DSEI2X121-02A Description

Short technical summary and product information.

The DSEI2X121-02A is a fast recovery diode module manufactured by IXYS, designed for high-power applications requiring efficient switching. It integrates two independent standard recovery diodes, each rated for a maximum reverse voltage of 200V and an average rectified current of 123A. The module achieves a fast reverse recovery time of 50ns, enabling reduced switching losses in high-frequency circuits. Forward voltage drop is typically 1.1V at 120A, contributing to low conduction losses.

 

The device is packaged in a SOT-227B (miniBLOC) case designed for chassis mounting, ensuring robust thermal management. It operates over a wide temperature range from -40°C to 150°C, suitable for demanding industrial environments. The two-diode configuration allows flexible circuit topologies such as common-cathode or independent operation.
