KBL410-G

Overview

The KBL410-G is a bridge rectifier diode manufactured by Comchip Technology, designed for general-purpose applications. It features a single-phase configuration with four elements housed in a KBL package. The device supports an average forward rectified current of 4A and withstands a maximum repetitive peak reverse voltage of 1000V. Key electrical parameters include a maximum non-repetitive peak forward surge current of 150A and a maximum DC reverse leakage current of 5μA at rated voltage. The component operates within a junction temperature range of -55°C to +150°C and utilizes silicon as the semiconductor material.

Feature Summary

• Utilizes silicon epitaxial planar chip technology for robust performance
• Provides polarity protection and free-wheeling capabilities in low-voltage circuits
• Features lead-free construction compliant with RoHS requirements

Applications

• Low voltage high frequency inverters
• Free wheeling diode circuits
• Polarity protection systems

Procurement Notes

Verify the specific manufacturer designation when sourcing, as the KBL410 part number is widely produced by multiple vendors including Goodwork and ASEMI. Confirm that the Comchip Technology variant matches the required KBL package dimensions and terminal solderability standards per MIL-STD-750 Method 2026. Ensure the ordering suffix aligns with the desired environmental compliance level.

Selection Notes

Select this component for designs requiring a 1000V blocking capability with a 4A continuous current rating. The DO-201AD or equivalent KBL form factor suits through-hole mounting constraints. Consider the 150A surge current rating for inductive load switching scenarios. Verify thermal management requirements given the 150°C maximum operating temperature limit.

Part Context

Comchip Technology specializes in discrete semiconductors, including Schottky barrier rectifiers and standard diodes. The KBL410-G belongs to their line of leaded bridge rectifiers, distinct from their SMD offerings like the SB series. This product line targets industrial and consumer electronics requiring reliable AC-to-DC conversion components.

Replacement Considerations

Direct substitutes include the KBL410 from other manufacturers such as Goodwork or ASEMI, provided the pinout and mechanical dimensions are identical. Verify that alternative sources meet the same 1000V/4A specifications and RoHS compliance before integration.
