Epcos has added the CDS4C12GTA type to its CeraDiode range for ESD protection.
Measuring 2.5 x 0.8 mm, the new type has the same solder pad dimensions as TVS diodes in SOD-223 packages and can be used as a drop-in replacement for more expensive diodes.
Apart from low cost, the device offers bidirectional overvoltage protection with low leakage current at the same time.
It also features short response times of less than 0.5 ns and no degradation at temperatures up to 85°C.
Due to its stable capacitance, the diode can be used as an EMI filter as well as for ESD protection.
Another product in the CeraDiode family is the CDA5C16GTH, a high-speed Cera Diode quad array in size 0612.
Its self-capacitance is 3 pF. Signal distortion is prevented on lines with high data rates, such as USB 2.0, Firewire, ethernet and video applications.
