The STGWT40H65FB is an N-channel Insulated Gate Bipolar Transistor manufactured by STMicroelectronics. It features a maximum continuous collector current of 80 A and a maximum collector-emitter voltage of 650 V. The device is housed in a TO-3P package designed for through-hole mounting. Key electrical parameters include a maximum power dissipation of 283 W, a maximum collector-emitter saturation voltage of 2.3 V, and a maximum gate-emitter voltage of ±20 V. It operates within a temperature range of -55 °C to +175 °C and supports switching speeds up to 1 MHz.
Verify the specific suffix 'FB' against the manufacturer's official datasheet to confirm pinout configuration and internal diode characteristics. Ensure the TO-3P package dimensions match the target PCB footprint. Confirm RoHS compliance status if required by local regulations. Cross-reference the part number with authorized distributors to avoid counterfeit components.
Select this component when a high-voltage IGBT with robust current handling is required for industrial power conversion. The TO-3P package facilitates efficient heat sinking compared to surface-mount alternatives. Consider the thermal resistance and saturation voltage trade-offs against other HB series variants based on the specific switching frequency and conduction loss requirements of the design.
This device belongs to the HB series of IGBTs from STMicroelectronics. The series is engineered to balance conduction and switching losses, maximizing efficiency in frequency converters. The trench gate field-stop structure provides improved switching speed and reduced tail current compared to standard planar technologies.
Compatible substitutes within the same family include STGW40H65FB and STGB40H65FB. Verify that alternative packages or suffixes maintain identical pin configurations and electrical ratings before substitution.
