1N5544BUR-1

1N5544BUR-1 is a single-phase, medium power diode with an integrated Zener, specifically designed for precision regulation and voltage clamping. It is designed to provide the highest degree of elasticity and accuracy in applications. The device has a total breakdown voltage of 9V, a maximum reverse voltage of 1.5V, a maximum power dissipation of 500mW, and a maximum reverse leakage current of 8 μA.

Application Field

1N5544BUR-1 is commonly used in precision voltage regulation and voltage clamping applications. It may be used as a linear or nonlinear voltage regulator, as a voltage driver, as a precisely determined voltage clamping device, or any other application which requires a regulated, clamped voltage. 1N5544BUR-1 is very suitable for applications where environmental changes must be accounted for and tight regulation accuracy is necessary. 1N5544BUR-1 is employed in motor and current control, switching power supplies, low-noise amplifiers, optical communication systems, telecommunications and computers.

Working Principle

The working principle of 1N5544BUR-1 is based on the principle of Zener breakdown. When the voltage across the device exceeds the Zener breakdown voltage, the current through the device starts to increase exponentially. This causes the device to regulate the output voltage to remain at a constant value, given enough operating current. The voltage is kept at a precise level, with a maximum tolerance of 0.5V.

At the same time, 1N5544BUR-1 also acts as a voltage clamp device. During an overvoltage condition, the device will regulate the output voltage until it enters the breakdown voltage region and enter the Zener breakdown effect. This method makes it possible to prevent voltage spikes with extremely high precision and provides a very safe, reliable solution in applications which need to protect sensitive components from overvoltages.
