Diodes - Zener - Single - CZRFR18VB-HF application field and working principle

CZRFR18VB-HF diodes are special types of single Zener diodes, which are fed by a regulated voltage source. The CZRFR18VB-HF diode is capable of regulating the output voltage of a regulated voltage source, allowing some flexibility in design of power supplies and other applications where a specific voltage is needed. This article will cover CZRFR18VB-HF application field, working principle and its advantages for such application.

CZRFR18VB-HF application field:

CZRFR18VB-HF single Zener diodes are mainly used in power and signal circuits, such as:

• Low-voltage DC power supply
• Regulating high-voltage power supplies
• Vi-bridge rectifier (VBR) circuits
• Calibration of high-precision oscillators
• Voltage stabilizer
• Harmonic filters
• Temperature control circuits
• Inductive load circuits

CZRFR18VB-HF Working principle:

The CZRFR18VB-HF Zener diode works on the principle of avalanche breakdown which occurs when a diode is reverse biased above a certain voltage. This condition is called Zener breakdown, and this voltage is referred to as the Zener voltage. At the Zener breakdown voltage, the diode is designed to provide a relatively constant voltage output, regardless of current or temperature conditions.

The typical operating voltage range of the CZRFR18VB-HF is 6-30V. This means that when the reverse voltage applied to the diode exceeds 6V, the device will start to conduct and its potential barrier breakdown. The Zener voltage Vz is the voltage at which the avalanche breakdown of the diode occurs. The Zener voltage of the CZRFR18VB-HF diode is nominally 18V.

The Zener diode acts as a voltage regulator because of its breakdown voltage which remains relatively constant over a wide range of currents and temperatures. This is because the current through the diode is determined by the voltage applied to it, not the other way round. Therefore, the output of a Zener diode can be used to maintain a constant voltage in a power supply.
