JAN1N4980C Datasheet/PDFThe JAN1N4980C is a silicon zener diode capable of reliably producing an accurate and stable voltage reference that is temperature and current compensated. It is a necessary component that is used in diverse applications to respond to output voltage fluctuations, over-voltage spikes, and high voltage load conditions. This article will provide an overview of the JAN1N4980C’s various applications and working principle.
Applications
The JAN1N4980C is commonly used in a wide range of applications and industries, including automotive, industrial, military, and medical. Its application examples include forming transient voltage suppressors in automobiles, helping buffer radio-frequency transceiver circuitry, protecting relays for power supply circuits, and providing reference voltages for microprocessor and digital circuitry.
The JAN1N4980C’s capability to produce stable and accurate voltage reference is also of special appeal to sensitive electronic components like semiconductors. Because these sensitive electronic components are sensitive to any form of current fluctuation or impedance in the power supply, having a voltage regulator like the JAN1N4980C can help provide an extra layer of protection and maintain reliability.
The most important feature of JAN1N4980C is its capability to provide quick response to output voltage fluctuations and over-voltage spikes. This helps protect sensitive electronic components from any form of thermal damage or breakdown. Due to its ability to self-regulate and withstand higher voltage, the JAN1N4980C is used in applications such as radio-frequency (RF) transmitters and receivers, power supply circuits, data systems, and other consumer electronics devices.
Working Principle
The JAN1N4980C is comprised of a semiconductor layer composed of n-type and p-type silicon materials. The semiconductor material is kept in an intrinsic state that prevents any carriers from being generated, allowing the device to act as a voltage regulator. Each JAN1N4980C also contains a zener junction formed by breaking the intrinsic silicon layer with a heavily doped pn junction.
When the current flows through the device, the heavily doped junction acts as a diode, preventing current from flowing forward. If the device is then subjected to reverse voltage, the electrons in the heavily doped junction are injected into the intrinsic layer, creating a current flow and regulating the voltage to a predetermined level. This is how the JAN1N4980C can act as a voltage regulator and protect sensitive electronic components.
The JAN1N4980C is also temperature and current compensated, meaning it is designed to maintain a consistent and precise output voltage regardless of changes in temperature or current. This helps the device maintain output voltage stability and reliability for the lifetime of the component.
In summary, the JAN1N4980C is a versatile and reliable component used in various industries. It is designed to provide accurate and stable voltage reference, protect sensitive electronic components from voltage fluctuations and over-voltage spikes, and to self-regulate in temperature and current to maintain output voltage stability.
