FOD8314

Isolators - Gate Drivers Overview

The FOD8314 is a logic output optocoupler featuring a 1.0 A output gate driver capability for medium-power IGBT and MOSFET applications. It utilizes an AlGaAs LED coupled to an integrated circuit with a push-pull MOSFET output stage. Key electrical parameters include a maximum propagation delay of 500 ns, rise time of 60 ns, and fall time of 40 ns. The device supports a continuous output current of 1.5 A and operates with a forward current of 25 mA at a forward voltage of 1.5 V. It provides 5000 Vrms insulation voltage and functions within a temperature range of -40°C to +100°C.

• Isolated IGBT and power MOSFET gate drivers

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix (e.g., TR2 for reel packaging) against the required quantity format. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the operating environment remains within the specified -40°C to +100°C industrial temperature range. Check that the input forward current does not exceed 25 mA limits during peak operation.

Isolators - Gate Drivers Selection Notes

Select this component when driving medium-power IGBTs or MOSFETs requiring 1.0 A output current. The stretched SO-6 package provides enhanced creepage and clearance distances suitable for high-voltage isolation requirements. Consider the 500 ns propagation delay for timing-sensitive applications. Ensure the system voltage stays within the 15 V to 30 V supply range for optimal UVLO performance.

Isolators - Gate Drivers Part Context

The FOD8314 belongs to onsemi’s FOD8314 series of gate drive optocouplers. It is designed for high-performance power systems where fast switching and electrical isolation are critical. The device integrates an AlGaAs LED with a specialized IC to deliver robust gate drive signals while maintaining high insulation voltage standards.

Isolators - Gate Drivers Replacement Considerations

Check datasheets for direct pin-compatible alternatives within the same series, such as the FOD8314T or FOD8314R2, which may differ only in packaging or reel specifications. Verify that any substitute maintains the 1.0 A output current capability and 5000 Vrms isolation rating.
