BZX84C20-E3-18

The BZX84C20-E3-18 is a low voltage Zener diode, used to regulate voltage. It has a nominal voltage of 18V, with a tolerance of ±5% and a power dissipation of 200mW. It has a reverse breakdown voltage of approximately 20V.

The diode is designed with a glass-sealed junction, and uses a PN junction to control the voltage, thus allowing only current in one direction to pass through. The BZX84C20-E3-18 has both a low leakage current and a high tolerance for reverse voltages, which makes it useful for many applications.

The BZX84C20-E3-18 can be used as a voltage regulator in circuits, where it limits the voltage to a certain amount. It is used in applications such as power supplies, voltage regulators, electronic line conditioners, and computers. It is also useful for ensuring that low-voltage signals remain declared, and for protecting other components from over-voltage conditions.

The BZX84C20-E3-18 works by using a Zener effect, in which electrons running through a PN junction have the ability to tunnel through the junction, resulting in a lower voltage than the nominal voltage applied to it. This reduces the voltage to a lower, but more acceptable level. The diode also has a high power handling capability, which allows the device to handle high voltage spikes or surges.

The BZX84C20-E3-18 has a wide range of applications in a variety of applications. It is used to regulate voltage in power supplies and voltage regulators, electronic line conditioners, and computers. It can also be used as a voltage limiter in circuits, protecting components from over-voltage conditions. It is also used in laser diodes for laser electronics, and for creating low-voltage signals.

The BZX84C20-E3-18 has many advantages over other Zener diodes, including its low voltage drop, low leakage current, and high tolerance for reverse voltages. This makes it ideal for many applications where a precise and accurate voltage control is needed.
