B72214P2 – Compact and High-Performance Metal Oxide Varistor

TDK Corporation has presented B7221P2*, a compact S14 AdvanceD-MP series of metal oxide disk Varistors that features smaller dimensions with the same excellent performance as compared to S14 types. The Disk Varistors are designed with a diameter of 13mm to 14mm which is comparatively a 3mm reduction. Similar to their current S14 counterparts, these Varistors also offer maximum surge current capability of 6 kA at 8/20 µs according to IEC 62368-1. The optimized design of the Varistors results in an improved derating performance over time.


Features of B7221P2 MOV:

  • High performance with a smaller disk diameter
  • Wide operating voltage range from 130 to 460 VRMS
  • All types duty cycle @ 6 kV/ 3 kA = >10 pulses
  • Multiple pulse handling capability

Note: More technical information can be found at the datasheet linked at the bottom of this page


The compact size and outstanding electrical characteristics of the Varistors allows the design engineers to reduce the size of their products, hence they can be used in a wide range of applications. All the types of Compact S14 /Varistors are approved by UL, CSA, VDE, and IEC. These Varistors can be used in power supplies as the primary protection against low-level repetitive surge currents and other applications such as switch-mode power supplies, drivers for LED lighting, home appliances, and smart meters.
