FGD3040G2

Overview

The FGD3040G2 is an EcoSPARK® 2 ignition coil driver designed for advanced multi-spark, high-current ignition systems with lean burn requirements. It integrates a self-clamping inductive switching (SCIS) feature to manage energy dissipation during switching events. The device operates with a logic-level gate drive and meets AEC-Q101 automotive qualification standards. Key electrical parameters include a collector-emitter saturation voltage of 1.15 V and a continuous collector current capability of 25.6 A at 25°C. The SCIS energy rating is specified at 300 mJ at a junction temperature of 25°C. The component is housed in a DPAK surface-mount package.

Feature Summary

• EcoSPARK® 2 technology reduces VSAT by up to 20% while maintaining SCIS energy levels, lowering power consumption and operating junction temperatures.
• Integrated self-clamping inductive switching (SCIS) functionality supports high-performance ignition coils without requiring external clamping components.
• Logic-level gate drive simplifies interface with standard ignition control units.
• AEC-Q101 qualified for reliability in harsh under-hood automotive environments.

Applications

• Advanced multi-spark ignition systems
• High-current ignition coil drivers
• Lean burn engine management systems

Procurement Notes

Verify the specific revision status and manufacturing origin when sourcing this component, as Fairchild Semiconductor's automotive product lines have undergone corporate transitions. Confirm that the delivered parts match the original Fairchild specifications rather than generic equivalents, ensuring compliance with the required AEC-Q101 standards for your application.

Selection Notes

Select the FGD3040G2 when designing ignition circuits that require reduced thermal management due to lower power dissipation. Compare its 300 mJ SCIS energy rating against system requirements. Ensure the DPAK package fits the PCB layout constraints. Verify compatibility with the driving logic voltage levels, as the device utilizes a logic-level gate drive architecture.

Part Context

This part belongs to the EcoSPARK® 2 family of ignition coil drivers from Fairchild Semiconductor. It serves as a direct successor to previous generations, offering improved efficiency in a smaller footprint. The FGD3040G2 is often compared with the FGD3440G2, which offers higher SCIS energy capacity. Both are designed to replace older discrete solutions or earlier generation drivers in modern vehicle architectures.

Replacement Considerations

The FGP3040G2-F085 is a related IGBT variant but differs in packaging (TO-220-3 vs DPAK) and configuration. Direct pin-to-pin replacement requires verifying the package type and thermal characteristics. No other identical substitutes are confirmed in public documentation.
