TDK Product Features

TDK's comprehensive portfolio covers the whole range of voltage protection devices which are used to guard IC components and electronic circuits from electrostatic discharges (ESD) and voltage surges such as lightning surges. The lineup includes CeraDiodes©, chip protectors, chip and disk varistors as well as gas-filled surge arresters. Current protection devices, such as NTC inrush current limiters and PTC thermistors, are used to protect circuits from inrush currents and overcurrents. Temperature protection devices such as PTC thermistors and chip NTC thermistors are used to protect internal circuits or devices from overheating.
