The NGD8201BNT4G is a Non-Punch Through (NPT) Insulated Gate Bipolar Transistor manufactured by Littelfuse. It features a collector-emitter breakdown voltage of 400V and a continuous collector current rating of 20A at 25°C. The device is housed in a DPAK-3 surface-mount package, providing a maximum power dissipation of 125W. It exhibits a saturation voltage of approximately 1.9V at 20A and includes an integrated anti-parallel diode. The component operates within a junction temperature range of -55°C to 175°C.
Verify the manufacturer designation carefully, as the NGD8201 series was originally developed by onsemi before being acquired by Littelfuse. Confirm that the specific BNT4G suffix matches the required NPT variant specifications. Ensure the documentation aligns with Littelfuse's current product portfolio standards rather than legacy onsemi datasheets to avoid discrepancies in electrical parameters or pin configurations.
Select this component for designs requiring robust short-circuit withstand capability and reliable performance under hard switching conditions. The NPT structure offers superior thermal stability compared to punch-through variants. Consider the DPAK package constraints for thermal management and ensure the gate drive voltage supports the specified saturation characteristics for optimal efficiency in power conversion systems.
This IGBT belongs to the NPT family of solid-state switches designed for high-voltage circuits. These devices are engineered to replace multiple lower-voltage switches, rectifiers, and discharge relays. The series is characterized by high power density and epoxy moldings with UL 94 V-0 flammability ratings, suitable for demanding industrial and commercial power electronics environments.
