UES703

Single Diodes Overview

The UES703 is a general-purpose rectifier diode manufactured by Microchip Technology. It features a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current rating of 25 A. The device utilizes a DO-203AA (DO-204AC) axial leaded package, suitable for through-hole mounting applications. Key electrical characteristics include a maximum DC reverse leakage current of 25 µA at rated voltage and a typical forward voltage drop of 975 mV at the rated current level. The component is designed to operate with a junction temperature range up to 175°C, ensuring reliability in high-temperature environments.

Single Diodes Feature Summary

• High thermal stability with a maximum junction temperature rating of 175°C
• Robust current handling capability with a 25 A average forward rectified current rating
• Standard axial leaded packaging for reliable through-hole integration

Single Diodes Applications

• General-purpose power supply rectification
• Battery charging circuits
• DC power distribution systems

Single Diodes Procurement Notes

Verify the specific suffix or variant code when ordering, as Microchip may offer different voltage or current ratings within the UES series. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as legacy components may have varying environmental declarations. Ensure the selected package matches the required PCB footprint and mounting style for your design.

Single Diodes Selection Notes

Select this component when a standard axial rectifier with 150 V blocking voltage and 25 A continuous current capacity is required. Consider the thermal management requirements due to the power dissipation associated with high-current operation. Verify that the DO-203AA package dimensions fit the mechanical constraints of the enclosure and PCB layout.

Single Diodes Part Context

The UES703 belongs to Microchip's lineup of general-purpose rectifier diodes, often grouped with similar devices like the UES801 and BYW series. These components are typically used in industrial and consumer electronics where robust, cost-effective rectification is needed. The DO-203AA package is a standard form factor widely supported in existing hardware designs.

Single Diodes Replacement Considerations

Direct substitutes may include other 150 V, 25 A axial rectifiers from manufacturers such as Vishay or STMicroelectronics, provided they match the pinout and thermal characteristics. Cross-referencing part numbers like UES703R or compatible BYW variants may be necessary depending on specific performance tolerances.
