B125FS

Bridge Rectifier Overview

The B125FS is a fast recovery surface-mount bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current rating of 1 A and a repetitive peak reverse voltage of 125 V. The device utilizes a SO-DIL-4 package for compact circuit integration. Key electrical parameters include a maximum forward voltage of 1.3 V at 1 A, a leakage current below 5 µA at rated voltage, and a typical reverse recovery time of 300 ns. It supports a non-repetitive peak forward surge current of 40 A under standard conditions and operates within a junction temperature range of -50°C to +150°C.

Bridge Rectifier Feature Summary

• Fast recovery characteristics with a typical reverse recovery time of 300 ns
• High thermal stability supporting operation up to a junction temperature of +150°C
• Robust surge handling capability with a peak forward surge current rating of 40 A

Bridge Rectifier Applications

• General purpose AC/DC conversion in power supplies
• Battery charging circuits requiring fast switching
• Industrial control systems operating in high-temperature environments

Bridge Rectifier Procurement Notes

Verify the specific datasheet version directly from Diotec Semiconductor before finalizing designs. Confirm that the SO-DIL-4 footprint matches your PCB layout requirements. Ensure that the selected protective resistance and load capacitor values comply with the manufacturer's guidelines to prevent exceeding the peak surge current limits during operation.

Bridge Rectifier Selection Notes

Select this component when a 1 A single-phase bridge rectifier with fast recovery properties is required. Verify that the 125 V reverse voltage rating exceeds the peak inverse voltage present in the application circuit. Consider the thermal resistance specifications if the ambient temperature approaches the upper operational limit or if derating is necessary for sustained high-current loads.

Bridge Rectifier Part Context

The B125FS belongs to the B40FS through B380FS series of fast recovery SMD bridge rectifiers. This family shares common packaging and general performance traits while varying in voltage ratings. The series is designed for applications demanding efficient rectification in compact surface-mount configurations without sacrificing switching speed.

Bridge Rectifier Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the 1 A current rating, 125 V minimum reverse voltage, and compatible SO-DIL-4 package dimensions.
