Advantages of TVS Diodes

Power Circuit Protection

TVS Diodes when compared to Varistor and Zener technology offer the following advantages:

  1. Faster Response
  2. Lower Clamping Voltage
  3. Lower ESD Energy

    Both varistors and zeners respond more slowly to an ESD event and have a much higher clamping voltage when compared to TVS diodes. This will result in a lot more undesired ESD energy entering the system, which is why these technologies are primarily used for higher power protections than for higher speed ESD applications.
