Transient voltage suppressor (TVS) is a high-efficiency protection device in the form of diode. When the two poles of TVS diode are impacted by the reverse transient high energy, it can change the high impedance between the two poles into low impedance at a speed of the order of 10 minus 12 power seconds, absorb the surge power up to several kilowatts, clamp the voltage between the two poles at a predetermined value, effectively protect the precision components in the electronic circuit from various surge pulses.
Because the transient diode has the advantages of fast response time, large transient power, low leakage current, breakdown voltage deviation, easy control of clamp voltage, no damage limit, small size and so on.
Now it has been widely used in computer systems, communication equipment, AC / DC power supply, automobiles, electronic ballasts, household appliances, instruments and meters (watt hour meters), RS232 / 422 / 423 / 485, I / O, LAN, ISDN, ADSL, USB, MP3, PDAs, GPS, CDMA, GSM, digital camera protection, common mode / differential mode protection, RF coupling / IC drive receiving protection, motor electromagnetic wave interference suppression, audio / video input, sensor / transmission Industrial control loop, relay, contactor noise suppression and other fields.
