DFL1510S-E3/77

Bridge Rectifier Overview

The DFL1510S-E3/77 is a low-profile miniature glass-passivated single-phase surface mount bridge rectifier manufactured by Vishay General Semiconductor. It provides a maximum average forward output rectified current of 1.5 A at an ambient temperature of 40 °C and supports a maximum repetitive peak reverse voltage of 1000 V. The device features a peak forward surge current capability of 50 A and a typical instantaneous forward voltage drop of 1.1 V at the rated current. Operating junction temperatures range from -55 °C to +150 °C, with a maximum DC reverse leakage current of 5 µA at 25 °C. The component utilizes a DFS low profile package with matte tin-plated leads.

Bridge Rectifier Feature Summary

• Low profile design with a typical height of 2.5 mm for compact board layouts
• Glass passivated chip junction for enhanced reliability and stability
• High surge current capability suitable for demanding power applications
• Meets MSL level 1 per J-STD-020 standards for moisture sensitivity

Bridge Rectifier Applications

• AC/DC bridge full wave rectification in switch mode power supplies (SMPS)
• Lighting ballast circuits
• Battery chargers and adapters
• Home appliances and office equipment
• Telecommunication applications

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix to confirm the delivery mode, as the /77 suffix indicates tape and reel packaging while other suffixes may denote tubes. Confirm RoHS compliance status through the E3 designation and ensure the component meets the required flammability rating of UL 94 V-0 for the molding compound before finalizing procurement specifications.

Bridge Rectifier Selection Notes

Select this component when a low-profile surface mount bridge rectifier is required for high-voltage applications up to 1000 V. Ensure the PCB layout accommodates the DFS package dimensions and that the thermal management strategy accounts for the specified thermal resistance values. Validate that the operating environment stays within the -55 °C to +150 °C junction temperature range for optimal performance.

Bridge Rectifier Part Context

This part belongs to the DFL15xxS series of low-profile miniature glass-passivated single-phase surface mount bridge rectifiers. The series includes variants with different reverse voltage ratings ranging from 50 V to 1000 V, all sharing the same 1.5 A current rating and DFS package style. The DFL1510S specifically denotes the 1000 V variant within this family.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same series include DFL1508S-E3/77 for 800 V applications. Cross-manufacturer replacements must match the 1.5 A current rating, 1000 V reverse voltage, DFS package footprint, and low-profile height constraints to ensure mechanical compatibility.
