1N4580A-1

Diodes - Zener - Single

The 1N4580A-1 is a single Zener diode, manufactured using silicon junction technology. It features a case-to-terminal construction, with an anode connection at the center of the case, and a cathode connection at the outside. The diode is designed to regulate a voltage when a current is applied to its cathode side.

The 1N4580A-1 provides a wide range of useful applications in various circuits. It can be used to stabilize voltage in power supply systems, to hold a steady voltage level in AC-DC inverters, and to protect digital equipment such as computers and TVs against surge voltages. It also provides current-limiting or crowbar protection in applications such as battery chargers and telecom power supplies.

The 1N4580A-1 features a relatively high forward voltage drop and a stable zener voltage of 4.008V, making it suitable for voltage regulation in power supplies and other applications. It has reverse leakage current of 1uA and can handle peak power dissipation of 0.75W at an ambient temperature of 25℃.

The working principle of the 1N4580A-1 is based on a Zener break-down effect. When a voltage is applied to the diode, the electrons in the semiconductor crystal will start to move, creating an electric field similar to that of a battery. The electric field will cause the electrons to concentrate on one side of the semiconductor, thus creating a rectifying effect, and allowing the current to flow through the diode in one direction. The Zener breakdown effect takes place when the voltage applied to the diode reaches a certain threshold. At this point, the electric field will reverse, producing a large increase in current, thus providing a regulated voltage.

The 1N4580A-1 is a small, reliable device with many uses in our digital world. It is inexpensive and easy to install, making it a great choice for power supply protection and voltage regulation applications.
