FEATURES : SCR/REGEN Topology 600V Rated Voltage 300A Continuous IGBT Current Internal Zener Clamps on Gate Proprietary Encapsulation Provides Near Hermetic Performance MIL-PRF-38534 Screening Available (Modified) Light Weight Domed ALSIC Baseplate Robust Mechanical Design for Hi-Rel Applications Ultra-Low Inductance Internal Layout Withstands 96 Hours HAST and Thermal Cycling (-55°C to +125°C) MIL-PRF-38534 CERTIFIED DESCRIPTION : The MSK 4890 is one of a family of plastic encapsulated modules (PEM) developed specifically for use in military, aerospace and other severe environment applications. The SCR/REGEN configuration and 600 volt/300 amp rating make it ideal for use in high current motor drive and inverter brake applications. The Aluminum Silicon Carbide (Al Si C) baseplate offers superior flatness and light weight; far better than the copper or copper alloys found in most high power plastic modules. The high thermal conductivity materials used to construct the MSK 4890 allow high power outputs at elevated baseplate temperatures. Our proprietary coating, SEES™ - Severe Environment Encapsulation System - protects the internal circuitry of MSK PEM's from moisture and contamination, allowing them to pass the rugged environmental screening requirements of military and aerospace applications. .. MSK PEM's are also available with industry standard silicone gel coatings for a lower cost option. EQUIVALENT SCHEMATIC TYPICAL APPLICATIONS Motor Drives Inverters 1 Rev.
