The BZX84C18-7-F is a single Zener diode from Panasonic. It features a low voltage rating of 7V, a power dissipation of 0.5W, and a forward current of 1A.

Application Field

The BZX84C18-7-F is a popular choice in circuits which require a low 1V threshold. It is ideal for applications such as voltage regulation, voltage protection, and protection against transients. It is also used in switch mode power supplies, AC adapter circuits, and other low voltage DC circuits.

Working Principle

The operation of the BZX84C18-7-F is based on Zener break down, which occurs when the reverse voltage of the diode is increased above a certain level. When the reverse voltage exceeds this level, the diode breaks down, causing current to pass through the diode.

The reverse voltage at which the BZX84C18-7-F breaks down is known as the Zener voltage. In the case of this diode, the Zener voltage is 7V. The current which passes through the diode is known as the Zener current, which is limited by the maximum forward current rating of 1A. When the reverse voltage is dropped, the current flow stops.

The BZX84C18-7-F is an ideal diode for applications which require low voltage protection. It is able to withstand high transient voltages and limit their effect on the circuit. It is also able to regulate the voltage within a precise range.
