It is widely used in consumer electronics products, telecommunication systems, medical systems, instrumentation systems, and other consumer electronics, industrial and military components. The device is also suitable for use in automotive applications, power supplies and electric power. It can also be used in AC/DC circuits, DC/DC converters, field-effect transistors, thyristors and IGBTs.

Working Principle

The UDZSTE-1727B is a single Zener diode with a reverse leakage current that decreases as the voltage increases. This diode is designed to have a sharp reverse characteristics, enabling/disabling capability and a large safe operating area. This diode can handle currents up to 100mA and can supply a voltage of 1.8V to 18V. When a voltage greater than the Zener voltage is applied to the diode, large current outputs result. This current is used to regulate the output voltage, allowing for the precise control of the various parameters in the circuit.

The device works in accordance with the PN junction theory, which basically means that a junction between two different types of materials allows electrons to pass in one direction. With the device, the total current is the sum of the forward current and the current it supplies to maintain its Zener voltage. In most applications, the diode will be connected inversely, meaning that the diode will conduct current in the direction of the Zener voltage and supply a voltage reference to other elements of the circuit.

The overall performance of the UDZSTE-1727B is dependent on its temperature coefficient, which affects the device’s ability to regulate voltages accurately. The diode features a temperature coefficient of 5mV/°C, which is significantly lower than other devices. This allows the device to accurately monitor and control voltages at a wide range of temperatures.
