FOD8343TR2

Isolators - Gate Drivers Overview

The FOD8343TR2 is a high-speed gate drive optocoupler manufactured by onsemi, housed in a stretched body SOP-6 package. It features a single channel with push-pull output configuration and provides 5000 Vrms insulation voltage. The device supports a maximum continuous output current of 4.0 A, with a forward current of 16 mA and forward voltage of 1.5 V. Key timing parameters include a rise time of 38 ns and a fall time of 24 ns. It operates within a temperature range of -40°C to +100°C and has a power dissipation rating of 500 mW.

Isolators - Gate Drivers Feature Summary

• High-speed gate drive capability with 4.0 A output current for efficient switching
• Stretched body SOP-6 package design for enhanced creepage and clearance distances
• Push-pull output stage providing strong drive capability for power devices

Isolators - Gate Drivers Applications

• Gate drive isolation for IGBTs and MOSFETs in motor drives
• Isolation interfaces in industrial inverters and converters
• Power supply control circuits requiring high-speed signal transmission

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix TR2 indicates tape and reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the stretched body SOP-6 footprint matches the target PCB layout constraints. Validate thermal management requirements against the 500 mW power dissipation limit under operating conditions.

Isolators - Gate Drivers Selection Notes

Select this component when a 4.0 A output current is required for driving power switches. Compare with the FOD8342 if a lower 3.0 A output current suffices for the application. Consider the 5000 Vrms isolation rating for safety-critical designs. Evaluate the 38 ns rise time against system switching frequency requirements to ensure adequate speed without excessive noise.

Isolators - Gate Drivers Part Context

This part belongs to the FOD8343 series of high-speed optocouplers designed specifically for gate drive applications. It shares the same package and basic electrical characteristics as other variants in the family but is distinguished by its 4.0 A output current capability. The series addresses the need for reliable isolation in high-power electronic systems.

Isolators - Gate Drivers Replacement Considerations

The FOD8342TR2 is a related variant offering 3.0 A output current in the same package. Verify if the reduced current capacity meets the load requirements before substitution. No direct pin-compatible substitutes with different current ratings are confirmed in public data.
