The DF1508S-E3/77 is a miniature glass-passivated single-phase surface-mount bridge rectifier from Vishay. It is designed for AC/DC full-wave rectification in switched-mode power supplies, lighting ballasts, adapters, battery chargers, home appliances, office equipment, and telecommunications equipment. The device is rated for a maximum repetitive peak reverse voltage of 800 V and a maximum average forward output current of 1.5 A at 40 °C when mounted on a PCB with 13 mm x 13 mm copper pads.
Key electrical characteristics include a peak forward surge current of 50 A, a maximum forward voltage of 1.1 V at 1.5 A, a maximum reverse leakage current of 5 µA at 25 °C and 500 µA at 125 °C, and a typical junction capacitance of 25 pF. The operating junction and storage temperature range is -55 °C to +150 °C. Thermal resistance is 40 °C/W junction-to-ambient and 15 °C/W junction-to-lead.
The bridge rectifier uses a 4-SMD gull-wing package with supplier device package designation DFS. It is intended for automated surface-mount assembly. The molding compound meets UL 94 V-0 flammability rating, and the matte tin plated terminals are solderable per J-STD-002 and JESD22-B102. The E3 suffix indicates a RoHS-compliant, commercial-grade, lead-free part.
