KBL02

Overview

The KBL02 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor, designed for general-purpose AC/DC full-wave rectification. It features a maximum repetitive peak reverse voltage (VRRM) of 100 V and supports a maximum average forward current (IF(AV)) of 4 A at an ambient temperature of 50 °C. The device exhibits a peak forward surge current (IFSM) capability of 200 A and maintains a maximum instantaneous forward voltage drop (VF) of 1.1 V at rated current. Operating junction temperatures range from -50 °C to +150 °C, with a typical thermal resistance (RθJA) of 19 °C/W.

Feature Summary

• Plastic-passivated junction construction providing high case dielectric strength of 1500 V RMS
• High surge current capability suitable for demanding transient conditions
• UL recognition (file number E54214) ensuring compliance with safety standards
• Silver-plated leads optimized for solderability per J-STD-002 and JESD22-B102

Applications

• AC/DC bridge full wave rectification in monitors and televisions
• Power supply units within printers and switching mode power supplies (SMPS)
• Rectification circuits in audio equipment and home appliances

Procurement Notes

Verify the specific manufacturer designation before procurement, as the component is produced by Vishay General Semiconductor rather than onsemi. Confirm that the End of Life status does not conflict with long-term production requirements. Ensure the selected variant matches the required voltage rating and package dimensions for the target PCB layout.

Selection Notes

Select this component when a 100 V reverse voltage rating and 4 A continuous current capacity are required for compact printed circuit board applications. Evaluate the thermal resistance characteristics against the expected operating environment to ensure junction temperatures remain within the specified limits during continuous operation.

Part Context

The KBL02 belongs to the KBL series of single-phase bridge rectifiers, which includes variants ranging from 50 V to 1000 V reverse voltage ratings. This series utilizes the KBL case style, characterized by its inline configuration and suitability for surface mounting on standard PCBs. The family shares common mechanical and electrical design principles across different voltage grades.

Replacement Considerations

Direct substitutes include other Vishay KBL series components such as KBL04 or KBL06 if higher voltage ratings are acceptable. Cross-manufacturer equivalents should be verified for matching IF(AV), VRRM, and physical footprint dimensions to ensure compatibility with existing assembly processes.
