UC3611DW

Diode Arrays Overview

The UC3611DW is a quad Schottky diode array manufactured by Texas Instruments, designed for surface-mount applications. It features four independent Schottky barrier rectifiers housed in a SOIC-16 package. The device supports a maximum repetitive reverse voltage of 50 V and an average forward current of 3 A per diode. Key electrical characteristics include a typical forward voltage of 900 mV at rated current and a low reverse leakage current of 10 uA. Operating temperatures range from 0°C to +70°C.

Diode Arrays Feature Summary

• Integrates four independent Schottky diodes into a single compact surface-mount package.
• Utilizes Schottky technology to achieve low forward voltage drop and fast switching speeds.
• Provides high surge current handling capability suitable for power supply input stages.

Diode Arrays Applications

• DC-DC converter input rectification
• Free-wheeling diodes in synchronous rectifier circuits
• Power supply protection against reverse polarity

Diode Arrays Procurement Notes

Verify the specific suffix (e.g., DW) to confirm the SOIC-16 package type and tube packaging. Confirm RoHS compliance status with the manufacturer or authorized distributor prior to ordering. Ensure the design accounts for the thermal dissipation requirements associated with the 3 A rating in the selected enclosure.

Diode Arrays Selection Notes

Select this component when a quad configuration is required to save board space compared to discrete diodes. The SOIC-16 package offers a balance between current capacity and footprint size. Consider the 50 V voltage rating to ensure adequate headroom for the target application's peak inverse voltage conditions.

Diode Arrays Part Context

This part belongs to the UC3611 series of Schottky diode arrays. It serves as a surface-mount alternative to through-hole variants like the UC3611N. The device is commonly used in industrial and consumer electronics where efficient power conversion and compact layout are priorities.

Diode Arrays Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify that any replacement maintains the 50 V reverse voltage and 3 A current ratings. Ensure the replacement package matches the SOIC-16 form factor for PCB compatibility.
