TDK Corporation unveils two innovative varistor series in SMD design, catering to diverse applications with their high surge current capabilities. The newly launched B72210M and B72214M series offer a broad operating voltage range from 175 VRMS to 460 VRMS, equivalent to 225 VDC to 615 VDC.

Designed to meet stringent requirements, the B72210M series delivers a surge current capability of 6000 A, while the B72214M series boasts an impressive 10,000 A surge current capability. Both series are engineered to withstand high operating temperatures up to +125 °C and challenging damp heat environments (85% relative humidity at +85 °C).

Qualified to AEC-Q200 standards, these varistors come in horizontal and vertical versions, enhancing design flexibility for various applications. The horizontal variants measure 22 x 15 x 11 mm and 27 x 18 x 11 mm (L x W x H) for the B72210M* and B72214M* series, respectively. Meanwhile, the vertical types feature dimensions of 15 x 10 x 20 mm and 18 x 10 x 25.5 mm.

The introduction of these SMD high surge varistors addresses the needs of industries such as on-board chargers, power supplies, frequency converters, photovoltaic systems, and household appliances. Their compact design enables space-saving benefits compared to leaded varistors without compromising performance, offering a reliable solution for surge protection in demanding environments.
