B125C5000A

Bridge Rectifier Overview

The Diotec Semiconductor B125C5000A is a single-phase diode bridge rectifier designed for commercial and industrial applications. It features an average forward current (IFAV) of 5.0 A and supports peak repetitive reverse voltages up to 1200 V. The device exhibits a maximum forward voltage drop of less than 1.0 V at 5 A and maintains leakage currents below 5 µA at rated voltage. Peak forward surge current reaches 165 A at 60 Hz, with a junction temperature range spanning from -50°C to +150°C.

Bridge Rectifier Feature Summary

• Full isolated case outline ensures sufficient clearance and creepage distances
• High admissible repetitive reverse voltage capability for robust performance
• Supports high forward surge currents suitable for demanding power stages

Bridge Rectifier Applications

• Industrial power supplies
• Input stage of frequency inverters
• Commercial applications requiring standard reliability

Bridge Rectifier Procurement Notes

Verify the specific article number suffix against official documentation, as variants like B125C5000-3000A and B125C5000-3300A designate identical devices under the common part number B125C5000A. Confirm RoHS compliance and Pb-free status through the manufacturer's latest datasheet or product change notices before finalizing procurement specifications.

Bridge Rectifier Selection Notes

Select this component when a 5 A continuous current rating and high voltage isolation are required in a compact form factor. Ensure the thermal resistance to ambient (20 K/W) aligns with the system's cooling strategy. Verify that the recommended protective resistance and load capacitor values match the circuit requirements to prevent exceeding the peak surge current limits during startup.

Bridge Rectifier Part Context

This component belongs to the BxxC5000 series of single-phase bridge rectifiers manufactured by Diotec Semiconductor. The series offers various voltage ratings from 40 V to 500 V, all sharing similar physical dimensions and mounting characteristics. The B125 variant specifically addresses higher voltage requirements within this standardized package family.

Bridge Rectifier Replacement Considerations

Check for equivalent single-phase bridge rectifiers with matching IFAV and VRRM ratings. Ensure replacement parts support the same TO-220AB or similar isolated case style if space constraints apply. Verify that the new component meets the required thermal resistance and surge current capabilities.
