Overview
The MDD KBL410 is a through-hole silicon bridge rectifier from the KBL series, featuring a molded plastic body and four solder-plated terminals. It provides a maximum repetitive peak reverse voltage of 1000V and an average forward output rectified current of 4.0A at a case temperature of 50°C. The device supports a peak forward surge current of 125A for an 8.3ms single half-sine wave. Electrical characteristics include a maximum forward voltage drop of 1.0V at 4.0A and a DC reverse current of 10µA at 25°C. The component operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- High forward surge current capability
- Low reverse leakage current
- Guaranteed high-temperature soldering resistance up to 260°C
- Plastic package with Underwrite Laboratory Flammability Classification 94V-0
Applications
- Printed circuit board mounting
- General purpose rectification in power supplies
- AC to DC conversion circuits
Procurement Notes
Verify the original part number matches MDD KBL410 and confirm the specification sheet revision A1 aligns with requirements. Ensure the package code indicates bulk packaging containing 500 pieces per box. Confirm RoHS and RoHS III compliance status before procurement. Validate that the terminal polarity marking on the body matches the intended circuit design.
Selection Notes
Select this component when a 1000V reverse voltage rating and 4A continuous current are required. Consider the 125A surge current capacity for applications with initial inrush currents. Verify thermal management needs against the 20°C/W thermal resistance rating. Ensure the operating environment stays within the specified -65°C to +150°C junction temperature limits.
Part Context
The KBL410 belongs to the KBL series of through-hole silicon bridge rectifiers manufactured by Microdiode Electronics (MDD). This series utilizes a molded plastic body designed for printed circuit board integration. The component is part of a broader lineup offering various voltage and current ratings within the same physical footprint.
Replacement Considerations
Cross-reference part numbers such as KBL4100000L40A may be used if electrical parameters match exactly. Verify terminal spacing and physical dimensions to ensure compatibility with existing PCB layouts. Confirm equivalent surge current and thermal resistance ratings before substitution.
