UDZ11B-7 Discrete Semiconductor Products

The UDZ11B-7 is a single Zener diode designed for applications requiring a stable and low power operated device. The diode has an average forward current of up to 1.3A, a maximum reverse-volt of 5.5V, and a maximum reverse current of 53mA. The UDZ11B-7 is commonly used in low-voltage applications such as protecting against over-voltage transients, in voltage regulator circuitry, and in power supply circuits. Its low power consumption makes it well-suited for high-reliability and low-power applications such as car electronics, mobile phones, and power supplies.

Working Principle

The working principle of a Zener diode is based on the fact that current can flow in both directions through the diode. When forward-biased (a positive voltage is applied to the anode terminal), the UDZ11B-7 functions as a normal diode, allowing current to flow from anode to cathode. When reverse-biased (a negative voltage is applied to the anode), current will flow from the cathode to the anode in the form of a very small reverse current, creating a “broken-down” region. This reverse current is a Zener current, which is regulated and controlled by the Zener voltage.

The Zener voltage is essentially a breakdown voltage of the UDZ11B-7. When the reverse voltage exceeds the Zener voltage, the current flow increases exponentially, allowing the diode to regulate the voltage in the circuit by setting the maximum reverse voltage. For example, if the reverse voltage is 5.5V, the UDZ11B-7 will shunt the excess voltage away and maintain a steady output voltage of 5.5V. This is known as Zener breakdown, or avalanche breakdown.

Application Field

The UDZ11B-7 is commonly used in low-voltage applications to protect circuits from over-voltage transients, as a voltage regulator, and in power supply circuits. It is often used in industrial, automotive, consumer and communication electronics, in particular in low-power and high-reliability applications. The low power consumption of the UDZ11B-7 makes it well-suited for use in mobile phones, car electronics, and in power supplies. Additionally, the UDZ11B-7 is often used in audio devices, current sensors, and other circuits where a precise, stable voltage is needed.

The great advantage of the UDZ11B-7 is its low power consumption, low cost, and high reliability. It is also available in various package types and sizes, making it suitable for a wide range of applications. Furthermore, its low reverse leakage makes it ideal for use in low-power and high-reliability applications.
