BZD27C82P-HE3-18

The BZD27C82P-HE3-18 is a single diode, which belongs to the category of Zener Diodes. It is used for a variety of applications, depending on the specific characteristics of the diode. It has a breakdown voltage of 18 Volts. The main purpose of this diode is to provide a stable voltage source for circuits requiring a reliable reference voltage.

When using this diode, it is important to be aware of its limitations. This diode has max current ratings of 150mA, meaning that it should not be used in circuits that require higher currents. It has a relatively low reverse voltage leakage when forward biased, meaning that it is less than ideal for use in circuits requiring higher reverse voltages.

The BZD27C82P-HE3-18 operates by exploiting the concept of avalanche breakdown. This occurs when the reverse voltage of a diode reaches a certain level, and is caused by a large number of carriers being swept across the junction due to the electric field effect. This avalanche of carriers causes the diode to break down, resulting in a low voltage drop across the diode when in the reverse biased state. This allows the diode to provide a stable reference voltage in static circuits.

The BZD27C82P-HE3-18 can be used in a variety of applications. One use is in series regulator circuits, where the diode is used to provide a stable output voltage. This diode can also be used in voltage limiting circuits, where it can be used to protect other circuit components from unsafe voltages. This diode can also be used in voltage clamp circuits to limit the maximum voltage achieved in a circuit.

The BZD27C82P-HE3-18 can also be used in switching and amplifying circuits. In these applications, it can be used to create a fixed reference voltage, allowing for the creation of more complex circuits. This diode can also be used in voltage and current regulating circuits, providing a consistent supply of voltage and current to other circuit components.

In summary, the BZD27C82P-HE3-18 is a single Zener Diode that is used in a variety of circuits, depending on its characteristics. It exploits the concept of avalanche breakdown in order to provide a reference voltage in static circuits, and can be used to limit voltages, regulate current, and amplify and switch signals.
