G D Rectifiers supply heatsink assemblies which are manufactured to order. GD Rectifiers are able to supply the complete range of traditional and state-of-art power semiconductors to customers together with technical support for operation and use of these components within the customer equipment circuits. Additionally the Company has a standard range of power conversion control assemblies incorporating the above components mounted on proprietary heat dissipating extrusions (heatsink assemblies) which are manufactured to order.In-house design and manufacture of customised power semiconductor equipment is also undertaken to customer specifications. GD Rectifiers are the industry leader in heatsink assemblies,selenium rectifiers and suppressors
Since 1963 GD Rectifiers has designed and manufactured selenium and silicon rectifiers and suppressors for power control applications. It has evolved to be still a leading force today in the same industry sector using current state-of-art technologies. GD employs qualified and innovative technical personnel to assist customers through design and component specification phases. This is particularly useful when our specialist product division considers a solution. GD Rectifiers develops bespoke power control assemblies for international markets, and stocks and distributes power components throughout the UK. The company additionally operates a repair and replacement service with faulty or ageing rectification equipment. The services page enables you to select an area of interest. .

Power Semiconductors - Franchised and Own Brand G D Rectifiers holds stock of encapsulated single and three phase rectifiers for AC/DC conversion circuits. For the same application it holds converter grade discrete and module thyristors. Motor drive and inverter OEM's can draw from inventory of inverter grade thyristor capsules and for more contemporary designs an extensive range of insulated gate bipolar transistors (IGBT's) as well as Power mosfet modules or discretes in smaller packages. Fast recovery epitaxial diodes can feature in most of these above circuits for a freewheeling or HF rectification function, as can schottky diodes, both of which are stocked.Mosfet, IGBT and Fred Schottky transistors all stocked aswell as parts from Westcode, Semikron, IXYS, EDI and Sirio.

Manufactured Units The Company offers a short turn-round for standard single and three phase rectifiers, diode or thyristor, with integral heatsinks in either bridge or AC regulator (soft start) configuration. Where required, these units can incorporate fuses, snubbers and/or suppressors and can be either naturally or fan cooled. Customised heatsink assemblies - open or enclosed - can be designed with appropriate control or protection features for specific purposes and interfaced to be integral with the users processing system. Standard and Custom Selenium Rectifiers and Suppressors can be manufactured to order for purposes where these components offer the optimum solution.
