Diotec Minibridge Replaces Four Discrete Diodes

March 09, 2006 by Jeff Shepard

Low cost input rectification for small power supplies has been up to now accomplished by using four discrete rectifier diodes. The newly developed SMD outline "SuperMicroDIL" by Diotec offers space and weight saving at a comparable cost to discrete solutions. The parts named MS40 to MS500 feature an output current of as much as 0.5 Amp at a maximum reverse voltage of 1,000 Volts. This makes them suited for battery chargers, off-line power supplies and compact fluorescent lamps, but also for auxiliary power supplies in home appliances and industrial applications.

The package outline is fully compatible to the industry standard TO-269AA ("MiniDIL"), enabling the SuperMicroDIL to be used on existing SMD bridge rectifier layouts. The pin distance of 2.5 mm fulfills all creapage and clearance requirements, the extremely low device height of only 1.6 mm allows for building up ultra low profile assemblies.
