MSAD200-08

Overview

The Microsemi MSAD200-08 is a glass passivated rectifier diode module with an average forward current rating of 200 A at a case temperature of 100°C. It features a maximum repetitive reverse voltage of 800 V and a non-repetitive peak surge current of 6800 A at 10 ms. The device utilizes an aluminum oxide ceramic isolated metal baseplate for heat transfer, providing electrical isolation up to 3000 V rms. Key thermal characteristics include a junction-to-case resistance of 0.21 °C/W per diode and a junction operating temperature range from -40°C to 150°C.
