LB6SL

Overview

The Good-Ark Semiconductor LB6SL is a low-profile miniature single-phase surface mount bridge rectifier designed for general-purpose AC-DC rectification. It features glass passivated standard diodes within an ABF package, offering a maximum average output rectified current of 1.0 A and a maximum repetitive peak reverse voltage of 600 V. The device supports a peak forward surge current of 30 A and operates across a junction temperature range of -55°C to +150°C. Electrical characteristics include a typical instantaneous forward voltage of 1.0 V at 1.0 A and a maximum DC reverse current of 5.0 µA at rated blocking voltage.

Feature Summary

• Glass passivated standard bridge rectifiers ensuring reliable performance
• Halogen-free construction compliant with IEC 61249-2-21 definition
• Moisture sensitivity level 1 per J-STD-020 standards
• Plastic package with Underwriters Laboratory flammability classification 94V-0

Applications

• General purpose AC-DC bridge rectification in power supplies
• Charger applications
• Telecom device applications

Procurement Notes

Verify the specific part number suffix against manufacturer documentation to confirm halogen-free status, as the datasheet indicates adding an "E" suffix denotes halogen-free variants. Confirm package type ABF dimensions and taping orientation requirements during procurement to ensure compatibility with automated assembly equipment. Cross-reference thermal resistance values for PCB mounting conditions.

Selection Notes

Select the LB6SL when a 600 V peak reverse voltage rating is required for single-phase rectification with a 1.0 A continuous current load. Consider the ABF surface mount package for space-constrained designs requiring low profile components. Ensure the operating environment stays within the specified -55°C to +150°C junction temperature range and verify soldering parameters do not exceed 260°C for 10 seconds.

Part Context

The LB6SL belongs to the LBxSL series from Good-Ark Semiconductor, which includes variants ranging from LB1SL to LB10SL. This series covers reverse voltages from 100 V to 1000 V while maintaining a consistent 1.0 A output current capability. All members share the same ABF surface mount package and electrical characteristics except for voltage ratings.

Replacement Considerations

Direct substitutes within the same series include LB4SL (400 V) or LB8SL (800 V) if voltage margins allow. Verify that alternative bridge rectifiers match the 1.0 A current rating, ABF package footprint, and thermal resistance specifications to ensure mechanical and electrical compatibility.
