FOD3182SV

Isolators - Gate Drivers Overview

The FOD3182SV is a high-speed MOSFET gate drive optocoupler manufactured by onsemi. It features a 3 A output current capability and operates with a single channel. The device utilizes an aluminum gallium arsenide (AlGaAs) LED for input isolation. Key electrical parameters include a 5000 Vrms insulation voltage, 10 mA forward current, and 1.43 V forward voltage. Timing characteristics specify a 38 ns rise time and 24 ns fall time. The component supports a reverse voltage of 5 V and dissipates up to 295 mW. It functions within a temperature range of -40°C to +100°C and is housed in an SMT-8 package.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'SV' against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the Mouser part number 512-FOD3182SV with official onsemi records to validate authenticity and manufacturing origin before finalizing orders.

Isolators - Gate Drivers Selection Notes

Select this component when a high-output current of 3 A is required for direct MOSFET gate driving without external amplification. The high-speed performance makes it suitable for applications requiring fast switching transitions. Consider the SMT-8 package constraints and thermal dissipation limits of 295 mW during PCB layout design to ensure reliable operation under maximum load conditions.

Isolators - Gate Drivers Part Context

The FOD3182SV belongs to the FOD3182 series of high-speed optocouplers from onsemi. This series is designed specifically for power electronics applications requiring isolated gate drive signals. The device integrates an AlGaAs LED with a dedicated output stage to provide enhanced noise immunity and fast response times compared to standard phototransistor-based isolators.

Isolators - Gate Drivers Replacement Considerations

The FOD3180SV is a related logic output variant within the same family. Verify if push-pull output requirements align with the FOD3180SV specifications before substitution. Ensure compatibility with existing PCB footprints and isolation voltage ratings when considering alternative models.
