GSI Ltd - Semiconductors

GSI are a broad line distributor who offers a complete sourcing solution, with an extensive product profile ensuring a total purchasing strategy.

GSI was founded in 1996 as a distributing firm specialising in LED and Opto products. Growing rapidly, GSI soon began to broaden its product range, branching into discrete semiconductors and transient suppression. The flexibility and innovation of GSI has enabled us to react quickly to changes in markets and technical requirements, resulting in us being equipped to service a far wider commercial market.
