Overview
The GBU2K-LV is a low forward voltage single-phase diode bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 2 A and a peak repetitive reverse voltage (VRRM) of 1000 V. The typical forward voltage (VF) is 0.87 V at 25°C with a 2 A current. Peak forward surge current (IFSM) ratings are 135 A for 50 Hz and 150 A for 60 Hz half-sine waves. Thermal resistance from junction to case (RthC) is 3.0 K/W, while junction to ambient (RthA) is 19 K/W. Operating temperatures range from -50°C to +150°C.
Feature Summary
- Low forward voltage design for enhanced power conversion efficiency
- Robust silicon construction supporting high surge current handling
- Wide operating temperature range suitable for demanding environments
Applications
- General-purpose AC to DC power supply rectification
- Battery charger circuits
- Industrial control systems requiring reliable bridge rectification
Procurement Notes
Verify the specific ordering suffix against official Diotec documentation to confirm package type and compliance status. Confirm thermal management requirements align with the specified RthC and RthA values for your application. Ensure mounting torque adheres to the M3 specification of 1 ± 10% Nm or 9 ± 10% lb.in. to prevent mechanical stress on the leads.
Selection Notes
Select this component when low conduction losses are critical in 2 A bridge rectifier applications. Compare the 0.87 V typical VF against standard variants to evaluate thermal performance benefits. Verify that the 1000 V reverse voltage rating exceeds the maximum peak inverse voltage expected in the circuit under all operating conditions.
Part Context
This device belongs to the GBU series of single-phase bridge rectifiers from Diotec Semiconductor. It utilizes a through-hole GBU package configuration designed for robust mechanical mounting. The 'LV' designation indicates a optimized low forward voltage characteristic compared to standard variants within the same current and voltage class.
Replacement Considerations
Check for direct equivalents such as the GBU2K from the same manufacturer family. Verify that any substitute maintains the 2 A current rating, 1000 V reverse voltage, and compatible physical dimensions for PCB mounting.
