KBL01

Overview

The KBL01 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor, utilizing the KBL case style. It provides a maximum repetitive peak reverse voltage (VRRM) of 100 V and supports a maximum average forward current (IF(AV)) of 4.0 A at an ambient temperature of 50 °C. The device features a peak forward surge current capability of 200 A and a maximum instantaneous forward drop of 1.1 V at rated load. Operating junction temperatures range from -50 °C to +150 °C, with a typical thermal resistance from junction to lead of 4.0 °C/W.

Feature Summary

• Plastic-passivated junction construction for enhanced reliability
• High case dielectric strength rated at 1500 V RMS
• UL recognition under file number E54214
• Silver-plated leads compatible with standard soldering processes

Applications

• AC/DC bridge full wave rectification in monitors
• Power supply units within televisions and printers
• Switch-mode power supplies (SMPS) and adapters
• Audio equipment and general home appliances

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm compliance with RoHS standards and material categorization requirements prior to integration. Validate that the specific lot matches the documented electrical characteristics and physical dimensions outlined in the official datasheet.

Selection Notes

Select this component when a 100 V reverse voltage rating and 4 A continuous current capacity are required for PCB-mounted applications. Ensure the design accommodates the specified thermal resistance values and operating temperature limits. Evaluate the package dimensions against available board space constraints before finalizing the selection.

Part Context

This component belongs to the KBL series of single-phase bridge rectifiers, which includes variants with different voltage ratings such as KBL005, KBL02, KBL04, KBL06, KBL08, and KBL10. All members share identical mechanical footprints and thermal characteristics while differing primarily in their maximum repetitive peak reverse voltage specifications.

Replacement Considerations

Direct substitutes include other Vishay KBL series parts with matching voltage ratings. Cross-manufacturer equivalents must be verified for identical pinout configurations, current handling capabilities, and thermal performance metrics.
