The JAN1N4472D is a silicon avalanche Zener diode with a high-temperature, diffused junction and an efficient, non-corrosive passivation. It is designed for applications requiring high reliability and low noise in a wide variety of current, voltage and temperature settings. This diode is suitable for high-temperature applications and is widely used in avionics and space flight electronics.

The JAN1N4472D has a wide range of applications including general voltage regulation, motor control and electronic ignition, overvoltage protection, voltage equalization, overcurrent protection, and AC line and EMI (electromagnetic interference) suppression. It is also suitable for high-temperature environments of up to +175°C. The diode is characterized for a wide range of AC and DC conditions.

The working principle of the JAN1N4472D is based on avalanche breakdown. This breakdown occurs when a certain voltage is applied to the diode, creating a large current flow and releasing a large amount of energy. This energy causes electrons to gain enough kinetic energy to break through the dielectric barrier and avalanche breakdown occurs. The excess energy is dissipated as a combination of resistive and heat losses, resulting in a voltage drop across the diode. This voltage drop reduces the voltage to a safe level, thus providing effective overvoltage protection.

The JAN1N4472D offers several advantages such as a low leakage current, low noise, high reverse breakdown voltage and superior thermal stability. As a result, it is an ideal choice for applications requiring a high level of reliability and low noise in a wide variety of current, voltage, and temperature settings. Furthermore, the diode is manufactured using an efficient, non-corrosive passivation which ensures superior long-term reliability.

In summary, the JAN1N4472D is a highly reliable silicon avalanche Zener diode suitable for applications requiring a wide range of current, voltage and temperature settings. It is characterized for a wide range of AC and DC conditions and is manufactured using an efficient, non-corrosive passivation which ensures superior long-term reliability. Additionally, the diode offers several advantages such as a low leakage current, low noise, high reverse breakdown voltage and superior thermal stability.
