The NGTB40N120L3WG is an N-channel Insulated Gate Bipolar Transistor (IGBT) manufactured by onsemi. It utilizes Ultra Field Stop trench technology to achieve high performance in switching applications. The device features a maximum collector-emitter voltage of 1200 V and a continuous collector current of 40 A at 25°C. It operates with a maximum power dissipation of 341 W and supports junction temperatures up to 175°C. The component is housed in a TO-247 package for through-hole mounting, offering robust thermal management capabilities suitable for industrial power conversion systems.
Verify the specific datasheet revision when sourcing, as electrical characteristics may vary between manufacturing batches or updates. Confirm that the TO-247 pinout matches the target PCB footprint. Ensure the supplier provides traceability documentation consistent with onsemi quality standards. Check for lead-free compliance markings if required by environmental regulations.
Select this component for applications requiring 1200V blocking capability with moderate current handling around 40A. Compare switching losses against other Ultra Field Stop variants like the NGTB40N120FL3WG if lower loss is critical. Ensure the gate drive circuit can handle the input capacitance specified in the datasheet. Verify thermal resistance values align with the heatsink design constraints.
