Multilayer varistors combine overvoltage, electrostatic discharge (ESD), and electric fast transient protection in a single, surface mount device. these ultra-low–profile surge protective devices typically protect printed circuit board and integrated circuit components. Because multilayer varistors perform more than one function, they can replace several larger discrete surge suppressors and signal filtering devices on PCBs. Littelfuse offers several types of multilayer varistors, including devices specifically designed for use in passenger cars and commercial vehicles.
- Wide range of voltage ratings (e.g., 3.5 V to 48 V)
- Very low to low capacitance (e.g., 3 pF to 22 pF)
- Inherently bidirectional clamping
- Meet IEC 6100-4-2 standards for electromagnetic compliance
- Automotive devices meet AEC-Q200 standards
- RoHS compliant
- Can be used to protect analog and digital circuits
- Specifically designed to mount on the surface of PCBs
- Compatible with reflow and wave soldering procedures
- Operate in a wider temperature range than do Zenner diodes
- Reduce need for discrete surge protective devices
- Absence of plastic housings translates into smaller footprints and higher UL flammability ratings
