SI823H5CD-IS3

Isolators - Gate Drivers Overview

The SI823H5CD-IS3 is a dual isolated gate driver from the Si823Hx series, manufactured by Skyworks Solutions Inc. It features silicon-based digital isolation technology with a 5 kV RMS isolation rating and operates within an extended temperature range of -40°C to +125°C. The device is housed in a wide-body SOIC-14 (SOIC-W) surface-mount package and holds AEC-Q100 qualification for automotive applications. It provides two non-inverting channels with integrated undervoltage lockout (UVLO) functionality.

Isolators - Gate Drivers Feature Summary

• Utilizes proprietary silicon dioxide (SiO2) digital isolation technology for high reliability and immunity to electromagnetic interference.
• Provides robust galvanic isolation between control and power sides with a 5 kV RMS working voltage rating.
• Integrates undervoltage lockout (UVLO) circuits on both input and output sections to ensure safe switching operations.
• Supports high-speed signal transmission with low propagation delay characteristics suitable for modern power electronics.

Isolators - Gate Drivers Applications

• Automotive electric vehicle (EV) and hybrid electric vehicle (HEV) motor drives
• Industrial inverters and AC/DC motor control systems
• High-voltage DC-to-DC converter topologies
• Solar microinverter and grid-tied inverter designs

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS3' corresponds to the tape-and-reel packaging variant rather than tube packaging when ordering. Confirm that the wide-body SOIC-14 footprint matches your PCB layout requirements. Ensure compliance with RoHS directives and check for any regional distribution restrictions or moisture sensitivity levels prior to procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a 5 kV isolation barrier is required for dual-channel gate driving in harsh environments. The AEC-Q100 qualification makes it suitable for automotive standards. Compare against lower isolation ratings if system voltage permits, or consider single-channel variants if only one switch needs driving. Verify thermal management capabilities for the SOIC-W package under high-frequency switching conditions.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx family of isolated gate drivers designed for high-voltage industrial and automotive applications. It complements other members like the SI823H9CC-IS (single channel) and SI8239x series (lower isolation). The family emphasizes digital isolation advantages over traditional magnetic transformers, offering better size efficiency and consistency.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other Skyworks Si823Hx dual-channel variants such as SI823H6CD-IS3. Cross-brand replacements require matching the 5 kV isolation rating, SOIC-W-14 package, and UVLO features. Always verify pin compatibility and electrical parameters before substituting.
