DSI2X55-16A Description

Short technical summary and product information.

The IXYS DSI2X55-16A is a dual rectifier diode module designed for high voltage and high current applications. It contains two independent standard recovery diodes in a single SOT-227B (miniBLOC) package, enabling easy chassis mounting with M4 screw terminals.

 

Key electrical ratings include a maximum repetitive reverse voltage (VRRM) of 1600V per diode and an average forward current of 56A per diode at a case temperature of 80°C with a 180° sine wave conduction angle. The module can handle a maximum RMS forward current of 120A and offers high surge current capability — up to 700A (60Hz, 8.3ms, 45°C). The typical forward voltage is 1.2V at 60A and 25°C.

 

The SOT-227B package provides isolation voltage of 2500V RMS, ensuring safe operation in line-connected circuits. Thermal resistance from junction to case is rated at 0.65 K/W, and the module weighs 30 grams. This component is suitable for input rectifier stages, UPS systems, and inductive heating equipment.
