KBU1008-G

Overview

The KBU1008-G is a single-phase bridge rectifier manufactured by Comchip Technology. It features a silicon technology construction with a maximum repetitive peak reverse voltage of 800V and an average forward rectified current of 10A. The device utilizes a molded plastic technique for reliable, low-cost construction. Key electrical specifications include a maximum instantaneous forward voltage of 1V at rated current and a peak forward surge current rating of 240A for an 8.3ms half-sine wave. The component supports through-hole mounting and operates within a specified temperature range.

Feature Summary

• Surge overload rating of 240 amperes peak
• Ideal for printed circuit board applications
• Reliable low cost construction utilizing molded plastic technique

Applications

• General purpose rectification in power supplies
• AC to DC conversion circuits
• Industrial control systems requiring robust bridge rectification

Procurement Notes

Verify the specific ordering suffix matches the required voltage and current ratings. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the through-hole package dimensions align with the target PCB footprint. Cross-reference the manufacturer's latest datasheet for any updates to thermal characteristics or mechanical tolerances before finalizing procurement.

Selection Notes

Select this component when an 800V reverse voltage rating and 10A continuous current capacity are required. The 240A surge capability provides protection against transient load spikes. Consider the through-hole mounting style for applications requiring higher mechanical stability compared to surface-mount alternatives. Evaluate thermal management requirements based on the 1V forward voltage drop under load conditions.

Part Context

This part belongs to Comchip Technology's single-phase bridge rectifier lineup. It is designed for general-purpose power conversion tasks. The molded plastic construction distinguishes it from older ceramic or metal-housed variants. It serves as a standard solution for medium-power AC-DC applications where reliability and cost-effectiveness are prioritized over miniaturization.

Replacement Considerations

Direct substitutes must match the 800V VR, 10A IF, and KBU package outline. Verify pinout compatibility and thermal resistance values. Generic replacements should offer equal or superior surge current ratings. Consult manufacturer cross-reference lists for validated equivalent parts.
