The 5SDD0120C0200 is a high-current disc-type rectifier diode for industrial rectifier applications. It features a low forward voltage drop, low thermal resistance, and surge current capability, making it applicable for high-power rectifiers, welding equipment, electrolysis systems, and industrial power conversion applications.
High forward current capability
Low forward and reverse recovery losses
Medium frequency range, typ. up to 2 kHz
This hermetically sealed ceramic hockey-puck component operates with a repetitive peak reverse voltage of 200 V and handles a maximum average forward current of 11,000 A under specified thermal conditions. The silicon chip configuration functions within medium-frequency inverter power supplies up to 2000 Hz while limiting power dissipation under full load. The pinless and studless structural design uses flat upper and lower copper faces as both electrical contacts and thermal interfaces, requiring a mechanical clamping force between 35 kN and 40 kN for double-sided mounting between water-cooled or air-cooled heatsinks.
