BZX84W-C56F Application Field And Working Principle

The BZX84W-C56F is a single Zener diode of the DO-35 type package. It is used mainly in the fields of uninterruptible power supplies and frequency inverters. It has an extremely wide range of operating temperature, ranging from -55 to + 175 degrees C.

The Zener diode has a distinct behavior compared to that of a normal diode. It doesn\'t have a junction gap which causes current to stop flowing when the voltage reaches a certain value. The Zener diode has a drastically different characteristics in that when the reverse voltage reaches the so-called Zener voltage, the diode allows a small current to pass through it in the reverse direction - the Zener effect.

The BZX84W-C56F has a Zener voltage of 5.6 volts and a Zener current of 300 mA. The maximum reverse voltage can reach up to 12V and the Maximun power dissipation is 1 Watt. The diode also has an ultra-low forward voltage drop of 0.5 volts.

The working principle of the BZX84W-C56F is that when the diode is connected to a voltage source with a voltage higher than or equal to the Zener voltage, then the Zener voltage serves as the clamping voltage and controls the current flow through the diode.

The working of the BZX84W-C56F can be broken down in three stages:

• 1. The diode is in the reverse biased state, with the applied voltage lower than the Zener voltage.
• 2. When the applied voltage is greater than the Zener voltage, the diode is pushed into the breakdown region of its characteristic curve and it starts to conduct current in the reverse direction.
• 3. The Zener voltage of the diode acts as the voltage clamp and the diode limits the current passing through it.

The BZX84W-C56F has several advantages over other types of Zener diodes, such as its low Zener voltage and low breakdown voltage, as well as its wide range of operating temperature. It is also relatively inexpensive compared to other Zener diodes, and it is easy to assemble due to its DO-35 type package.

In conclusion, the BZX84W-C56F is a single Zener diode of the DO-35 type package which can be used in the fields of uninterruptible power supplies and frequency inverters. It has a wide range of operating temperature, a low Zener voltage, and a relatively low breakdown voltage. Its working principle consists of three stages, and it has several advantages over other types of diodes, such as its wide range of temperature, low prices and easy to assemble.
