LB2010S

Overview

The LB2010S is a general-purpose bridge rectifier manufactured by Good-Ark Semiconductor, designed for AC to DC conversion. It features glass passivation and an ABF plastic package rated UL-94V-0. The device supports a maximum repetitive peak reverse voltage of 1000 V and a maximum average output rectified current of 2.0 A. Key electrical parameters include a typical instantaneous forward voltage of 1.1 V at 2 A and a maximum DC reverse current of 100 µA at rated blocking voltage. It operates within a junction temperature range of -55°C to +150°C and withstands a peak forward surge current of 80 A.

Feature Summary

• Glass passivated structure provides high reliability and stable performance under varying conditions.
• ABF epoxy package meets UL-94V-0 flammability classification for safety compliance.
• Halogen-free construction adheres to IEC 61249-2-21 definitions for environmental standards.

Applications

• General purpose AC to DC bridge rectification in power supplies
• Charger circuits for consumer electronics
• Office appliance power management systems
• Home appliance control boards
• Telecom device power modules

Procurement Notes

Verify the component authenticity against the official Good-Ark Semiconductor datasheet specifications. Confirm that the received parts match the ABF package outline dimensions and marking codes (2010S). Ensure storage conditions comply with J-STD-020 moisture sensitivity level 1 requirements before soldering to prevent package damage during assembly.

Selection Notes

Select the LB2010S when a 1000 V reverse voltage rating is required alongside a continuous 2.0 A load current. This model is suitable for applications demanding high thermal stability up to 150°C junction temperature. Consider the ABF surface-mount footprint for automated placement processes requiring compact board layouts.

Part Context

The LB2010S belongs to the LB20xS series of general-purpose bridge rectifiers from Good-Ark Semiconductor. This family includes variants ranging from 100 V to 1000 V reverse voltage ratings, all sharing the same 2.0 A current capacity and ABF package form factor. The series is engineered for cost-effective mass production in standard consumer and industrial electronic assemblies.

Replacement Considerations

Compatible substitutes include other 1000 V, 2.0 A bridge rectifiers in the ABF package, such as the MB10F or KBPC1001, provided pinout compatibility and thermal resistance characteristics are verified against the original design constraints.
