KBF410

Overview

The Good-Ark Semiconductor KBF410 is a glass-passivated single-phase bridge rectifier designed for general-purpose AC-to-DC full-wave rectification. It features a maximum average rectified output current of 4.0A and a maximum repetitive peak reverse voltage (VRRM) of 1000V. The device utilizes a KBF molded plastic case with matte tin-plated leads, ensuring solderability and compliance with UL 94V-0 flammability ratings. Key electrical characteristics include a maximum instantaneous forward voltage of 1.1V at 4A and a maximum DC reverse current of 200µA at rated blocking voltage. The component supports a junction temperature range from -55°C to +150°C and offers high surge current capability suitable for PCB mounting.

Feature Summary

• Glass passivation provides stable performance and protection against chemical damage
• High surge current capability ensures reliability during transient load conditions
• Halogen-free construction meets environmental safety standards
• Moisture sensitivity level 1 rating simplifies storage and handling requirements

Applications

• AC-to-DC bridge full wave rectification in TV and monitor power supplies
• Switching mode power supply (SMPS) input stages
• Adapter and printer power circuits
• Audio equipment and home appliance control boards

Procurement Notes

Verify the specific part number KBF410 against official Good-Ark Semiconductor documentation to confirm the 1000V reverse voltage rating. Ensure that procurement specifications align with the KBF package outline dimensions and terminal plating requirements. Confirm compliance with RoHS and halogen-free definitions prior to ordering.

Selection Notes

Select the KBF410 when a 1000V reverse voltage rating is required for single-phase bridge rectification applications. Consider the 4.0A continuous current capacity and the thermal resistance values for heatsinking decisions. Verify that the operating environment remains within the specified -55°C to +150°C junction temperature range for optimal device longevity.

Part Context

The KBF410 belongs to the KBF401-KBF410 series of glass-passivated single-phase bridge rectifiers manufactured by Good-Ark Semiconductor. This series covers reverse voltage ratings from 100V to 1000V while maintaining a consistent 4.0A output current capability. The components share identical mechanical dimensions and electrical characteristics except for the voltage rating, allowing for design flexibility across different voltage requirements.

Replacement Considerations

Compatible substitutes include other single-phase bridge rectifiers with a minimum 1000V VRRM, 4.0A IF(AV), and compatible KBF or similar DIP-4 package footprint. Verify that replacement devices meet the same forward voltage drop and reverse leakage current specifications to ensure circuit performance parity.
