DF15005S-E3/77

Bridge Rectifier Overview

The DF15005S-E3/77 is a miniature glass passivated single-phase surface-mount bridge rectifier manufactured by Vishay General Semiconductor. It belongs to the DFS series and provides an average forward output rectified current of 1.5 A at an ambient temperature of 40 °C. The maximum repetitive peak reverse voltage (VRRM) is rated at 50 V, with a corresponding maximum RMS voltage of 35 V and maximum DC blocking voltage of 50 V. Peak forward surge current capability reaches 50 A for half-sine waves under rated load conditions. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V at 1.5 A and a maximum DC reverse current of 5 μA at rated voltage and 25 °C. The device operates within a junction and storage temperature range of -55 °C to +150 °C.

Bridge Rectifier Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes match project requirements. Validate datasheet revision dates against manufacturing lot codes to ensure technical specifications remain current. Request material categorization documentation if environmental compliance standards are mandatory for the intended deployment.

Bridge Rectifier Selection Notes

Select this component when a low-voltage (50 V) surface-mount bridge rectifier is required for compact designs. Ensure thermal management strategies account for the specified thermal resistance values. Verify that the 1.5 A continuous current rating aligns with the application's steady-state load requirements. Consider the DFS package dimensions for footprint compatibility during PCB layout planning.

Bridge Rectifier Part Context

This part is part of the Vishay DF15xxS family of miniature bridge rectifiers. Variants within the series share identical mechanical and thermal characteristics but differ in reverse voltage ratings, such as the DF1501S (100 V), DF1502S (200 V), and DF1504S (400 V). All members utilize the same DFS case style and support similar operating temperatures and current capabilities.

Bridge Rectifier Replacement Considerations

Direct substitutes within the Vishay lineup include other DFS-series bridge rectifiers with matching current ratings but different voltage thresholds. Cross-manufacturer replacements must verify equivalent DFS package dimensions, thermal resistance profiles, and forward voltage characteristics to maintain circuit performance integrity.
