Diodes - Zener - Single

CD0603-Z12 is a series of zener diodes that are mainly used for matching and damping circuit, voltage regulation, signal clamping, and detecting or smoothing electrical noise. It effectively reduces current flow in one direction and allows current to pass in reverse direction when the voltage reaches a certain level.

Application Field

CD0603-Z12 is mainly used in overvoltage protection, clamping protection, noise elimination, signal isolation, and other protection reasons. In power applications, CD0603-Z12 can be used to protect against transient. As CD0603-Z12 is a low-power component, it commonly used in small microprocessors, logical circuits, optocouplers, AC solid state relays and other small circuits. This form of component can also be used in battery powered devices.

Working Principle

When the reverse voltage of CD0603-Z12 reaches a certain level, the current in the diode will flow in reverse direction, because the Zener diode allows a small amount of current to flow in reverse direction and applies reverse voltage as well. This helps to eliminate overvoltage and suppress voltage transient. In AC circuits, it is commonly used in ballast circuits and regulator circuits to rectify the output, stabilizing the circuit and smoothing the output.

CD0603-Z12 can be connected in parallel to increase the current capacity of the circuit, and it can also be connected in series to increase the break-down voltage. Besides, the Zener diode can also be replaced by a transistor circuit to improve the efficiency and linearity, called a Zener diode regulator. For circuits that require higher reverse voltage protection and larger current capacity, CD0603-Z12 may not be suitable.

Conclusion

CD0603-Z12 is a series of zener diodes that are mainly used for matching and damping circuit, voltage regulation, signal clamping, and detecting or smoothing electrical noise. It can also be used in various applications, such as overvoltage protection, clamping protection, noise elimination, signal isolation, and other protection reasons. As CD0603-Z12 is a low-power component, it is mostly used in small circuits. In AC circuits, it is commonly used in ballast circuits and regulator circuits to rectify the output and stabilize the circuit. CD0603-Z12 can be connected in parallel or series to increase current capacity or break-down voltage depending on the circuit requirement.
