SI82F39BGC-IS1R

Isolators - Gate Drivers Overview

The SI82F39BGC-IS1R is a dual-channel isolated gate driver from Skyworks Solutions, featuring 3.75 kV reinforced isolation via silicon technology and SelVCD certification. It operates with a supply voltage range of 3 V to 20 V on both sides and supports output voltages up to 30 V. The device provides non-inverting logic with a maximum propagation delay of 5 ns, rise time of 17 ns, and fall time of 18 ns. Packaged in a 14-lead SOIC (Wide) for surface mount installation, it functions within an industrial temperature range of -40 °C to +125 °C.

Isolators - Gate Drivers Feature Summary

• Integrated Miller clamp circuitry to prevent false turn-on events during high dv/dt switching conditions
• Certified Safe Electrical Voltage for Creepage and Distance (SelVCD) insulation rating for enhanced safety compliance
• High-speed signal transmission with low propagation delay suitable for high-frequency power conversion applications

Isolators - Gate Drivers Applications

• Isolated half-bridge and full-bridge gate driving in motor drives
• Power factor correction (PFC) circuits requiring galvanic isolation
• Inverter systems for renewable energy and industrial automation

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R against the manufacturer's current datasheet to confirm tape-and-reel packaging and exact pinout configuration. Ensure the selected variant matches the required isolation voltage class and package dimensions for the target PCB layout. Cross-reference the part number with official Skyworks documentation to validate RoHS compliance and recent engineering change notices before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel driver with integrated Miller clamp and certified SELVCD isolation is required. The wide operating supply range accommodates various logic levels, while the 14-pin SOIC-W package facilitates compact board designs. Consider the 3.75 kV isolation barrier for applications demanding robust noise immunity and safety certification in medium-voltage power stages.

Isolators - Gate Drivers Part Context

This device belongs to the SI82Fx family of isolated gate drivers utilizing Skyworks' proprietary silicon capacitor technology. Unlike magnetic or optical isolators, this CMOS-based solution offers superior reliability and lower power consumption. The series is designed to replace traditional transformer-based drivers in modern high-density power electronics by providing precise timing and robust fault protection.

Isolators - Gate Drivers Replacement Considerations

Direct replacements include SI82F39BGC-IS1 for tube packaging or SI82F39ACE-IS3 for 6 kV isolation requirements. Verify pin compatibility and isolation voltage ratings when substituting with other SI82 variants or competitor devices such as the Si823x series.
