FOD8314TR2

Isolators - Gate Drivers Overview

The FOD8314TR2 is a logic output optocoupler featuring a 1.0 A output current gate driver capability, designed for driving medium-power IGBTs and MOSFETs. It utilizes an AlGaAs LED coupled to a high-speed 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 offers a minimum common mode rejection of 20 kV/μs and supports a wide supply voltage range of 15 V to 30 V. It provides 5000 Vrms insulation voltage and operates within an extended industrial temperature range from -40°C to +100°C.

Isolators - Gate Drivers Feature Summary

• Integrated push-pull MOSFET output stage enables output voltage swing close to the supply rail using P-channel MOSFETs.
• Optimized IC design achieves reliable high-insulation voltage and high-noise immunity with 20kV/μs minimum common mode rejection.
• Includes under-voltage lockout (UVLO) with hysteresis for stable operation across the full operating temperature range.

Isolators - Gate Drivers Applications

• AC and brushless DC motor drives
• Industrial inverter systems
• Uninterruptible power supplies
• Induction heating equipment

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix TR2 indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to integration. Ensure the ordered part matches the SO-6 Stretched package dimensions for proper PCB footprint compatibility. Cross-reference safety approvals such as UL1577 and DIN EN/IEC60747-5-5 if regulatory certification is required for the final assembly.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring fast switching speeds and high noise immunity in isolated gate drive circuits. The 1.0 A output current is suitable for medium-power IGBT and MOSFET drivers. Consider the 8mm creepage distance of the stretched body package if higher isolation clearance is needed compared to standard SOP packages. Evaluate the 15 V to 30 V supply range against system power constraints.

Isolators - Gate Drivers Part Context

This part belongs to the FOD8314 series of gate drive optocouplers manufactured by onsemi. The series is characterized by its ability to drive medium-power semiconductor switches with high reliability. The TR2 designation typically denotes tape and reel packaging for automated assembly processes, distinguishing it from cut-tape or tube variants within the same functional family.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the FOD8314 series that may offer different packaging options or slight parameter variations. Verify pinout compatibility and electrical specifications before substituting with other gate drive optocouplers from different manufacturers.
