What are the transient suppressor diodes? I believe that the transient suppression diode will be some doubt it? Xiao Bian here for everyone to be announced: transient suppression diode is a type of diode in the form of high efficiency protection devices. When the poles of the TVS diode is reverse transient high impact energy, it can with the speed of 10 to the minus 12 second order, variable between the two poles of high impedance to low impedance, the absorption of up to a few kilowatts of power surge, between the two electrodes voltage clamp in a predetermined value, effectively protect the electronic circuit in the yuan precision devices from various surge pulse damage.
Transient suppression diode is for absorbing power surges, withstand voltage reverse impact in a very short period of time, in a specific voltage between the two electrodes voltage clamp, avoid the impact of the back of the circuit. Simple said is overvoltage protection, widely used in computer systems, communications equipment, AC / DC power supply, automotive, electronic ballast converter, the protection of household appliances, instruments and meters (meter), RS232/422/423/485, I / O, LAN, ISDN, ADSL, USB, MP3 players, PDAs, GPS, CDMA, GSM, digital camera, common mode / differential mode protection, RF coupling / IC driver receiving protection, electromagnetic wave interference suppression, audio / video input, sensor / transmission, control circuit, a relay, contactor noise suppression in various fields.
Connection must be reverse work in the circuit power supply, the ground, and the voltage regulator diode similar, but do not need to limit the current resistance.
Because it has a response time is fast, high power transient, leakage current low breakdown voltage deviation, the clamp voltage is easy to control, no damage limit, small volume etc. advantages.
