Diodes - Zener - Single

The JAN1N4955C diode is a single Zener diode featuring small size, low cost, and a big power rating, making it suitable for use in a wide range of applications. The diode is designed to allow regulated current to flow through it, providing a continuous and high output voltage.

Structure

The JAN1N4955C Diode is constructed to be compliant with JEDEC standards and uses an encapsulating SOD-123 package, allowing it to be used in high energy, automotive, and military applications. The diode comprises a silicon PN junction, and an anode and cathode terminal connection. The anode has a higher positive voltage potential, compared to the cathode terminal with a lower negative voltage potential.

Working Principle

The working principle of the JAN1N4955C diode is simple. When a current higher than the Zener voltage is applied to the PN junction, a Zener breakdown occurs, allowing a stable flow of current across the diode. While the diode is designed to have a breakdown voltage of 5.1V (± 5%), thanks to its zener junction it can hold up to 24V. This is why it is suitable for a large number of applications.

Applications

The JAN1N4955C Diode is typically used in voltage regulation and polarity reversal applications. It can also be used in devices such as computers, automotive systems, and industrial equipment, where it serves as a voltage regulator. Additionally, its resistance to transient voltage makes it a suitable choice for flyback circuitry in LED driver applications.

Given its low cost, small size, and high power rating, the JAN1N4955C diode can be utilized in a number of different applications. With its ability to provide a continuous and stable output voltage, it can help ensure the safety and reliability of various electronic systems.
