CZRW55C11-G

Diodes - Zener - Single

CZRW55C11-G is a type of single Zener diode. Zener diodes are two-terminal voltage regulators which exploit the significant voltage drop across the diode when it is connected in a reverse bias. Single Zener diodes are suitable for use in voltage-regulation applications where current requirements are minimal.

Application Field

CZRW55C11-G Zener diodes are designed to be used as voltage references or voltage shunt for feature-rich designs. This diode can be used in different electrical systems to maintain the voltage level from power supply fluctuations, such as in a power supply circuit. It also can be used in current/voltage limiting, voltage stabilizing as well as for protection against power surges.

Working Principle

CZRW55C11-G Zener diodes operate by allowing current flow between their two terminals, an anode and a cathode, by forming an electrical “bridge” between them. The diode has an inherent voltage level, typically between 2-6V, which is above the reference voltage level. When the voltage across the diode reaches this level, it allows the current flow to occur. This action serves to stabilize the voltage, ensuring that it remains at the reference level as long as the applied voltage remains above the Zener voltage.

In addition to providing regulation services, Zener diodes can also be used to protect sensitive electronics from damage when the voltage significantly increases above the reference level. When the voltage on one side of the diode reaches its Zener voltage, the diode quickly conducts current and dissipates any excess energy. This protects the circuit by preventing incorrect voltages from damaging sensitive components.

Conclusion

CZRW55C11-G is a type of single Zener diode. It can be used in a variety of applications, such as voltage-regulation, current/voltage limitation, voltage stabilization, and protection against power surges. It works by allowing current flow through a diode when the applied voltage reaches the Zener voltage of the diode. This action serves to stabilize the output voltage and also to protect the circuit from any excessive voltage surges.
