DDZ7V5BQ-7

Diodes - Zener - Single

The DDZ7V5BQ-7 is a single chip Zener diode, which is used in applications that require an adjustable current and voltage limit. This diode is available in a small 3-pin TO-92 package and operates over a wide temperature range from -55°C to +150°C. It is a low-power, low-leakage, high-efficiency solution for applications such as voltage regulation, power management, and transient protection.

Application Field & Working Principle

The DDZ7V5BQ-7 Zener diode is used primarily in voltage regulation and transient protection circuits. It is most commonly used in low-power applications such as laptop power supplies and other low-power electronic equipment. The diode works by allowing current flow in one direction, and by occasionally allowing reverse current flow when the forward voltage exceeds a certain threshold (known as the Zener voltage).

The device is designed to allow minimal current flow in either direction, but when the forward voltage exceeds the Zener voltage, the diode becomes reverse-biased and the current is diverted to a different path. This helps to limit the junction voltage to the Zener voltage. This also helps in providing transient protection by diverting the excess current away from the circuit.

In addition to voltage regulation and transient protection, DDZ7V5BQ-7 diodes are also used in power supply circuits to provide over-voltage protection and surge protection. By allowing the current to flow in the reverse direction, these diodes can help protect sensitive components from high voltages.

The DDZ7V5BQ-7 Zener diode is an efficient and reliable solution for voltage regulation and transient protection needs. It has a very low power dissipation, high temperature stability and exceptionally fast switching speeds, making it an ideal choice for modern power management systems. With its small size and high efficiency, it is a great choice for low-power applications.
