KBL005

Overview

The KBL005 is a single-phase silicon bridge rectifier manufactured by Vishay General Semiconductor, housed in the KBL surface-mount package. It provides a maximum average forward current of 4.0 A at an ambient temperature of 50 °C and supports a peak forward surge current of 200 A. The device features a maximum repetitive peak reverse voltage (VRRM) of 50 V and a maximum DC blocking voltage of 50 V. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V at rated current and a reverse leakage current of 5 μA at 25 °C. The component operates within a junction and storage temperature range of -50 °C to +150 °C.

Procurement Notes

Verify the specific ordering suffix, such as -E4/51, to confirm RoHS compliance and commercial grade classification. Note that the datasheet indicates this product line has reached End of Life status, with the last available purchase date specified as July 30, 2025. Confirm availability through authorized distributors before finalizing procurement plans.

Selection Notes

Select the KBL005 when a 50 V reverse voltage rating is required for single-phase rectification. Ensure the design accommodates the 4.0 A average forward current limit at 50 °C ambient temperature. Consider the thermal resistance values provided for heatsink or PCB mounting scenarios to maintain junction temperatures within the specified 150 °C maximum operating limit.

Part Context

The KBL005 belongs to the KBL series of single-phase bridge rectifiers from Vishay General Semiconductor. This family includes variants with different voltage ratings, such as the KBL01 through KBL10, all sharing the same physical KBL package style and 4.0 A current handling capability. The series is designed for general-purpose rectification tasks requiring compact surface-mount solutions.

Replacement Considerations

Direct replacements within the same manufacturer family include other KBL series variants like the KBL01, KBL02, KBL04, KBL06, KBL08, and KBL10, which share identical mechanical dimensions and current ratings but offer higher voltage capabilities.
