FOD3182SDV

Isolators - Gate Drivers Overview

The FOD3182SDV is a high-speed MOSFET gate drive optocoupler manufactured by onsemi. It features a 3A output current capability and operates within a temperature range of -40°C to +100°C. The device utilizes an AlGaAs LED for input isolation and provides rail-to-rail output. Key electrical parameters include a 5000 Vrms insulation voltage, 38 ns rise time, and 24 ns fall time. It is housed in an SMD-8 Gull Wing package with a power dissipation rating of 295 mW.

Isolators - Gate Drivers Feature Summary

• High-speed operation with rapid switching characteristics suitable for demanding gate drive applications
• Robust galvanic isolation provided by an aluminum gallium arsenide (AlGaAs) light emitting diode
• Capable of sourcing and sinking 3A output current to directly drive power devices

Isolators - Gate Drivers Applications

• MOSFET gate driving
• IGBT gate driving
• Power supply control circuits

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'SDV' corresponds to the SMD-8 Gull Wing package and reel/cut tape packaging options when ordering. Confirm that the 3A output current rating aligns with the thermal management requirements of the target application. Ensure compatibility with the 5000 Vrms isolation voltage specifications required by the system design standards.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel, high-current gate driver with optical isolation is required. The FOD3182SDV is distinct from the FOD3180 series due to its higher 3A output current compared to the 2A variant. Consider the SMD-8 footprint constraints and the need for rail-to-rail output swing when evaluating alternative logic output optocouplers.

Isolators - Gate Drivers Part Context

This part belongs to the FOD318x family of high-speed MOSFET gate drive optocouplers from onsemi. The family includes variants such as the FOD3180 and FOD3184, which offer different output current capabilities and switching speeds. The FOD3182 specifically targets applications requiring a balance between high speed and significant drive current for power semiconductor switching.
