Zener diodes are two-terminal, semiconductor devices designed to maintain a stable voltage across their terminals. Zener diodes are capable of maintaining a constant voltage, regardless of the amount of current flowing through the device. The JAN1N4462CUS is an example of a single zener diode in an SOD−123F package.

Application Fields

The JAN1N4462CUS is ideal for a variety of voltage applications. It is used as protection in various power supplies, in which it provides a reliable yet low-cost means of maintaining a stable voltage, regardless of the amount of current flowing through the device. The JAN1N4462CUS is also used to control the voltage of the microcontrollers, memory chips, and other logic circuits in electronic devices such as computers, cell phones, and gaming consoles. Additionally, the device is used to protect circuits from over-voltage or over-current incidents.

Working Principle

The operation of the JAN1N4462CUS is largely dependent on its Zener voltage, which is configured between the two electrodes during the manufacturing process. When a current is applied to the device, the electrons near the interface between the depletion and the active regions of the semiconductor become sufficiently energetic and decay into holes at the interface, generating a depletion region that narrows and eventually depletes. The Zener voltage between the two electrodes forces the flow of current through the device. When the voltage reaches the Zener voltage, the current is clamped down, allowing only a predetermined amount of current to flow through the device. This is the mechanism on which the JAN1N4462CUS device depends to regulate the voltage.

In summary, the JAN1N4462CUS is a single zener diode in an SOD−123F package. It is a reliable, cost-effective solution to controlling and maintaining the voltage of various electronic components, such as microcontrollers, memory chips, and other logic circuits, as well as for protection against over-voltage and over-current incidents. The device works by clamping down current when a predetermined voltage is reached, allowing only a controlled amount of current to pass through.
