SMD 2220 Ultra-High Energy Varistor | Surge Protection for Power and New Energy Systems

The SMD 2220 Series Metal Oxide Varistors are large-package surface-mount protection devices designed for high-energy surge absorption and strong current suppression in industrial and power electronic systems. Measuring 5.7 × 5.0 mm, they feature excellent energy capacity, low leakage, high reliability, and sub-nanosecond response time. Ideal for AC line input, power buses, EV BMS, and high-frequency inverters. 

SMD 2220 Series is widely applied in heavy-duty surge protection for:

  • AC main input of power modules
  • EV BMS, motor controllers, and battery pack protection
  • Industrial UPS, high-frequency inverters, and ESS systems
  • Telecom base station power lines and outdoor lightning SPD units
  • Distribution box SPD modules and energy gateway interfaces
  • Smart meters and busbar surge management in grid equipment
