About Us

Mark 5 Limited is a distributor of Far Eastern, North American and European semiconductors, specialising in discrete components such as IGBT power modules, transistors, thyristors and FETs.

Based just outside Portsmouth on the south coast of England, Mark 5 Ltd was formed in 1993 by an ex-Purchasing Manager who, having been in the industry since 1963, recognised the need for an independent distributor who could supply obsolete and non-supported semiconductors without a large minimum order requirement.

Mark 5's warehouse inventory stands at 44,539 stock lines with 2,440,833 components on the shelves (a massive 235,008 stock lines and 244,910,930 components when counted with our range of affiliates and partners) and consists of

It is supported by a vast database of almost every component ever produced.

In addition to Mark 5's huge stock of components, the company is able to source devices from all over the world using its close relations with a vast number of international suppliers.

Mark 5's customer base varies from service departments who require small quantities of components immediately to major manufacturers who require an ongoing supply of one or two discrete components on an allocation or schedule basis.
