B80FS

Bridge Rectifier Overview

The B80FS is a fast recovery surface-mount bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current rating of 1 A and a peak repetitive reverse voltage of 800 V. The device utilizes a 4-SO-DIL SLIM package for compact circuit board integration. Key electrical characteristics 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. The component operates within a junction temperature range of -50°C to +150°C.

Bridge Rectifier Feature Summary

• Fast recovery performance with a typical reverse recovery time of 300 ns
• High thermal stability supporting operation up to 150°C junction temperature
• Compact SMD packaging designed for space-constrained applications

Bridge Rectifier Applications

• General-purpose AC-DC power supply circuits
• Industrial electronics requiring high-voltage rectification
• White goods control boards
• Battery charger input stages

Bridge Rectifier Procurement Notes

Verify the specific datasheet revision before finalizing designs, as Diotec reserves the right to modify product information without notice. Confirm that the selected protective resistance and load capacitor values align with the manufacturer's guidelines to ensure the surge current limits are not exceeded during operation.

Bridge Rectifier Selection Notes

Select this component when a single-phase bridge rectifier with fast switching capabilities is required for 800 V applications. Ensure the design accommodates the recommended protective resistance (Rt) of 4.0 Ohms to manage the non-repetitive peak forward surge current effectively under standard operating conditions.

Bridge Rectifier Part Context

The B80FS belongs to the BxxFS series of fast recovery SMD bridge rectifiers from Diotec Semiconductor. This family includes variants such as the B40FS, B125FS, and B380FS, which share similar physical dimensions and thermal characteristics but differ in their voltage ratings and associated protective resistance requirements.

Bridge Rectifier Replacement Considerations

Cross-reference with other manufacturers offering SO-DIL-4 fast recovery bridge rectifiers rated at 800 V and 1 A. Verify that substitute components meet or exceed the 300 ns reverse recovery time and 1.3 V forward voltage specifications to maintain circuit performance.
