Overview
The EIC KBL408 is a single-phase silicon bridge rectifier featuring glass passivated chips. It provides a maximum average forward current of 4.0 A and a peak reverse voltage of 800 V. The device supports a peak forward surge current of 120 A under half-sine wave conditions. Electrical characteristics include a maximum forward voltage of 1.05 V at 2 A and low reverse leakage currents of 10 µA at 25 °C. The component operates within a junction temperature range of -55 to +150 °C and utilizes a molded plastic case with UL94V-0 flame retardant epoxy.
Feature Summary
- Glass passivated chip construction for high reliability
- Low reverse current and low forward voltage drop
- High surge current capability
- Suitable for printed circuit board mounting
Applications
- General purpose rectification in power supplies
- AC to DC conversion circuits
- Bridge rectifier configurations for electronic equipment
Procurement Notes
Verify the manufacturer marking on the component body matches EIC Semiconductor branding. Confirm the part number suffix corresponds to the 800 V rating. Ensure compliance with RoHS directives if lead-free assembly is required. Check datasheet revisions for updated thermal or electrical specifications before finalizing procurement orders.
Selection Notes
Select this component when an 800 V blocking voltage is required for 4 A applications. Consider the 120 A surge rating for inrush current handling. Verify ambient temperature derating curves if operating above 40 °C. Ensure PCB layout accommodates the KBL package dimensions and terminal spacing for proper heat dissipation.
Part Context
The KBL408 belongs to the KBL series of miniature single-phase bridge rectifiers manufactured by EIC Semiconductor. This series covers voltage ratings from 50 V to 1000 V, sharing identical mechanical footprints and thermal characteristics across variants. The KBL408 specifically addresses mid-range voltage requirements within this standardized product family.
Replacement Considerations
Cross-reference with other manufacturers' KBL408 parts ensuring identical 800 V PRV and 4 A IF(AV) ratings. Verify pinout compatibility and physical dimensions match the original design constraints.
