MDS35/ 50 / 80Series

DIODE / SCR MODULE

December 2000 - Ed: 4

MAIN FEATURES:

DESCRIPTION

Packaged in ISOTOP modules, the MDS Series is

based on the half-bridge SCR-diode configuration.

They are suitable for high power applications,

using phase controlled bridges, such as soft-start

circuits,

welding

equipment,

motor

speed

controller. The compactness of the ISOTOP

package allows high power density and optimized

power bus connections. Thanks to their internal

ceramic pad, they provide high voltage insulation

(2500V RMS), complying with UL standards (File

ref: E81734).
