DF1501S

Bridge Rectifier Overview

The DF1501S is a single-phase, surface-mount standard recovery bridge rectifier manufactured by Diodes Incorporated. It features glass passivated die construction and operates with an average forward rectified current of 1.5 A at +40°C. The device has a peak repetitive reverse voltage rating of 100 V and a maximum forward voltage drop of 1.1 V at the rated current. It supports a non-repetitive peak forward surge current of 50 A for 8.3 ms half-sine waves. The component is housed in a DF-S molded plastic package with tin-plated leads, suitable for automated placement.

Bridge Rectifier Feature Summary

• Glass passivated die construction ensures stable electrical performance.
• Low forward voltage drop combined with high current capability.
• Designed specifically for surface-mount applications to facilitate automated assembly.

Bridge Rectifier Applications

• General-purpose AC to DC conversion in power supply circuits
• Bridge rectification in consumer electronics devices
• Standard recovery applications requiring compact surface-mount solutions

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number DF1501S typically indicates tube packaging containing 50 units per carrier. Alternative suffixes such as -T denote tape and reel packaging with 1500 units. Confirm the required packing quantity matches the production needs before placing orders to ensure compatibility with manufacturing equipment.

Bridge Rectifier Selection Notes

Select this component for designs requiring a 100 V reverse voltage rating and 1.5 A continuous current capacity in a small footprint. Ensure the application environment stays within the -55°C to +150°C junction temperature range. Derate the forward current by 20% if the load is capacitive to maintain reliability and prevent thermal overstress during operation.

Bridge Rectifier Part Context

This component belongs to the DF15005S through DF1510S series of miniature glass passivated bridge rectifiers. The series offers various reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 1.5 A forward current capability. All variants share the same DF-S surface-mount package and mechanical dimensions, allowing for flexible design choices based on voltage requirements.

Bridge Rectifier Replacement Considerations

Direct functional substitutes include other 1.5 A, 100 V surface-mount bridge rectifiers in compatible packages. Verify that any replacement maintains the same or higher peak reverse voltage, forward current, and forward voltage specifications. Ensure the alternative component meets the same moisture sensitivity level and flammability classification standards.
