SI823H8CB-IS1R

Isolators - Gate Drivers Overview

The SI823H8CB-IS1R is a dual isolated gate driver from Skyworks Solutions, featuring a 2.5 kVrms isolation rating and automotive AEC-Q100 qualification. It utilizes silicon-isolation technology in an SOIC-16 package with a tape-and-reel configuration. The device operates within a supply voltage range of 3 V to 5.5 V and supports temperatures from -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 30 ns, rise and fall times of 12 ns each, and a continuous output current capability of 4 A per channel.

Isolators - Gate Drivers Procurement Notes

Verify that the suffix 'IS1R' corresponds to the specific SOIC-16 tube-to-reel conversion or variant requirements for your assembly line. Confirm the 2.5 kV isolation rating aligns with system safety standards. Ensure moisture sensitivity handling protocols are followed during surface-mount placement. Cross-reference the datasheet revision date against your design timeline to validate parameter consistency.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel driver with 2.5 kV isolation is required for automotive applications. Compare against the SI823H8CD series if higher 5 kV isolation is needed. Consider the 4 A peak current limit for load matching. Evaluate the SOIC-16 footprint against available PCB space constraints relative to smaller DFN packages.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx family of isolated gate drivers designed for robust performance in noisy environments. The series leverages proprietary silicon dioxide insulation to replace traditional magnetic transformers. This specific model targets high-volume automotive manufacturing due to its standardized packaging and qualified reliability profile.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other variants within the Si823Hx family such as the SI823H8BD or SI823H8CD, provided the isolation voltage and pinout compatibility match the existing design requirements.
