Diodes - Zener - Single
CMOZ18V TR is a silicon planar power zener diode with a rated voltage of 18V and an environment-friendly lead-free process. It can be widely used in voltage stabilization and reference in DC power supplies and low-power DC circuits.
CMOZ18V TR has a relatively low rated Zener voltage and is primarily used in the production of low-voltage, low-power electronic products. It is mainly used to form a regulated power supply circuit, and is also used in IC timing and control circuits, voltage limiters, voltage clampers, lightning impulse withstand voltage and other circuits.
Working principle
The working principle of CMOZ18V TR can be divided into two parts: forward conduction and reverse conduction.
In the forward conduction state, CMOZ18V TR acts as an ordinary diode and acts as a normal diode to control the direction of the current and to prevent the current from flowing out of the component and into the power line. In the reverse conduction state, when the reverse voltage across the terminals of the component exceeds the Zener voltage, it will cause the component to start conducting current in the reverse direction, and the component will be in a Zener state.
The reverse breakdown voltage of CMOZ18V TR is 18V. When the reverse voltage across the component reaches this voltage or exceeds it, breakdown occurs. At this time, the reverse saturation current of the component increases sharply and causes the component to enter the conducting state. Under this condition, the reverse current of the component is relatively stable, and the voltage drop across the component terminals is also relatively constant.
Application field
CMOZ18V TR can be widely used in DC power supplies, low-power DC circuits, voltage stabilization, reference, IC timing and control circuits, voltage limiters, voltage clampers, and lightning impulse withstand voltage protection. It is mainly used in the production of low-voltage, low power electronic products.
In addition, it can be used in the following application fields:
- Voltage regulators
- Voltage monitor circuit
- DC-DC converters
- Voltage references
- Protection circuits for power supplies
CMOZ18V TR has the advantages of low cost and environment friendly process, making it an ideal solution for these applications.
Conclusion
CMOZ18V TR is a silicon planar power Zener diode with a rated voltage of 18V and environment-friendly lead-free processes. It has a relatively low rated Zener voltage and can be widely used in voltage stabilization, reference, IC timing and control circuits, voltage limiters, voltage clampers, and lightning impulse withstand voltage protection. It has the advantages of low cost and environment friendly process, making it an ideal choice for these applications.
