SI82F39ABE-IS3

Isolators - Gate Drivers Overview

The SI82F39ABE-IS3 is a dual-channel isolated gate driver from Skyworks Solutions, featuring 6 kV isolation and SelVCD technology. It operates with a supply voltage range of 3 V to 20 V on both sides. The device provides non-inverting outputs with a peak output current of 3.5 A. Key timing parameters include a maximum propagation delay of 5 ns, rise time of 17 ns, and fall time of 18 ns. It functions within an operating temperature range of -40 °C to +125 °C and is housed in a SOIC-14 package.

Isolators - Gate Drivers Feature Summary

• Integrates Silicon dioxide (SiO2) based digital isolation for high reliability and low power consumption.
• Includes Miller clamp functionality to prevent false turn-on during high dv/dt switching events.
• Features Selectable Voltage Clamp Design (SelVCD) for enhanced noise immunity and safety certification support.

Isolators - Gate Drivers Applications

• Industrial motor drives and inverters
• Solar micro-inverters and string inverters
• Uninterruptible power supplies (UPS)
• High-frequency switching power converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'ABE' against official Skyworks documentation to confirm pinout and feature configuration, as variations exist within the SI82F39 family. Ensure the IS3 suffix matches the required lead frame plating and moisture sensitivity level specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components and confirm RoHS compliance status.

Isolators - Gate Drivers Selection Notes

Select this component when high common-mode transient immunity and robust noise rejection are critical. The 6 kV isolation rating suits applications requiring strict galvanic separation between control and power stages. The non-inverting logic simplifies interface design with standard microcontrollers. Consider the 3.5 A drive strength for medium-power MOSFETs or IGBTs where fast switching speeds are required without excessive gate resistance.

Isolators - Gate Drivers Part Context

This part belongs to the SI82Fx series of isolated gate drivers designed for demanding industrial and energy applications. It complements other variants like the SI82F39ACE-IS3 by offering specific packaging or feature configurations within the same isolation architecture. The series emphasizes safety certifications and long-term reliability through silicon dioxide insulation technology.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes within the same family include SI82F39ACE-IS3, though pinout and feature sets must be verified. Other Skyworks Si82x series devices may serve as alternatives if isolation voltage and drive current requirements align. Always validate electrical characteristics and thermal performance before swapping parts.
