voltage across the diode is higher than its reverse breakdown voltage (V_Z) the diode “breaks down” and allows current to flow in both directions. The main difference between a normal diode and a Zener diode is that the voltage across the Zener diode is stable and remains constant, even if the voltage source changes. This property of Zener diodes makes them useful in regulating applications in which a constant voltage is required.

In the case of the DDZ7V5C-7, the reverse breakdown voltage is 7V, meaning that the voltage across the diode will remain at 7V as long as the diode is not overloaded. When 40 mA is used as an example, the maximum forward voltage is 4V. This means that the diode allows currents to freely flow in the forward direction until 4V is reached and any further increase in current would cause an increase in voltage, leading to an overload. It is for this reason that Zener diodes are not used with high current flows.

The DDZ7V5C-7 is designed to be used in applications which require constant voltage regulation in spite of varying current flows. Due to its low power dissipation and chip form, it can be directly mounted onto the circuit board, making it ideal for applications in LED lighting and LCD displays. Additionally, it is extremely reliable, with a maximum current rating of 1.5A and an operational temperature range of -55°C to +125°C.

In conclusion, the DDZ7V5C-7 is a single Zener diode that is primarily used in applications which require constant voltage regulation in spite of varying current flows. It is most suitable for applications in LED lighting and LCD displays due to its low power dissipation and ability to be directly mounted onto the circuit board. Additionally, it is extremely reliable, with a maximum current rating of 1.5A and an operational temperature range of -55°C to +125°C.
