STGW80H65FB-4

Overview

The STGW80H65FB-4 is a trench gate field-stop IGBT from the HB series, rated at 650 V collector-emitter voltage and 80 A continuous collector current. It utilizes an advanced proprietary structure to optimize the balance between conduction and switching losses for high-efficiency frequency converters. The device features a typical VCE(sat) of 1.6 V at 80 A and supports a maximum junction temperature of 175 °C. Packaged in a TO-247 through-hole housing, it includes a Kelvin emitter pin to separate power paths from driving signals, ensuring fast switching events and safer paralleling operation due to tight parameter distribution.

Feature Summary

• Advanced trench gate field-stop structure minimizes tail current and optimizes efficiency.
• Kelvin emitter pin separates power path from driving signal for faster switching.
• Slightly positive VCE(sat) temperature coefficient enables safer paralleling.
• Very fast soft recovery antiparallel diode enhances overall switching performance.

Applications

• Industrial motor drives
• Switched-mode power supplies

Procurement Notes

Verify the exact part number against official datasheets, as suffixes like -4 may indicate specific packaging or revision variants. Confirm thermal resistance values and absolute maximum ratings before integration. Ensure ordering documentation matches the manufacturer's current specifications to avoid discrepancies in electrical characteristics or physical dimensions during procurement.

Selection Notes

Select this component when designing systems requiring a balance of low conduction loss and high switching speed within the 650 V class. The integrated fast-recovery diode simplifies circuit design by eliminating the need for external freewheeling diodes in many topologies. Consider the TO-247 package constraints for thermal management and PCB layout requirements associated with the Kelvin pin configuration.

Part Context

This device belongs to STMicroelectronics' HB series of IGBTs, which are engineered for high-frequency applications. The series focuses on minimizing both turn-on and turn-off losses while maintaining robust short-circuit withstand capability. The HB series represents a progression in trench gate technology, offering improved performance over earlier generations for demanding power conversion tasks.

Replacement Considerations

Direct substitutes include other STMicroelectronics HB series devices such as the STGW80H65DFB or STGWA80H65DFBAG, provided they meet the same voltage, current, and thermal requirements. Verify pinout compatibility and thermal resistance parameters when cross-referencing with alternative manufacturers' offerings.

FAQ

What is the purpose of the Kelvin pin on this IGBT?

The Kelvin pin separates the power emitter path from the gate drive signal path. This separation reduces noise coupling and allows for faster, more precise switching events by ensuring the gate driver sees the true emitter potential without voltage drops caused by high current flow.

Does this IGBT have an integrated anti-parallel diode?

Yes, the STGW80H65FB-4 includes a very fast soft recovery antiparallel diode. This feature improves switching performance and reduces reverse recovery losses, making it suitable for hard-switching applications without requiring external diodes.

Why is the parameter distribution important for this device?

Tight parameter distribution ensures consistent electrical characteristics across multiple units. Combined with a slightly positive VCE(sat) temperature coefficient, this allows for safer and more reliable paralleling of multiple devices to handle higher currents without significant current imbalance.
