A Zener diode is a type of diode that exhibits a very specific behavior when it is exposed to a specific range of voltages. Zener diodes are typically used in circuits that require Voltage Regulation and/or current limiting.The BZX84J-C24,115 is a single Zener diode with a breakdown voltage of 24.0V and Maximum Power Dissipation of 315mW. This diode can withstand a maximum reverse voltage of 24.V and a forward current of 125mA.

Application Field

The BZX84J-C24,115 Zener diode is used in a variety of applications, including voltage regulation and current limiting. In voltage regulation, a Zener diode can be used to protect a circuit from damage due to excessive voltages. This is accomplished by connecting the Zener diode in parallel with a resistor and a power source, with the Zener diode connected in reverse bias. When the voltage input exceeds the Zener voltage, the current will flow through the diode and be dissipated instead of passing through the rest of the circuit. In current limiting applications, the Zener diode can be used to limit the amount of current that passes through a circuit by using it in series with a resistor and a power source. In this arrangement, the diode will allow only an amount of current, equal to its breakdown voltage, to pass through.

Working Principle

The BZX84J-C24,115 Zener diode works on the principle of reverse biased breakdown. In a conventional diode, a small reverse voltage causes a large amount of reverse current to flow, which can result in damage to the circuit. In the Zener diode, however, the reverse voltage is applied in such a way that the junction is not broken and a much smaller reverse current flows. This is called the reverse breakdown and in the BZX84J-C24,115, the breakdown voltage is 24.0V. At voltages above this point, the current increases exponentially and the voltage across the diode also rises, until it reaches its peak at 24.0V.

Once the peak voltage is reached, the Zener diode begins to function as a voltage regulator. Any input voltages higher than the breakdown voltage will be “clamped” to the breakdown voltage, allowing only the amount of current equal to the breakdown voltage to flow. This means that the voltage output from the Zener diode will remain constant and the amount of current passing through the circuit will be limited.

The BZX84J-C24,115 Zener diode is a very useful tool for controlling and regulating the voltage and current in a circuit and is commonly used in a variety of applications. It can be used to protect circuits from excess voltages, limit the amount of current that passes through a circuit, maintain a constant voltage output and even improve the signal-to-noise ratio of audio and video circuits.
