FOD3120TV

Isolators - Gate Drivers Overview

The FOD3120TV is a single-channel gate driver optocoupler manufactured by onsemi. It provides electrical isolation with a rated voltage of 5000Vrms and supports through-hole mounting in an 8-MDIP package. The device delivers a peak output current of 3A, with continuous high and low currents of 2A each. It operates within an output supply voltage range of 15V to 30V. Key timing parameters include maximum propagation delays of 400ns for both rising and falling edges, with typical rise and fall times of 60ns. The unit exhibits a minimum common-mode transient immunity of 35kV/µs and a maximum pulse width distortion of 100ns. It functions reliably across a temperature range of -40°C to 100°C.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'TV' corresponds to the tube packaging configuration when ordering. Confirm that the 8-MDIP package dimensions align with the target PCB footprint. Ensure the input forward current requirements do not exceed the specified maximum DC forward current limit during system design validation.

Isolators - Gate Drivers Selection Notes

Select this component when a single isolated channel with 5000Vrms isolation capability is required. It is suitable for applications needing a 3A peak drive current. Consider the 8-DIP package constraints and the 15V-30V output supply range. Evaluate if the 400ns propagation delay meets the switching frequency requirements of the target power stage.

Isolators - Gate Drivers Part Context

This part belongs to the FOD3120 family of gate drive optocouplers from onsemi. These devices are engineered for medium-power switching applications. The family typically offers variations in packaging and insulation ratings while maintaining similar drive capabilities for IGBTs and MOSFETs.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the FOD3120 series or equivalent parts from other manufacturers offering 3A peak current and 5000Vrms isolation in an 8-pin DIP package. Verify pinout compatibility and electrical parameter equivalence before substitution.
