Partner of General Hybrid since 1992

Semitron Protection Products, Division of Littelfuse Inc. based in San Diego is specialized in the manufacture of over voltage circuit protection components using in-house technologies and processes.

Rather than limit its product range to a single core technology, Semitron has expanded its horizon by developing other complimentary capabilities so that it can offer a wider range of products and solutions to our customers.

With it focus on overvoltage transient suppressor components, Semitron has built up an extensive knowledge of requirements and specifications covering a wide range of markets including telecom, automotive, computer and general electronics. Semitron is able to assist our customers with design requirements and testing procedure to international standards.

Its test laboratory is equipped to run performance and reliability programmes to international standards and specific customer requirements.
