DF1502S-E3/77

Bridge Rectifier Overview

The DF1502S-E3/77 is a miniature glass-passivated single-phase surface-mount bridge rectifier manufactured by Vishay General Semiconductor. It provides a maximum repetitive peak reverse voltage (VRRM) of 200 V and supports a maximum average forward output rectified current (IF(AV)) of 1.5 A at an ambient temperature of 40 °C. The device features a peak forward surge current rating (IFSM) of 50 A, a maximum instantaneous forward voltage drop (VF) of 1.1 V at 1.5 A, and a maximum DC reverse current (IR) of 5 μA at rated blocking voltage. Operating junction and storage temperatures range from -55 °C to +150 °C.

Bridge Rectifier Feature Summary

• Glass passivation ensures stable electrical characteristics and reliable performance under varying thermal conditions.
• DFS package design facilitates automated placement for efficient printed circuit board assembly.
• High surge current capability allows the component to withstand transient load spikes during operation.

Bridge Rectifier Applications

• AC/DC bridge full wave rectification in switch-mode power supplies
• Lighting ballast circuits
• Battery charger systems

Bridge Rectifier Procurement Notes

Verify that the ordering suffix /77 corresponds to the 13-inch diameter paper tape and reel delivery mode with a base quantity of 1500 units. Confirm RoHS compliance via the E3 suffix designation. Ensure procurement channels provide original manufacturer documentation to validate authenticity and traceability before integration into production lines.

Bridge Rectifier Selection Notes

Select this component when a 200 V reverse voltage rating and 1.5 A continuous current capacity are required within a compact DFS footprint. Evaluate thermal resistance parameters against the specific PCB copper pad layout to ensure junction temperatures remain within the specified operating range during high-load scenarios.

Bridge Rectifier Part Context

This part belongs to the DF15xxS series of miniature surface-mount bridge rectifiers. The series encompasses multiple voltage ratings ranging from 50 V to 1000 V, sharing identical mechanical dimensions and electrical characteristics except for the reverse voltage specifications. This standardization simplifies inventory management across different product designs.

Bridge Rectifier Replacement Considerations

Direct substitutes include other Vishay parts within the same DFS package family, such as the DF1501S or DF1504S, provided their respective voltage ratings align with the circuit requirements. Cross-manufacturer replacements must match the 1.5 A current rating, 200 V blocking voltage, and DFS pinout configuration.
