DF1504S-T

Bridge Rectifier Overview

The DF1504S-T is a single-phase standard recovery bridge rectifier manufactured by Diodes Incorporated. It features a glass passivated die construction and is housed in the surface-mount DF-S package. The device supports an average forward rectified current of 1.5 A at +40°C ambient temperature and withstands a peak repetitive reverse voltage of 400 V. Electrical characteristics include a maximum forward voltage drop of 1.1 V at 1.5 A and a peak reverse current of 10 µA at rated DC blocking voltage. It offers a non-repetitive peak forward surge current rating of 50 A for 8.3 ms half-sine waves.

Bridge Rectifier Feature Summary

• Glass passivated die construction ensures stable operation and low leakage current.
• Designed specifically for automated surface-mount assembly processes.
• Capable of handling high surge overload conditions up to 50 A peak.

Bridge Rectifier Applications

• General-purpose AC-to-DC power supply circuits
• Battery charging systems
• Adapters and converters

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix to confirm tape and reel packaging quantities. Confirm RoHS compliance status and lead-free finish requirements against project specifications. Ensure the selected component matches the required voltage and current ratings for the target application environment.

Bridge Rectifier Selection Notes

Select this component when a 400 V reverse voltage rating is required for surface-mount designs. Verify thermal management needs, as the junction-to-ambient thermal resistance is 40 °C/W. Consider derating the forward current if operating above +40°C ambient temperature or with capacitive loads.

Bridge Rectifier Part Context

This part belongs to the DF15xxxS-T series, which covers reverse voltages from 50 V to 1000 V. All variants share identical mechanical dimensions, forward current capabilities, and package types, differing only in their peak repetitive reverse voltage ratings.

Bridge Rectifier Replacement Considerations

Direct replacements within the same series include DF1502S-T (200 V) and DF1506S-T (600 V), provided the voltage rating aligns with circuit requirements. Cross-manufacturer equivalents must match the 1.5 A current, 400 V voltage, and DF-S package constraints.

Bridge Rectifier FAQ

What is the maximum non-repetitive peak forward surge current?

The device can withstand a non-repetitive peak forward surge current of 50 A for an 8.3 ms single half-sine wave superimposed on rated load.

How does the forward current change with temperature?

The average forward rectified current is rated at 1.5 A at +40°C ambient temperature. Derating is required for higher temperatures or capacitive loads.

Is the component suitable for high-frequency applications?

It is a standard recovery bridge rectifier. The typical total capacitance per element is 25 pF, measured at 1.0 MHz.
