SI82F39ABC-IS1R

Isolators - Gate Drivers Overview

The SI82F39ABC-IS1R is a dual-channel isolated gate driver from Skyworks Solutions, designed for high-voltage power switching applications. It features capacitive coupling technology providing 3750 Vrms isolation voltage and meets UL Recognized Standard SELVCD requirements. The device operates with a supply voltage range of 5 V to 30 V on the output side and supports input voltages from 3 V to 20 V. Key electrical parameters include a maximum propagation delay of 8 ns, rise time of 16 ns, and fall time of 19 ns. It delivers an output current of 2.5 A and functions within a temperature range of -40°C to +125°C. The component is housed in a 16-pin SOIC package.

Isolators - Gate Drivers Feature Summary

• Utilizes silicon dioxide (SiO2) capacitive coupling for robust signal isolation without magnetic interference.
• Provides enhanced safety insulation compliant with SELVCD standards for regulatory approval.
• Integrates a shutdown pin for precise control over driver state and system safety.
• Supports non-inverting logic configuration for straightforward interface with control signals.

Isolators - Gate Drivers Applications

• Isolated gate driving for IGBTs and MOSFETs in motor drives
• Power supplies requiring reinforced isolation barriers
• Industrial inverters and converters
• Solar microinverters and string inverters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R against the manufacturer's latest datasheet to confirm packaging type and tape-and-reel specifications. Ensure the order quantity aligns with standard reel sizes if applicable. Cross-reference the RoHS compliance status and lead times directly with authorized distributors or Skyworks sales representatives prior to finalizing procurement decisions.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation with high common-mode transient immunity is required. The 2.5 A peak drive current suits medium-power switching devices. Consider the 16-SOIC package constraints for PCB layout. Verify that the 3750 Vrms isolation rating meets the specific safety clearance requirements of the target application environment.

Isolators - Gate Drivers Part Context

This part belongs to the SI82F family of isolated gate drivers, which leverages Skyworks' proprietary capacitive isolation technology. Unlike optocouplers, these devices offer superior reliability and lower power consumption. The SI82F39 variant specifically targets applications needing dual-channel isolation with moderate drive strength and fast switching speeds.

Isolators - Gate Drivers Replacement Considerations

Check for direct replacements within the SI82F series, such as SI82F39ABC-IS1, noting differences in packaging format. Evaluate alternative isolators from other manufacturers only if they match the 3750 Vrms rating, 2.5 A drive current, and SOIC-16 footprint while maintaining compatible pinouts.
