The FGB40N60SM is a Field Stop IGBT manufactured by onsemi, designed for high-efficiency power switching applications. It features a collector-emitter breakdown voltage (VCEO) of 600 V and a continuous collector current (Ic) of 40 A at 25°C. The device utilizes second-generation Field Stop technology to achieve low saturation voltage and fast switching characteristics. Key electrical parameters include a typical VCE(sat) of 1.9 V at Ic = 40 A and an off-state energy loss (Eoff) of 6.5 µJ/A. It operates within a junction temperature range of -55°C to +175°C and is housed in a TO-247 package.
Verify the specific suffix against official documentation to confirm automotive qualification status. Confirm RoHS compliance and packaging details directly with the manufacturer or authorized distributors before procurement. Ensure ordering information matches the exact part number variant required for the application.
Select this component for designs requiring robust 600V switching with low conduction losses. Evaluate thermal management requirements based on the 349 W power dissipation rating. Consider the positive temperature coefficient for potential parallel configurations to increase current handling capacity in high-power applications.
This device belongs to the FGH/FGB series of Field Stop IGBTs from onsemi (formerly Fairchild Semiconductor). These components are engineered to replace older standard IGBT technologies in applications demanding higher efficiency and reduced heat generation. The series is widely recognized for its reliability in industrial and renewable energy power conversion systems.
Direct replacements may include the FGH40N60SMD or FGH40N60SM variants from the same manufacturer family. Verify pinout compatibility and electrical parameter tolerances when substituting. Cross-referencing with other manufacturers' 600V 40A Field Stop IGBTs requires careful validation of switching speeds and thermal resistance values.
