UCC23513BDWY

Overview

The UCC23513BDWY is a single-channel optically compatible isolated gate driver from Texas Instruments, designed for driving IGBTs, MOSFETs, and SiC MOSFETs. It features a 5.7 kVRMS reinforced isolation rating and operates within a supply voltage range of 14 V to 33 V. The device delivers a peak source current of 4.5 A and a peak sink current of 5.3 A. Key electrical parameters include a maximum propagation delay of 105 ns, a minimum common-mode transient immunity (CMTI) of 150 kV/µs, and a maximum pulse width distortion of 35 ns. It is housed in an extended SO-6 package with creepage and clearance distances exceeding 8.5 mm.

Feature Summary

• Opto-compatible input architecture using an enhanced diode (e-diode) for superior reliability and aging resistance compared to traditional LEDs.
• High common-mode transient immunity (CMTI) of 150 kV/µs minimizes false triggering in noisy environments.
• Extended SO-6 package provides creepage and clearance distances greater than 8.5 mm for enhanced safety isolation.
• Pin-to-pin compatibility allows direct replacement of standard optocoupler-based gate drivers without schematic or layout changes.

Applications

• Motor drives
• Solar inverters
• Industrial power supplies

Procurement Notes

Verify the specific suffix 'DWY' to confirm the tube packaging format, as the 'R' variant indicates tape-and-reel. Confirm the lead status, as some sources indicate potential end-of-life or obsolescence warnings for this specific part number. Ensure compliance with RoHS directives and check humidity sensitivity levels prior to storage and reflow processes.

Selection Notes

Select the UCC23513BDWY when replacing legacy optocoupler drivers to achieve higher CMTI and lower propagation delay. The 33 V supply capability supports dual-rail configurations required for IGBT and SiC MOSFET applications. The extended SO-6 package is suitable for designs requiring high isolation creepage distances. Ensure the input logic levels are compatible with the e-diode input structure.

Part Context

This component belongs to the UCC23513 family of isolated gate drivers. It serves as a high-performance alternative to conventional optocouplers, offering improved signal integrity and longevity. The device is engineered for robust operation in harsh industrial environments, providing enhanced isolation protection while maintaining compact form factors through its surface-mount SOIC-6 package.

Replacement Considerations

The UCC23513 series is designed as a pin-to-pin replacement for many standard optocoupler-based gate drivers. Verify that the existing design can accommodate the slightly different input characteristics of the e-diode structure. Ensure thermal management aligns with the 750 mW power dissipation rating in the SOIC-6 package.
