SI82398CD-AS3R

Isolators - Gate Drivers Overview

The SI82398CD-AS3R is a dual-channel, current-isolated gate driver from the Skyworks Si8239x series. It features a 3250 Vrms isolation voltage and operates within a temperature range of -40°C to +125°C. The device provides high-speed switching with a maximum propagation delay of 40 ns, rise time of 12 ns, and fall time of 12 ns. It supports a peak output current of 4 A and dissipates up to 2.1 W of power. Packaged in a 14-SOIC (wide) surface-mount format, it is designed for robust industrial applications requiring galvanic isolation.

Isolators - Gate Drivers Feature Summary

• Delivers high electromagnetic immunity suitable for noisy industrial environments.
• Features non-inverting logic configuration for straightforward signal interfacing.

Isolators - Gate Drivers Applications

• Industrial motor drives
• Inverter systems
• High-voltage power supplies

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'AS3R' against official Skyworks documentation to confirm reel packaging and exact UVLO thresholds. Ensure compatibility with existing PCB footprints for the 14-SOIC wide package. Confirm that the 3250 Vrms isolation rating meets system safety requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching and robust isolation are required. The 4 A output current capability suits medium-power MOSFETs and IGBTs. The 14-pin SOIC package offers a compact solution compared to wider 16-pin variants. Consider the 3250 Vrms rating for applications demanding higher isolation margins than standard 2500 Vrms devices.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of isolated gate drivers. It shares core performance characteristics with other members like the SI82398CD-IS3R but differs in packaging and potentially specific electrical tolerances defined by the AS3R suffix. The family is characterized by low propagation delay and high common-mode transient immunity.
