KBL10

Overview

The KBL10 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor, belonging to the KBL series. It features an in-line circuit configuration within the KBL case style. The device supports a maximum repetitive peak reverse voltage of 1000 V and a maximum DC blocking voltage of 1000 V. It provides a maximum average forward current of 4.0 A at 50 °C ambient temperature and handles a peak forward surge current of 200 A. Key electrical characteristics include a maximum instantaneous forward drop of 1.1 V at 4.0 A and a maximum DC reverse current of 5.0 μA at 25 °C. The operating junction and storage temperature range spans from -50 °C to +150 °C.

Feature Summary

• High surge current capability for robust performance under transient loads
• Plastic-passivated junction structure ensuring long-term reliability
• High case dielectric strength rated at 1500 V RMS for enhanced isolation
• UL recognition (file number E54214) confirming safety compliance

Applications

• AC/DC bridge full wave rectification in monitors
• Power supply units for televisions and printers
• Switching mode power supplies (SMPS)
• Audio equipment and home appliances

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches required packaging and compliance standards. Check the datasheet revision date against manufacturing lot codes to ensure alignment with current specifications. Validate that the product status aligns with project lifecycle requirements before finalizing procurement plans.

Selection Notes

Select this component based on the 1000 V reverse voltage requirement and 4 A continuous current rating. Ensure thermal management strategies account for the specified thermal resistance values. Verify that the PCB layout accommodates the KBL package dimensions and mounting torque limits. Consider the operating temperature range to guarantee performance stability across the intended application environment.

Part Context

The KBL10 is part of the KBL series of single-phase bridge rectifiers produced by Vishay General Semiconductor. This series includes variants with different voltage ratings ranging from 50 V to 1000 V. All members share the same physical KBL package outline and similar electrical characteristics regarding current handling and thermal properties, differing primarily in their peak reverse voltage capabilities.

Replacement Considerations

Direct substitutes within the same Vishay KBL series include KBL08 (800 V), KBL06 (600 V), and other lower voltage variants if system constraints allow. Cross-manufacturer replacements must match the 4 A current rating, 1000 V voltage rating, and KBL package footprint. Verify pinout compatibility and thermal resistance parameters before implementation.
