Diodes - Zener - SingleThe JAN1N4485D is a single, 5.6V, rated power dissipation of 500mW, glass valve-configured, Zenner diode used in voltage regulation, reverse-relay and latching applications, reference voltage adjustment and overvoltage protection. It offers supreme performance in terms of its stability, reliability and operating parameters, which makes it ideal for use in the majority of industrial and commercial applications.When it comes to the applications of the JAN1N4485D, this device is primarily used in precision voltage regulation, relays and intermediate relays, breakers and regulators, digital circuits, andhigh-speed motor controls. It is also used in various types of electronic applications, such as oscillators, frequency dividers, and logic circuits. Its most common applications include use for low voltage drop voltage switching and clipping, rectification and filtering, clamping and limiting, switching and sensing, and reverse bias protection.The working principle of the JAN1N4485D is quite simple, yet effective. It is a voltage regulator diode that works by regulating an input voltage within a certain range. Essentially, this device works as a barrier that limits the amount of voltage that passes through it. This ability comes from its unique construction, which includes a single p-type region that is sandwiched between two regions of n-type semiconductor material. The thickness of the central p-type region and the doping concentrations of the n-type regions are carefully controlled to ensure optimum voltage regulation performance.When a voltage is applied to the JAN1N4485D, the p-type region acts as a resistor and impedes current flow through the diode. Under normal operating conditions, the central resistance is optimized to limit the current to a maximum of 5.6V. To increase the effectiveness of the protection, the device also provides a low reverse leakage current of 15 µA at room temperature. This makes it very effective in protecting against overvoltage and ensuring peak-to-peak accuracy.In conclusion, the JAN1N4485D is an ideal choice for applications that require precision voltage regulation and minimum leakage current. It is highly reliable and easy to use, and its compact size makes it suitable for a wide range of applications. In addition, its low reverse leakage current ensures that there is minimal risk of damage to sensitive components. Due to its exceptional performance, the use of the JAN1N4485D is becoming increasingly popular in the majority of industrial and commercial applications.
