Overview
The GeneSiC Semiconductor GBU15K is a single-phase glass passivated silicon bridge rectifier designed for high-current applications. It features a GBU package with an average forward rectified current (IO) of 15 A and a repetitive peak reverse voltage (VRRM) of 800 V. The device supports a maximum forward voltage drop (VF) of 1.05 V at 7.5 A and withstands a peak forward surge current (IFSM) of 250 A. Operating temperatures range from -40 °C to +150 °C, with thermal resistances of 5.0 °C/W (junction-to-case) and 22 °C/W (junction-to-ambient).
Feature Summary
- Glass passivated chip junctions ensure reliable operation under high temperature conditions.
- Epoxy resin body meets UL 94V-0 flammability standards for enhanced safety.
- High surge overload rating provides robustness against transient current spikes.
Applications
- Printed circuit board mounting for power supply units.
- General purpose rectification in industrial equipment.
- AC to DC conversion in consumer electronics.
Procurement Notes
Verify the manufacturer designation on the component marking, as multiple entities produce this series. Confirm RoHS compliance status through official documentation before integration. Ensure the specific suffix matches the required voltage rating for the target application circuit design.
Selection Notes
Select the GBU15K when an 800 V blocking voltage is required alongside a 15 A continuous current capacity. Consider the thermal resistance values for heatsink sizing if operating near maximum ratings. Verify that the GBU package dimensions fit the available PCB layout constraints.
Part Context
This component belongs to the GBU15J through GBU15M series of single-phase bridge rectifiers. The series shares identical mechanical dimensions and current ratings, differing primarily in their voltage blocking capabilities. The GBU15K specifically denotes the 800 V variant within this standardized product family.
Replacement Considerations
GBU15J serves as a lower voltage alternative (600 V). GBU15M offers a higher voltage rating (1000 V). Both share the same 15 A current rating and physical footprint, allowing for direct pin-compatible substitution if voltage margins permit.
