In today's technological age, we live and work with more and more electronic devices. However, transient overvoltages that may exist in the power supply can cause serious damage to these devices. In order to protect electronic devices from overvoltage damage, we need to use TVS transient suppression diodes. Today, Li Yang Semiconductor and you to talk about specific, TVS transient suppression diode!
The role of TVS transient suppression diode
The TVS diode is a specially designed diode that is mainly used to limit transient overvoltage. When the voltage in the system exceeds a set threshold, the TVS diode will quickly switch on, directing the overvoltage to ground to protect other sensitive electronic components. This ability to respond quickly makes TVS diodes ideal for protection of electronic devices.
Second, the working principle of TVS diode
The operating principle of TVS diodes is based on the characteristics of their structure and materials. It is usually composed of a PN structure and has a similar appearance to an ordinary diode. However, TVS diodes use special materials and designs that allow them to withstand high power and transient overvoltages for short periods of time.
When the system voltage is normal, the TVS diode is in a high resistance state and will not have any effect on the circuit. However, when the system voltage exceeds a set threshold, the TVS diode quickly switches to a low-resistance state, forming a current path that guides the overvoltage to ground. In this way, the overvoltage will not have a damaging effect on other electronic components, protecting the entire circuit from damage.
Third, TVS transient suppression diode application
TVS transient suppression diodes are widely used in a variety of electronic equipment and systems, including computers, communication equipment, industrial automation systems, power equipment, etc. In these devices, TVS diodes are often used to protect sensitive electronic components such as chips, sensors, and other important circuit components.
When choosing and using TVS transient suppression diodes, the following factors need to be considered:
1, rated voltage: TVS diode should have enough rated voltage to deal with possible overvoltage situation. The rated voltage should be selected according to the maximum operating voltage of the system.
2, response time: TVS diode should have a fast response time, can quickly turn on and guide overvoltage when overvoltage appears. The shorter the response time, the less damage is done to the device.
3, limit current: TVS diode should be able to withstand transient overcurrent. The limit current depends on the power and design requirements of the equipment.
4, transient energy: TVS diode should be able to deal with transient energy caused by overvoltage. The transient energy is related to the amplitude and duration of the overvoltage.
For TVS transient suppression diode we introduced here, want to know more information can pay attention to Li Yang semiconductor, later we will continue to update!
