The LGB8204ATH is a single N-channel IGBT with an integrated diode, manufactured by IXYS. It features a rated voltage of 400V and a continuous collector current of 18A. The device utilizes 5th generation Trench IGBT technology, offering low gate charge and square Reverse Bias Safe Operating Areas (RBSOA). It operates within a junction temperature range of -55°C to +175°C and is housed in a surface-mount TO-263 package.
Verify the component marking GB8204AH against official Littelfuse or IXYS datasheets to confirm authenticity. Check lifecycle status as some distributors list this part as obsolete. Ensure the TO-263 package matches the required thermal and mechanical specifications for the target assembly.
Select this component for applications requiring a 400V blocking voltage and 18A current handling in a compact surface-mount form factor. Consider the 175°C maximum junction temperature for high-thermal environments. Evaluate the low gate charge benefits for driving efficiency in high-speed switching scenarios compared to standard IGBTs.
This part belongs to the IXYS LGB series of power modules, specifically designed for automotive and industrial power electronics. It represents a transition from through-hole to surface-mount packaging while maintaining high reliability standards typical of IXYS power semiconductors.
