What are the criteria for selecting current limiting diodes and current limiting resistors?

When choosing current limiting diodes and resistors, it is necessary to determine based on the specific requirements and characteristics of the circuit. The following are the differences in the roles of current limiting diodes and current limiting resistors in circuits, as well as the principles for selecting and using them:

What is the difference between current limiting resistors and current limiting diodes in circuits

Although the functions of current limiting diodes and current limiting resistors in circuits are to limit current, their working principles and characteristics are different.

Voltage drop factors of silicon carbide (SiC) diodes

The voltage drop of silicon carbide (SiC) diodes refers to the electromotive force difference of SiC diodes. Silicon carbide diode is a semiconductor device with a P-N junction structure that can be used to control current or voltage. The voltage drop of a diode refers to the electromotive force difference between the P-N junction of the diode in the forward conducting state, that is, the forward bias voltage. This is due to the potential difference between the contact surfaces in the diode.

Instructions for using silicon carbide (SiC) diodes

When using silicon carbide (SiC) diodes, some safety factors should be taken into account, such as avoiding excessive current flowing through the diode to prevent damage. During use, attention should also be paid to circuit design and diode selection to ensure optimal system performance.

The difference between Schottky diodes and silicon carbide Schottky diodes

Schottky diodes and silicon carbide Schottky diodes are two different types of diodes.

Silicon carbide diodes: an important role in the photovoltaic industry

Silicon carbide (SiC) diodes have high stability and efficiency, making them suitable for various photovoltaic applications such as solar panels and solar systems. For example, in solar panels, silicon carbide diodes can prevent excessive current or overvoltage, thereby protecting solar cell components. In solar energy systems, it can also limit the charging current and control the charging and discharging process of the battery.

Detailed explanation of reverse recovery principle of silicon carbide (SiC) diode

Silicon carbide diodes are unipolar devices, so compared to traditional silicon fast recovery diodes (silicon FRDs), silicon carbide diodes have ideal reverse recovery characteristics. When the device switches from forward to reverse blocking direction, there is almost no reverse recovery power, and the reverse recovery time is less than 20ns. Even the reverse recovery time of 600V10A silicon carbide diodes is less than 10ns.

Testing and Inspection Methods for Silicon Carbide (SiC) Diodes

Silicon carbide (SiC) diodes have low switching losses, high reverse withstand voltage, and thermal stability, and have been widely used. Here are the usage and testing methods for SiC diodes:

ESD electrostatic protection layout guide (electrostatic protection diode)

The success of protecting the system from the impact of electrostatic discharge (ESD) largely depends on the design of printed circuit boards (PCBs). Although selecting the appropriate transient voltage suppressor (TVS) is the fundamental approach to ESD protection strategies, it is not within the scope of this article. The technical documentation on ti.com/esd provides many ESD selection guides that can guide you on how to choose the appropriate TVS diode type for a specific system. After selecting the appropriate TVS, using the strategies listed in this ESD Layout Guide to design PCB layouts will provide PCB designers with a successful way to protect the system from ESD impacts.  

Before designing the DC-DC circuit, take a look at the detailed design introduction in this article

In the early days, we all built our own power supply circuits, and now there are many integrated chips. DC-DC circuits are also ubiquitous in electronic products. This article shares some basic knowledge of DCDC circuit design with everyone. Concept and characteristics: DC-DC refers to a direct current to direct current power supply. It is a device that converts electrical energy from one voltage value into electrical energy from another voltage value in a DC circuit.
