6 Typical Applications

Protection diodes are required in many industrial and automotive applications for a wide variety of interfaces, such as CAN bus and USB. They can be used to protect other active components such as MOSFETs and transistors, or to discretely regulate voltage. When deciding between zener, ESD, and TVS diodes to protect a circuit, consider the following questions. How fast is the interface and what line capacitance is required? Does the circuit require overvoltage protection and what clamping voltage level is desired? How much power could the diode have to dissipate? What IEC ESD and surge levels are needed? The following section provides common circuit examples for zener, ESD, and TVS protection diodes.
