The onsemi FGD3440G2_F085 is a 400V N-channel IGBT in the EcoSPARK® 2 series, designed for automotive ignition applications. It features a TO-252AA (DPAK) surface-mount package with three pins. Key electrical parameters include a collector-emitter breakdown voltage of 400V and a continuous collector current of 26.9A at 25°C case temperature. The device supports logic-level gate drive with a threshold voltage of 1.7V typical. It offers a self-clamping inductive switching energy of 335mJ at 25°C and 195mJ at 150°C. Operating junction temperatures range from -40°C to +175°C, and it is qualified to AEC-Q101 standards.
Verify the manufacturer origin carefully, as Fairchild Semiconductor was acquired by onsemi. Ensure the ordering suffix matches the required package type; FGD indicates the TO-252AA SMD variant. Confirm RoHS compliance status and check for specific lot traceability requirements if mandated by your automotive quality management system.
Select this component when a robust N-channel IGBT is needed for high-voltage automotive ignition loads. The TO-252AA package suits space-constrained PCB layouts compared to through-hole alternatives like the FGP3440G2. Consider the thermal resistance and derating curves for your specific heat sink or board copper area constraints.
This part belongs to the FGB/FGD/FGP3440G2 family sharing identical electrical characteristics but differing in physical packaging. The FGD variant specifically utilizes the JEDEC TO-252AA footprint, distinguishing it from the TO-263AB (FGB) and TO-220AB (FGP) versions within the same product line.
Direct pin-compatible substitutes within the same family include FGB3440G2_F085 (TO-263AB) and FGP3440G2_F085 (TO-220AB), provided the mechanical enclosure allows for the different package dimensions.
