FOD8384R2

Isolators - Gate Drivers Overview

The FOD8384R2 is a high-speed MOSFET output optocoupler designed for gate drive applications. It features a push-pull output stage capable of delivering 2.5 A continuous and 3 A peak output current. The device provides 5000 Vrms isolation voltage and operates within a temperature range of -40°C to +100°C. Key electrical parameters include a typical forward voltage of 1.43 V, maximum DC forward current of 25 mA, and supply voltage range of 15 V to 30 V. Timing characteristics specify maximum propagation delays of 210 ns, with typical rise and fall times of 35 ns and 25 ns respectively. It is housed in a 5-SOP surface-mount package.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix R2 corresponds to the reel packaging configuration when ordering. Confirm that the 5-SOP package dimensions match the target PCB footprint. Ensure the input current limits do not exceed the specified 25 mA maximum DC forward current during design validation. Check for RoHS3 compliance requirements if applicable to the final assembly process.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching and strong gate drive current are required. The push-pull output architecture eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 35 kV/µs common-mode transient immunity for noisy environments. Compare against standard logic output optocouplers if higher speed or current drive is necessary.

Isolators - Gate Drivers Part Context

This part belongs to the FOD8384 series from onsemi, which focuses on high-performance gate driver optocouplers. The series is engineered to replace traditional transformer-based drivers in isolated power conversion applications. The R2 designation typically indicates tape and reel packaging for automated assembly processes.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes may include other onsemi parts within the FOD838x family, such as the FOD8384, provided pinout and electrical specifications remain compatible. Verify that any alternative device meets the same 5000 Vrms isolation and 3 A peak current requirements.
