Overview
The GBU10K-LV is a low forward voltage single-phase diode bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 10 A and a repetitive peak reverse voltage (VRRM) of 1000 V. The typical forward voltage drop (VF) is 0.87 V at 25°C with a 10 A load. Peak forward surge currents are rated at 200 A for 50 Hz and 220 A for 60 Hz half-sine waves. The device operates within a junction and storage temperature range of -50°C to +150°C, with thermal resistances of 2.7 K/W (junction-to-case) and 18 K/W (junction-to-ambient).
Feature Summary
- Low forward voltage design for enhanced efficiency.
- High surge current capability for robust protection.
- Wide operating temperature range suitable for demanding environments.
Applications
- General-purpose AC to DC power supply conversion.
- Industrial electronics requiring reliable rectification.
- White goods and consumer appliance power circuits.
Procurement Notes
Verify the specific ordering suffix against official Diotec documentation to confirm package type and compliance status. Ensure that the selected component meets the required electrical ratings for the target application environment. Cross-reference datasheet parameters with actual circuit requirements before finalizing procurement decisions.
Selection Notes
Select this component when a standard bridge rectifier requires reduced conduction losses. The low VF characteristic makes it suitable for applications where thermal management is critical. Verify that the 1000 V reverse voltage rating exceeds the maximum expected line voltage peaks in the system design.
Part Context
This part belongs to the GBU series of single-phase bridge rectifiers from Diotec Semiconductor. The GBU series utilizes a molded plastic case designed for through-hole mounting on printed circuit boards. The 'LV' designation specifically indicates a low forward voltage variant optimized for improved energy efficiency compared to standard versions.
Replacement Considerations
Check for direct replacements within the GBU series offering similar current and voltage ratings. Verify pinout compatibility and physical dimensions if substituting with components from other manufacturers. Ensure thermal resistance characteristics match the existing heat dissipation design.
FAQ
What is the typical forward voltage drop at full load?
The typical forward voltage drop is 0.87 V at a junction temperature of 25°C and a forward current of 10 A.
How does the surge current rating vary with frequency?
The peak forward surge current is rated at 200 A for a 50 Hz half-sine wave and 220 A for a 60 Hz half-sine wave.
What is the recommended protective resistance calculation?
The protective resistance Rt is calculated as VRRM divided by IFSM to ensure the surge current limit is not exceeded during capacitor charging.
