Overview
The GBU4K-LV is a low forward voltage single-phase diode bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 4 A and a peak forward surge current (IFSM) of 200 A at 50 Hz or 220 A at 60 Hz. The device has a maximum repetitive peak reverse voltage (VRRM) of 1000 V and a typical forward voltage (VF) of 0.87 V at 25°C with 4 A current. Thermal resistance from junction to ambient is 21 K/W, while junction to case is 3.3 K/W. Operating temperatures range from -50°C to +150°C for both junction and storage.
Feature Summary
- Low forward voltage design for improved efficiency
- High surge current capability for robust operation
- Wide operating temperature range up to 150°C
Applications
- AC-DC power supply circuits
- Battery chargers
- General-purpose rectification in industrial equipment
Procurement Notes
Verify the specific ordering suffix and packaging configuration directly with Diotec Semiconductor or authorized distributors before placing orders. Confirm RoHS compliance status and lead times through official channels. Ensure that the procurement documentation matches the exact part number GBU4K-LV to avoid receiving standard variants without the low Vf characteristics.
Selection Notes
Select this component when reduced conduction losses are critical in 4 A bridge rectifier applications. Verify that the thermal management design accommodates the specified junction-to-ambient thermal resistance. Ensure the circuit's peak reverse voltage requirements do not exceed the 1000 V rating under all operating conditions.
Part Context
This component belongs to the GBU series of single-phase bridge rectifiers from Diotec Semiconductor. The LV designation indicates a low forward voltage variant optimized for efficiency compared to standard versions in the same package family.
Replacement Considerations
Standard GBU4K models may exhibit higher forward voltage drops. Verify compatibility if substituting with other manufacturers' GBU packages, ensuring equivalent IFAV, VRRM, and thermal performance metrics are met.
