BZX79-C15,113 Application Field and Working Principle

The BZX79-C15,113 is a zener diode characterised by its higher current handling capability and low voltage drop ideal for voltage regulation, current limitation, and surge over-voltage protection applications. It is able to function as a voltage regulator, current regulator, or surge protector, and can also be used in noise management and filtering applications.

Application Fields

The BZX79-C15,113 is widely used in all kinds of general-purpose applications, such as for communications and security systems, as well as for various industrial applications. It is most commonly used in circuit protection applications and in low noise management, such as for television and radio receivers, audio systems, and video production.

It is also used in transient voltage suppression, for car and commercial vehicle electronics, for high-frequency power supplies, and for various automotive applications including airbags and engine controllers. In addition, the diode’s tight voltage regulation makes it an ideal component for on-board automotive electronics.

Working Principle

The BZX79-C15,113 is a zener diode, which means it employs the zener effect to allow current to flow in one direction only. This is achieved by creating a junction between two doped semiconductor pieces, resulting in a heavily doped N-type region to the left of the P-type region. When a voltage is applied in the N-type region, a reverse voltage will be developed across the junction. When this happens, the current starts to flow through the junction in the reverse direction, resulting in a voltage drop due to the process known as the zener effect.

The BZX79-C15,113 is a one-way current limiting device, meaning it can be used to regulate or limit the amount of current in a circuit. The voltage across the diode is kept relatively constant, and the current is limited to the designated value. As a result, the BZX79-C15,113 is an ideal component for reliable circuit protection and noise management.
