ESD electrostatic diode ESD92DE005M05-A electrostatic protection application analysis
The best electronic engineer will give priority to the problems in circuit protection circuit design of the initial stage, the analysis of product protection, protection requirements, and according to the actual layout PCB board optimization device, circuit protection devices for later selection is not blocked in the product packaging issues. It can be said that ESD protection, lightning protection design, over-current protection and other puzzles almost every circuit design engineer. In fact, in communications, consumer, military, aerospace and other fields, ESD is often caused by the culprit circuit failure. This small to 0.5pF low capacitance SOD-923 tage electronic package ESD static diode ESD92DE005M05-A as an example, a detailed analysis of ESD electrostatic electrostatic protection diode used in portable devices, mobile phone, digital camera, power and other products in the.

Before the analysis of tage electronic ESD diode ESD92DE005M05-A electrostatic electrostatic protection application, we need to first understand the characteristics of the diode ESD92DE005M05-A ESD electrostatic electronic dance, intimate small series have ESD diode ESD92DE005M05-A parameters of electrostatic finishing well, and look down: ESD92DE005M05-A parameters:

Static impedance ESD specialized in consumer electronic and digital products (electrostatic protection element): voltage range of "24V" 2.5pf, interelectrode capacitance, the response speed is less than 1ns, the leakage current is very low, mainly for the 0603 and 402 package working principle is: in the electrical work process, just ESD for very low capacitance value (usually < 5pf) capacitive characteristics, will not affect the normal electrical characteristics, signal and data and will not affect the transmission of electronic products; over voltage when the device reaches a predetermined voltage at both ends of the collapse, rapid (NS) in response to the amount of geometric series amplifier the leakage current, so as to achieve the absorption and reduce the interference and influence of static electricity on the circuit characteristics. At the same time, because of the particularity of material ESD static impedance, ESD are often through the absorption and dissipation of static electricity, which is shown as a process of charge and discharge, to achieve the electrostatic protection of equipment, so ESD electrostatic impedance devices are not easy to aging damage.
