UCC23313BDWY

Overview

The UCC23313BDWY is a single-channel optically isolated gate driver designed for IGBTs, MOSFETs, and SiC MOSFETs. It provides 3.75-kVRMS isolation with an opto-compatible input interface. The device delivers a peak output current of 4.5 A source and 5.3 A sink. Operating voltage ranges from 15 V to 30 V. Key timing parameters include a maximum propagation delay of 105 ns, rise time of 28 ns, and fall time of 25 ns at VCC=15V. It operates within a temperature range of -40°C to +125°C in a SOIC-6 package.

Feature Summary

• Opto-compatible input design enables pin-to-pin drop-in replacement for traditional optocoupler-based gate drivers.
• Provides robust 3.75-kVRMS single-channel isolation suitable for high-voltage power conversion applications.
• Delivers strong drive capability with 4.5-A source and 5.3-A sink peak currents for fast switching.

Applications

• Gate driving for Insulated Gate Bipolar Transistors (IGBTs)
• Gate driving for Silicon Carbide (SiC) MOSFETs
• Gate driving for Silicon MOSFETs

Procurement Notes

Verify the specific suffix 'BDWY' corresponds to the tube packaging variant, as other suffixes like 'DWYR' indicate reel packaging. Confirm the manufacturer date code and lot traceability requirements against your manufacturing standards. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Cross-reference the ordering part number with the official Texas Instruments product selection guide to confirm availability status and lifecycle stage before finalizing procurement plans.

Selection Notes

Select this component when a direct replacement for legacy optocoupler gate drivers is required without redesigning the PCB footprint. Choose the UCC23313BDWY for applications needing 3.75-kVRMS isolation rather than higher ratings found in the UCC235xx series. Consider the SOIC-6 package constraints and thermal dissipation capabilities (750 mW) during layout planning. Verify that the 105 ns propagation delay meets the timing requirements of the target power stage.

Part Context

The UCC23313 belongs to Texas Instruments' family of opto-compatible isolated gate drivers. It bridges the gap between traditional discrete optocouplers and advanced capacitive isolation technologies by maintaining compatibility with existing optocoupler designs while offering improved performance metrics such as faster switching speeds and tighter parameter matching across channels.

Replacement Considerations

This device serves as a pin-to-pin, drop-in upgrade for many standard opto-isolated gate drivers. When substituting, ensure the original circuit supports the 15 V to 30 V supply range and verify that the 3.75-kVRMS isolation rating meets the system safety requirements.
