SI82395CD-IS

Isolators - Gate Drivers Overview

The SI82395CD-IS is a dual-channel galvanically isolated gate driver from the Si8239x series, manufactured by Skyworks Solutions. It utilizes capacitive coupling technology for signal transmission across an isolation barrier rated at 5 kVRMS. The device features a non-inverting configuration with two independent channels, each capable of sourcing and sinking 4 A output current. It operates within a supply voltage range of 12 V to 24 V and supports input logic levels between 2.5 V and 5.5 V. Key electrical parameters include a maximum propagation delay of 40 ns, rise and fall times of 12 ns, and a common-mode transient immunity of 35 kV/µs. The component is housed in a 16-pin SOIC-Wide package and is qualified under AEC-Q100 standards for automotive applications.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS' against the manufacturer's official datasheet to confirm pinout compatibility and isolation ratings. Ensure the ordering part number matches the required package type and temperature grade. Cross-reference the AEC-Q100 qualification status if automotive reliability is required. Confirm that the 5 kVRMS isolation rating meets the safety requirements of the target application circuit.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed digital isolation is required between control logic and power switches. The dual-channel architecture simplifies designs for half-bridge or full-bridge topologies. Consider the 4 A peak drive current capability for driving medium-power MOSFETs or IGBTs. The wide operating temperature range and automotive qualification make it suitable for harsh environments where standard optocouplers may lack sufficient common-mode transient immunity.

Isolators - Gate Drivers Part Context

This device belongs to the Si8239x family of isolated gate drivers, which replaces traditional optocoupler solutions. The family offers superior performance in terms of speed, power consumption, and lifetime reliability. The SI82395CD-IS specifically provides dual-channel isolation with a 5 kVRMS rating, distinguishing it from lower-rated variants in the same series. It is designed to address the increasing demand for efficient and robust power conversion in modern industrial and automotive electronics.
