DSEP2X91-03A Description

Short technical summary and product information.

The IXYS DSEP2X91-03A is a high-performance fast recovery diode module designed for demanding power electronics applications. It contains two independent diodes with a maximum repetitive reverse voltage of 300V and an average forward current rating of 90A per diode. The module offers a typical reverse recovery time of just 40ns at 25°C, enabling efficient high-frequency switching.

 

The diodes feature planar passivated chips for very low leakage current and soft recovery behavior, reducing EMI and switching losses. With a maximum forward voltage of 1.54V at 90A and 25°C, and a typical forward voltage of 1.10V at 150°C, the module maintains good efficiency across temperature. The device is avalanche rated for reliable operation under transient conditions.

 

Packaged in the industry-standard SOT-227B (minibloc) outline, the module features a copper baseplate with internal DCB isolation and an isolation voltage rating of 3000V. The epoxy case meets UL 94V-0 flammability standards. The module is chassis mount and operates over a -40°C to 150°C temperature range, with a maximum power dissipation of 200W.
