Overview
The KBL04 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor, designed for printed circuit board mounting. It features a plastic-passivated junction and silver-plated leads within the KBL case style. The device supports a maximum repetitive peak reverse voltage of 400 V and a maximum average forward current of 4.0 A at 50 °C ambient temperature. Peak forward surge current capability reaches 200 A under single sine-wave conditions superimposed on rated load. The component operates across a junction and storage temperature range from -50 to +150 °C.
Feature Summary
- High surge current capability
- Plastic-passivated junction construction
- High case dielectric strength of 1500 V RMS
Applications
- AC/DC bridge full wave rectification in monitors
- TV sets and printers
- Switching mode power supplies (SMPS) and adapters
- Audio equipment and home appliances
Procurement Notes
This component has reached its End of Life status. The last available purchase date was July 30, 2025. Procurement must be completed before this deadline as no further production or supply is guaranteed. Verify compliance documentation and material categorization details through official Vishay channels prior to finalizing any acquisition plans.
Selection Notes
Select the KBL04 when a 400 V reverse voltage rating is required alongside a 4 A continuous forward current capacity. Ensure the application environment accommodates the specified operating temperature range of -50 to +150 °C. Consider the thermal resistance characteristics relative to the intended PCB copper pad size and lead length for adequate heat dissipation during operation.
Part Context
The KBL04 belongs to the KBL series of single-phase bridge rectifiers, which includes variants with different voltage ratings such as KBL005, KBL01, KBL02, KBL06, KBL08, and KBL10. All members share the same physical KBL package outline and mechanical data, differing primarily in their maximum repetitive peak reverse voltage specifications.
Replacement Considerations
Direct substitutes include other KBL series parts like KBL02 or KBL06 if voltage requirements differ. Cross-brand replacements must match the 4 A current rating, 400 V blocking voltage, and KBL package dimensions.
