DSEI2X61-04C

Diode Arrays Overview

The IXYS DSEI2X61-04C is a Fast Recovery Epitaxial Diode (FRED) housed in an international standard miniBLOC (SOT-227 B) package. It contains two independent FREDs per package with a maximum repetitive reverse voltage of 400 V and a continuous forward current rating of 60 A per diode at 70°C case temperature. The device features a typical reverse recovery time of 35 ns, a maximum of 50 ns, and a peak non-repetitive forward surge current capability of up to 800 A. Thermal resistance from junction to case is specified at 0.7 K/W.

Diode Arrays Feature Summary

• Contains two independent planar passivated chips within a single isolation-compatible package
• Features extremely low switching losses and soft recovery behavior for reduced noise
• Provides high reliability circuit operation with low voltage peaks

Diode Arrays Applications

• Antiparallel diode for high frequency switching devices
• Free wheeling diode in converters and motor control circuits
• Rectifiers in switch mode power supplies (SMPS)
• Snubber diode applications
• Inductive heating and melting systems

Diode Arrays Procurement Notes

Verify the specific ordering suffix matches the required voltage rating, as the DSEI2X61 series includes variants with different reverse voltage capabilities. Confirm that the thermal management design accounts for the specified junction-to-case thermal resistance and power dissipation limits under actual operating conditions. Ensure mounting torque adheres to the manufacturer's specification to maintain proper electrical isolation and heat transfer performance.

Diode Arrays Selection Notes

Select this component when designing circuits requiring fast recovery characteristics with moderate current handling in a standardized panel-mount footprint. The dual independent configuration allows for compact designs in bridge or freewheeling topologies. Evaluate the thermal requirements against the 180 W power dissipation limit and ensure the cooling solution maintains the junction temperature within the specified -40°C to +150°C range during peak load operations.

Diode Arrays Part Context

This part belongs to the IXYS DSEI2X61 series of Fast Recovery Epitaxial Diodes. The series utilizes the miniBLOC package, which is ISOTOP compatible, facilitating interchangeability in existing designs. The DSEI2X61-04C specifically denotes the 400 V variant, distinct from the 600 V rated DSEI2X61-06C model within the same family.
