B125C800G-E4/51

Bridge Rectifier Overview

The B125C800G-E4/51 is a glass-passivated single-phase bridge rectifier manufactured by Vishay Semiconductors. It provides an average forward output current of 0.9 A and supports maximum repetitive peak reverse voltages up to 200 V. The device features a WOG package with silver-plated leads for through-hole mounting. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.0 V at 0.9 A and a maximum reverse current of 10 μA. It withstands a non-repetitive peak forward surge current of 45 A and operates within a junction temperature range of -40 °C to +125 °C.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix /51 corresponds to the required bulk plastic bag packaging configuration. Confirm RoHS compliance status as indicated by the E4 designation. Ensure the selected component matches the exact voltage rating requirements for the target circuit design before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component when a 200 V peak reverse voltage rating is required alongside a 0.9 A continuous current capacity. The WOG package offers a compact footprint suitable for space-constrained PCB layouts. Verify thermal derating curves are considered if ambient temperatures exceed standard operating conditions or if capacitive loads are present.

Bridge Rectifier Part Context

This part belongs to the Vishay BxxxC800G series of glass-passivated bridge rectifiers. The series includes variants with different voltage ratings such as B40C, B80C, B250C, and B380C. All members share identical physical dimensions, current ratings, and thermal characteristics, differing only in their maximum repetitive peak reverse voltage capabilities.

Bridge Rectifier Replacement Considerations

Compatible substitutes within the same family include B40C800G-E4/51, B80C800G-E4/51, B250C800G-E4/51, and B380C800G-E4/51. These parts maintain identical mechanical and thermal profiles but offer different voltage ratings. Ensure the replacement voltage rating meets or exceeds the original circuit requirements.
