Diodes – Zener – Single - BZV55C12-TP Application Field and Working Principle

BZV55C12-TP is a single Zener voltage regulator diodes widely used in various power and electronic circuits. Its rated Zener voltage and maximum Zener current are 12V and 200mA respectively. It is characterized by low reverse current leakage, high power dissipation and excellent temperature stability. This diode is designed to regulate local voltages, maintain and protect supply voltages, and can also be used in reverse power applications such as buck boost regulators and AC/DC converters, dynamic brakes and motor control.

Typical Applications

• Voltage regulation and clamping in DC power supply circuits;
• Regulation of dynamic braking voltage on motors;
• Relay and contactor switching;
• Switch-mode power supply circuits;
• Noise and load transient clipping.

BZV55C12-TP is mainly used in DC power supply circuits, and are suitable for applications where positive and negative switching performance is required. It is also used in communication systems, computers, and industrial and consumer products. The diode has a wide range of applications in automotive, aerospace, and military systems as well.

Working Principle

BZV55C12-TP acts as a voltage regulator because of its Zener effect which is a property of certain semiconductor materials to exhibit a sharp increase in the reverse current when a specified threshold voltage is exceeded. When the voltage across the Zener diode reaches its Zener voltage, VZ, the PN junction junction turns on and the reverse current, IR, through the diode increases exponentially. The amount of current flowing through the diode depends on the voltage applied to the diode and the characteristics of the PN junction forming the diode.

The Zener diode maintains a very stable voltage drop across it in both forward and reverse direction. When the voltage is below its Zener voltage, the diode acts as an ordinary forward-biased semi-conductor device and passes only a very small current. As the input voltage increases and exceeds the Zener voltage, the current through the diode increases exponentially. This current is limited by the connected circuit and is set equal to the Zener current, IZ. The working principle of the Zener diode simply states that the voltage across the diode remains relatively constant at the Zener voltage regardless of the current that may flow through it provided that the current is kept below the maximum operating power dissipation.

Conclusion

The BZV55C12-TP is a single Zener voltage regulator diode suitable for use in varied applications ranging from DC power supply and voltage regulation in industrial, automotive, aerospace and military systems to noise and load transient clipping in communication systems and computers. The diode utilizes the Zener effect to regulate the voltage across it. This enables it to maintain a very stable voltage at its threshold voltage and ensures that the current flowing through it remains within the safe limits of working power dissipation.
