            The difference between the TVS diode and zener diode
            Publish:Shenzhen Tergy Technology Co., Ltd.  Time:2016-12-26
            The difference between the TVS diode and Zener diode:
            TVS diode and zener diode can be used as the regulator, but the Zener Current is smaller than 10V, the voltage is only 1mA, relatively zener diode breakdown current to a lot, but the zener diode voltage accuracy can be done relatively high.
             
              TVS diode:
            TVS diode
             
            Is a high-performance protective device diode form; English callsign TVS is Chinese South TV; TVS or Transvaginal Ultrasonography English (transvaginal ultrasonography): common in ultrasound examination report.
            TVS is a high-performance protective device diode form. When the TVS diode poles by the reverse transient high energy impact, it can be minus 12 seconds speed of 10 magnitude, the high impedance between the poles into the low impedance, absorb up to several kilowatts of power surge, the voltage clamp between two poles at a predetermined value, precision components for effective protection support in the electronic circuit, the pulse surge from damage. Because it has fast response, transient power, low leakage current, breakdown voltage of small deviation, the clamp voltage is easy to control, no damage to the limit, the advantages of small size, have been widely used in computer, communication equipment, AC / DC power supply, automobile, electronic ballasts, household appliances, instrumentation (meter) I/O, LAN, RS232/422/423/485, ISDN, ADSL, USB, MP3, PDAS, GPS, CDMA, GSM, digital camera, protection, differential protection, RF / common mode coupling /IC driver receiving protection, motor electromagnetic interference suppression, audio / video input, sensor / transmission, control circuit, relay and contactor noise the inhibition of other fields.
             
              Voltage stabilizing diode:
            Voltage stabilizing diode

            English name Zener diode, also called zener diode. By using the PN junction reverse breakdown state, the current can be changed in a large range and the voltage is basically unchanged. The [1] diode is a semiconductor device until the critical breakdown voltage before has very high resistance. In this critical breakdown point, reverse resistance is reduced to a very small value, in the low resistance region in current increases while the voltage is kept constant, is classified according to the zener diode breakdown voltage. Because of this characteristic, the regulator is mainly as a regulator or voltage reference element. The zener diode can be connected in series to be used on a higher voltage, and a higher stable voltage can be obtained through series connection.
            The positive characteristic of the zener voltage characteristic curve is almost the same as that of the common diode. The reverse characteristic is that when the reverse voltage is lower than the reverse breakdown voltage, the reverse resistance is very large, and the reverse leakage current is very small. However, when the reverse voltage is close to the critical value of the reverse voltage, the reverse current suddenly increases, which is called breakdown. At this critical breakdown point, the reverse resistance suddenly drops to a small value. Although the current varies in a large range, the voltage at both ends of the diode is substantially stable near the breakdown voltage, thereby achieving the diode‘s voltage stabilization function.
