Single Diodes datasheet and documents for MBR8045R
Single Diodes Overview
The GeneSiC Semiconductor MBR8045R is a silicon power Schottky rectifier housed in a DO-5 (DO-203AB) stud mount package. It features a repetitive peak reverse voltage of 45 V and an average forward current rating of 80 A per package. The device exhibits a maximum forward voltage of 0.75 V at 25 °C and supports a peak forward surge current of 1000 A. Thermal resistance from junction to case is 0.50 °C/W. The 'R' suffix indicates reversed polarity where the stud functions as the anode. Operating and storage temperatures range from -55 °C to +150 °C.
Single Diodes Feature Summary
- High surge capability with robust peak forward surge current handling
- Not sensitive to electrostatic discharge
- Stud mount configuration for efficient thermal management
Single Diodes Applications
- Power supply freewheeling applications
- DC-DC converter circuits
- Inverter and motor drive systems
Single Diodes Procurement Notes
Verify the specific part marking and datasheet revision to confirm the reversed polarity configuration associated with the 'R' suffix. Ensure mounting hardware meets the specified torque requirements for the DO-5 package. Confirm that the thermal interface material and heatsink design support the required junction-to-case thermal resistance for the intended operating environment.
Single Diodes Selection Notes
Select this component when a high-current, low-voltage Schottky rectifier with stud mounting is required. The reversed polarity option allows flexibility in circuit layout where the chassis or heatsink must serve as the anode connection. Consider the 0.50 °C/W thermal resistance for heat dissipation calculations under continuous load conditions.
Single Diodes Part Context
This device belongs to the MBR80 series of silicon power Schottky diodes, which offers ratings from 45 V to 100 V reverse voltage and up to 80 A average forward current. The series utilizes a rugged DO-5 package designed for high-power industrial and automotive applications requiring reliable performance under harsh thermal conditions.
Single Diodes Replacement Considerations
Cross-reference with other MBR80xxR variants for different voltage ratings within the same series. Verify pinout compatibility if substituting with non-reversed polarity versions.
