SI82E39BCE-IS3

Isolators - Gate Drivers Overview

The SI82E39BCE-IS3 is a dual-channel isolated gate driver from Skyworks Solutions, designed for high-voltage power switching applications. It features a 6 kV isolation rating and operates with a supply voltage range of 5 V to 30 V on the output side. The device provides non-inverting logic configuration and includes an active shutdown function. Key electrical parameters include a maximum propagation delay of 65 ns, with rise and fall times of 8.3 ns and 8.6 ns respectively. It functions within a temperature range of -40°C to +125°C and utilizes a SOIC-14 surface-mount package.

Isolators - Gate Drivers Feature Summary

• Provides 6 kV reinforced isolation between input and output channels for safe high-voltage operation.
• Delivers dual-channel drive capability with independent high-side and low-side outputs.
• Integrates an active shutdown pin to force both outputs to a defined state instantly.
• Supports non-inverting logic inputs for straightforward control interface compatibility.

Isolators - Gate Drivers Applications

• Industrial motor drives and inverters requiring robust galvanic isolation
• Uninterruptible power supplies (UPS) and battery management systems
• Solar inverter topologies utilizing insulated gate bipolar transistors or MOSFETs
• High-frequency switched-mode power supplies with strict isolation requirements

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS3 against the manufacturer's latest datasheet to confirm package type and isolation certification level. Ensure the ordering part number matches the required reel quantity if tape-and-reel packaging is needed, as tube options may differ. Cross-reference the RoHS status and material compliance declarations with current regulatory standards before finalizing procurement contracts.

Isolators - Gate Drivers Selection Notes

Select this component when a 6 kV isolation barrier is mandatory for system safety and noise immunity. The 65 ns propagation delay suits moderate-speed switching applications where precise timing alignment is less critical than in ultra-fast converters. Confirm that the 5 V to 30 V output supply range aligns with the target gate drive voltage requirements of the connected power devices.

Isolators - Gate Drivers Part Context

This device belongs to the SI82E39 family of isolated gate drivers, which emphasizes high reliability and compact form factors. The series is engineered for demanding environments where traditional optocouplers lack sufficient speed or longevity. The SOIC-14 package allows for efficient PCB layout in space-constrained designs while maintaining adequate creepage and clearance distances for high-voltage isolation.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes within the same isolation class include the SI82E39ACE-IS3 variant, which offers similar performance characteristics. Verify pinout compatibility and thermal dissipation capabilities when transitioning between different package styles or minor revision codes within the manufacturer's portfolio.
