FOD8314T

Isolators - Gate Drivers Overview

The FOD8314T is a gate drive optocoupler featuring an AlGaAs LED optically coupled to a high-speed driver with a push-pull MOSFET output stage. It provides a 1.0A output current capability for driving medium-power IGBTs and MOSFETs. The device utilizes a stretched body, 6-pin small outline plastic package to achieve an 8mm creepage and clearance distance, ensuring reliable high-voltage insulation. It operates within a wide supply voltage range of 15V to 30V and includes under-voltage lockout (UVLO) with hysteresis. Key electrical parameters include a maximum propagation delay of 500ns, a maximum pulse width distortion of 300ns, and a minimum common mode rejection of 20kV/μs.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix designation when ordering, as it determines the packaging format such as tube or reel. Confirm that the required insulation distance matches the 8mm specification inherent to the T-series variant. Ensure compatibility with the extended industrial temperature range requirements of the target application environment before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when high insulation voltage and noise immunity are critical for medium-power switching applications. The 8mm creepage distance makes it suitable for designs requiring strict safety compliance. Consider the 1.0A peak output current for driving moderate load capacitive gates. Verify that the 15V to 30V supply voltage range aligns with the gate drive requirements of the connected power devices.
