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.
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.
The SMAJ-HP6AT and 1.5SMBJ-AT series have applications ranging from industrial to automotive, lighting to communication, and their excellent characteristics make the new series of TVS diodes the best choice.
A diode is an electronic component made of semiconductor material that has a single conductivity, allowing only current to pass in one direction. A diode is composed of two different doped semiconductor materials, usually silicon (Si) or germanium (Ge). Among them, the side with high doping concentration is called the P-type region, and the side with low doping concentration is called the N-type region. The materials in the P-type zone mainly use trivalent elements, such as boron (B); The materials in the N-type zone mainly use pentavalent elements, such as phosphorus (P).
