Overview
The GeneSiC Semiconductor 150KR40A is a silicon standard recovery diode in the DO-8 package. It features a repetitive peak reverse voltage of 400 V and a continuous forward current rating of 150 A. The device exhibits a forward voltage of 1.33 V at Tj = 25 °C and an I²t fusing value of 58,000 A²sec for an 8.3 ms pulse. Thermal resistance from junction to case is 0.25 °C/W. Operating and storage temperatures range from -55 °C to 150 °C.
Feature Summary
- High surge capability with robust non-repetitive forward current handling
- Not sensitive to electrostatic discharge
- Standard polarity configuration with stud as cathode
Applications
- General purpose rectification
- Industrial power conversion
- Inverter circuits
Procurement Notes
Verify the specific part number suffix against official documentation to confirm terminal configuration. Standard versions utilize a cathode stud, while 'R' variants feature reversed polarity with an anode stud. Confirm RoHS compliance status and ensure the selected variant matches the required thermal management and mounting specifications for the target application environment.
Selection Notes
Select this component for applications requiring high current handling and rugged performance in harsh environments. The low thermal resistance facilitates efficient heat dissipation through the stud mount. Ensure the system design accommodates the specified maximum operating temperature and provides adequate mechanical clamping force for the threaded stud interface to maintain optimal thermal contact.
Part Context
This device belongs to the 150K(R) series of silicon standard recovery diodes manufactured by GeneSiC Semiconductor. The series covers voltage ratings from 200 V to 1000 V, all sharing a common 150 A current rating and DO-8 package form factor. The 'R' designation indicates a reversed polarity option within the same family.
Replacement Considerations
Direct substitutes include other 150 A, 400 V silicon standard recovery diodes in the DO-8 package. Verify that alternative parts match the 0.25 °C/W thermal resistance and 1.33 V forward voltage characteristics to ensure equivalent circuit performance and thermal management requirements are met.
