Diodes - Zener - Single

1N4763UR-1 diode is a Zener diode operated with a single voltage, specifically a 4.7V Zener voltage. It is a two-terminal, general-purpose device specifically designed to provide tight zener tolerance on both test and v-i characteristics. The device also provides high reliability and temperature stability.

Application Field

1N4763UR-1 has a wide range of applications. It is popularly used as a voltage regulator in order to maintain voltage drop and also for overvoltage protection. It can be used for noise suppression circuitry and in stabilizing a constantly fluctuating voltage. It is also used in surge protection and transient voltage suppression, protecting circuits from voltage spikes, spikes resulting from high power switching loads, power inductors, high-speed switching loads, or a combination thereof. Lastly, 1N4763UR-1 can also be used as replacements for germanium diodes in long-life applications.

Working Principle

A Zener diode, like a normal diode, will allow current to flow in 1 direction. However, they also have a unique characteristic that sets them apart from the normal diode — they can also allow current to flow in the opposite direction. This occurs when the device has been stressed beyond the Zener breakdown voltage (Vz max). Once this voltage has been reached, the device’s resistance to current decreases rapidly and allows current to flow in the opposite direction.

When voltage is applied to the diode and it is below the Zener voltage (Vz max), current will flow through the diode as in a normal diode due to the forward-bias applied to the device. However, if the voltage is greater than the Zener voltage (Vz max), current will start to flow in the opposite direction due to the reverse-bias applied to the device. This reverse-biased current will keep the voltage at the Zener voltage (Vz max), regardless of changes in the applied voltage. This is why Zener diodes are commonly used in voltage regulation applications.

1N4763UR-1 offers a high quality in various applications with its features such as low noise, temperature stability, and reliability. Due to its ease of use, it is becoming a preferred choice in numerous electronic circuits. Its unique characteristic of allowing two-way conduction and limiting current flow to a pre-determined level allows it to be useful in various applications such as power management, surge protection, and noise suppression.
