SI82D39ACE-IS3R

Isolators - Gate Drivers Overview

The SI82D39ACE-IS3R is a dual-channel isolated gate driver from the SI82D39 family, manufactured by Skyworks Solutions Inc. It features a 6 kVrms isolation rating and operates with a supply voltage range of 3 V to 20 V on both sides. The device provides a peak output current of 1 A per channel and supports non-inverting logic configuration. Key electrical 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 14-pin SOIC package.

Isolators - Gate Drivers Feature Summary

• Provides high-voltage galvanic isolation between control and power stages using silicon-based capacitive coupling technology.
• Delivers robust drive capability for switching devices with a 1 A peak output current per channel.
• Ensures signal integrity through low propagation delay and symmetric rise/fall times for precise timing control.

Isolators - Gate Drivers Applications

• Industrial motor drives requiring isolated high-side and low-side control
• Inverter systems in renewable energy applications such as solar microinverters
• High-frequency switching power supplies with strict isolation requirements

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS3R indicates reel packaging when ordering. Confirm that the 6 kVrms isolation rating meets system safety standards. Ensure the SOIC-14 footprint matches the PCB layout. Check for AEC-Q100 qualification if automotive compliance is required. Validate input voltage levels against the specified 3 V to 20 V range.

Isolators - Gate Drivers Selection Notes

Select this component when a balance of high isolation voltage and moderate drive current is needed. The 1 A output is suitable for medium-power MOSFETs or IGBTs. Consider the 14-pin SOIC package for standard surface-mount assembly. The wide operating temperature range supports harsh industrial environments. Compare propagation delay specifications against other drivers if precise dead-time control is critical.

Isolators - Gate Drivers Part Context

This part belongs to the SI82D39 series of isolated gate drivers. It shares the family's core architecture but differs in isolation rating and drive strength compared to variants like the SI823Hx or SI82F39. The SI82D39 specifically targets applications needing 6 kVrms isolation with 1 A drive capability.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes may include other Skyworks parts in the SI82Dxx series with matching pinouts and electrical characteristics. Verify isolation voltage and output current ratings before swapping. Cross-reference with similar 6 kV isolated drivers from other manufacturers only if pin compatibility and performance metrics align exactly.
