Concord Semi
Full Product Range

Transient Voltage Suppression Diode Devices

Concord Semiconductor was a leading Taiwan-based designer and manufacturer of TVS diodes and other overvoltage circuit protection products that protect equipment from high voltage/high energy transients. Littelfuse acquired Concord Semiconductor, based in Taiwan, in 2006.


Concord’s line of TVS diodes and overvoltage circuit protection products are used in numerous markets including automotive, consumer electronics, computer, industrial and telecommunications.

Why Concord Semiconductor?

Concord added silicon manufacturing capabilities in Taiwan and China to Littelfuse, which were later transferred to our new production facility in Wuxi, China.  The acquisition also brought additional TVS diode sales to Littelfuse, expanding our product offerings and strengthening our position in the circuit protection industry.
