Overview
The GeneSiC Semiconductor 150KR20A is a silicon standard recovery rectifier diode housed in a DO-8 stud mount package. It features a repetitive peak reverse voltage of 200 V and a continuous forward current rating of 150 A at a case temperature of 25 °C. The device exhibits a maximum forward voltage of 1.33 V and a surge non-repetitive forward current capacity of 3740 A under half-sine wave conditions. Thermal resistance from junction to case is specified at 0.25 °C/W, supporting operation within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- High surge current capability for robust transient handling
- ESD insensitive design for simplified handling
- Standard polarity configuration with cathode stud
Applications
- Industrial power conversion systems
- General purpose rectification circuits
- High current DC power supplies
Procurement Notes
Verify the specific suffix designation against official documentation to confirm terminal polarity. Standard versions utilize a cathode stud, while 'R' variants feature reversed leads with an anode stud. Confirm mounting hardware compatibility with the 3/8-24 UNF thread specification prior to integration into assembly lines.
Selection Notes
Select this component for applications requiring high current density in a compact stud-mount form factor. Ensure thermal management strategies maintain the case temperature below 110 °C to sustain the rated 150 A continuous current. Evaluate system voltage requirements against the 200 V blocking capability to ensure adequate safety margins during normal operation.
Part Context
This part belongs to the 150K(R) series of silicon standard recovery rectifiers manufactured by GeneSiC Semiconductor. The series spans voltage ratings from 200 V to 1000 V, all sharing a common 150 A current rating and DO-8 package footprint. This standardization facilitates mechanical interchangeability across different voltage levels within the same product family.
Replacement Considerations
Cross-reference mechanical dimensions and electrical parameters when substituting. Verify that alternative components support the required 3740 A surge current and match the 0.25 °C/W thermal resistance specification.
