SI823H3CB-IS1R

Isolators - Gate Drivers Overview

The SI823H3CB-IS1R is a current-isolated gate driver from the Si823Hx series, manufactured by Skyworks Solutions. It features a narrow-body SOIC-16 package and provides dual channel isolation for high-side and low-side MOSFET or IGBT control. The device utilizes silicon dioxide (SiO2) technology to achieve galvanic isolation with a working voltage of 2500 Vrms. It operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature range from -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between input logic and output power stages using silicon dioxide dielectric technology.
• Integrates dual channels suitable for half-bridge configurations with independent high-side and low-side drive outputs.
• Features robust transient immunity and common-mode rejection capabilities inherent to capacitive isolation architecture.

Isolators - Gate Drivers Applications

• Industrial motor drives requiring isolated gate control
• Inverter circuits in renewable energy systems
• Switched-mode power supplies with high-voltage isolation requirements

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R against official Skyworks documentation to confirm the reel packaging configuration and pinout orientation. Ensure the order matches the exact part number including all alphanumeric characters to avoid receiving variants with different isolation ratings or package types. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance status and recommended soldering profiles prior to procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver is required in a narrow-body SOIC-16 footprint. The Si823H3 variant offers a specific isolation rating distinct from other members of the Si823Hx family. Consider the thermal performance of the narrow-body package and ensure the PCB layout accommodates the creepage and clearance distances mandated by the 2500 Vrms working voltage specification for safety compliance.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx family of current-isolated gate drivers from Skyworks Solutions. The family includes single and dual channel options in various packages such as SOIC-8, SOIC-14, and SOIC-16. These devices are designed to replace traditional transformer-based isolation solutions, offering higher reliability and smaller form factors for modern power electronics applications.

Isolators - Gate Drivers Replacement Considerations

Direct replacements within the same family include SI823H3CB-IS1. Verify that substitute parts maintain the identical narrow-body SOIC-16 package and the 2500 Vrms isolation rating. Check for differences in propagation delay and peak output current specifications if driving high-capacitance loads.
