SI82D39AGC-IS1R

Isolators - Gate Drivers Overview

The SI82D39AGC-IS1R is a dual-channel isolated gate driver from Skyworks Solutions, utilizing capacitive coupling technology for signal transmission. It provides a high isolation voltage of 3750 Vrms and delivers a peak output current of 1 A per channel. The device operates within a supply voltage range of 3 V to 20 V on both sides and supports propagation delays as low as 32 ns. It is housed in a 16-pin SOIC package and functions with CMOS logic inputs.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling architecture ensures robust signal isolation without magnetic interference
• Dual-channel design integrates independent high-side and low-side drivers
• High surge immunity protects against transient noise in switching environments

Isolators - Gate Drivers Applications

• Industrial motor drives requiring galvanic isolation

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R corresponds to the reel packaging configuration required for your assembly line. Confirm that the 3750 Vrms isolation rating meets the safety standards of your target application region. Ensure the SOIC-16 footprint matches your PCB layout constraints before finalizing orders.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching with strong noise immunity is critical. The 1 A drive strength suits medium-power MOSFETs and IGBTs. Consider the 32 ns propagation delay for timing-sensitive bridge configurations. Verify thermal management requirements for the SOIC-16 package under continuous load conditions.

Isolators - Gate Drivers Part Context

This part belongs to the SI82 family of isolated gate drivers, which leverages silicon dioxide insulation layers. The series is designed to replace traditional optocouplers in applications demanding higher reliability and faster switching speeds. It addresses the need for compact, high-performance isolation in power electronics.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other SI82D39 variants with different packaging or temperature ratings. Cross-reference pinouts carefully when considering alternative manufacturers' dual-channel isolators to ensure compatibility with existing control signals.
