KBU6D-M3/P

Overview

The KBU6D-M3/P is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes glass-passivated silicon junctions for reliable operation. The device supports a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 6 A. It features a high surge current capability to withstand transient loads. The component is designed for through-hole mounting in the KBPM package, ensuring robust mechanical stability. It operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Glass passivation provides protection against mechanical stresses and ensures long-term reliability under harsh conditions.
• High surge current capability allows the device to handle temporary overloads without failure.
• Designed for efficient AC-to-DC full-wave rectification in switching power supply applications.

Applications

• General purpose use in AC-to-DC bridge full-wave rectification
• Switching power supplies

Procurement Notes

Verify the specific suffix PBF or M3 against the manufacturer's datasheet to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the required package style and electrical ratings. Cross-reference with official Vishay documentation to validate availability and current production status before procurement.

Selection Notes

Select this component when a 6 A bridge rectifier with 600 V reverse voltage rating is required. Consider the KBPM package dimensions for PCB layout constraints. Verify that the operating environment stays within the specified -55°C to +175°C junction temperature range. Ensure the circuit design accounts for the device's thermal dissipation characteristics.

Part Context

This part belongs to the KBP series of glass-passivated single-phase bridge rectifiers from Vishay. These components are widely used in general-purpose rectification tasks. The series offers various voltage ratings and current capacities to suit different power supply designs. The KBU6D variant specifically targets higher current applications compared to lower-rated siblings.

Replacement Considerations

Check for direct substitutes such as other 6 A, 600 V bridge rectifiers in the KBPM package. Ensure any replacement maintains identical pinout configuration and thermal performance. Verify that alternative parts meet the same UL recognition and safety standards if required by the application.
