Overview
The MDD KBL608 is a through-hole silicon bridge rectifier from the KBL series, featuring a molded plastic body with four pins. It supports a maximum repetitive peak reverse voltage of 800V and an average forward output rectified current of 6.0A at 50°C case temperature. The device withstands a peak forward surge current of 125A for an 8.3ms single half sine-wave. Operating junction and storage temperatures range from -55°C to +150°C. Key electrical characteristics include a typical forward voltage drop of 1.1V at 6.0A, a DC reverse current of 10µA at 25°C, and a thermal resistance (junction-to-ambient) of 20°C/W.
Feature Summary
- Low reverse leakage current capability
- High forward surge current handling
- Guaranteed high-temperature soldering performance
Applications
- Printed circuit board mounting
- General purpose rectification in power supplies
Procurement Notes
Verify that the component matches the original MDD KBL608 specification sheet. Confirm the package type is bulk packaging containing 500 pieces per box. Ensure the part meets RoHS and RoHS III compliance standards as documented in the provided datasheet. Cross-reference the part code KBL6080000L680 to ensure correct identification of the 800V rating and 6A current capacity before procurement.
Selection Notes
Select this component when an 800V reverse voltage rating and 6A continuous forward current are required for through-hole applications. Consider the 20°C/W thermal resistance and 150°C maximum junction temperature for thermal management design. Verify compatibility with printed circuit board mounting requirements and ensure the operating environment falls within the specified -55°C to +150°C temperature range.
Part Context
The KBL608 belongs to the KBL series of thru-hole silicon bridge rectifiers manufactured by MDD. This series includes variants with different voltage ratings such as KBL4005, KBL601, and KBL610. The KBL608 specifically denotes the 800V reverse voltage variant within this family of four-pin molded plastic bridge rectifiers designed for general-purpose rectification tasks.
Replacement Considerations
Compatible substitutes include SECOS KBL608G and other generic KBL608 parts from various manufacturers. Ensure replacement components maintain identical pinout, voltage rating, current capacity, and package dimensions for direct interchangeability.
