SI82F39ACE-IS3

Isolators - Gate Drivers Overview

The SI82F39ACE-IS3 is a dual-channel isolated gate driver from Skyworks Solutions, designed for high-voltage power switching applications. It features a 6 kV reinforced isolation rating compliant with SelVCD standards. The device integrates both high-side and low-side drivers in a single SOIC-14 package. Key electrical specifications include a peak output current of 3.5 A, a maximum propagation delay of 5 ns, and rise/fall times of 17 ns and 18 ns respectively. It operates on a supply voltage range of 3 V to 20 V and supports logic inputs within the same voltage window. The component is rated for an operating temperature range from -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Provides 6 kV reinforced insulation (SelVCD) for safety-critical isolation between control and power stages.
• Integrates two independent channel drivers capable of sourcing and sinking 3.5 A peak currents.
• Delivers fast switching performance with a maximum propagation delay of 5 ns and symmetric rise/fall times.
• Supports non-inverting logic configuration with wide supply voltage compatibility.

Isolators - Gate Drivers Applications

• Isolated switched-mode power supplies
• Motor drive systems
• Power inverters
• Uninterruptible power supplies (UPS)
• Onboard chargers

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS3 against the manufacturer's official datasheet to confirm pinout and isolation ratings. Ensure the selected package variant matches the required PCB footprint. Confirm RoHS compliance status through the latest documentation. Validate that the 6 kV isolation rating meets the specific safety standards required by the end application. Cross-reference the part number with authorized distributors to ensure authenticity.

Isolators - Gate Drivers Selection Notes

Select this component when high-voltage isolation and fast switching speeds are critical. The 3.5 A drive strength suits medium-power IGBTs and MOSFETs. Consider the SOIC-14 package constraints for thermal management. Compare propagation delay requirements against other family members if tighter timing is needed. Verify input voltage levels match the control logic interface.
