STGW40H65FB

Overview

The STGW40H65FB is an N-channel Insulated Gate Bipolar Transistor (IGBT) manufactured by STMicroelectronics. It features a maximum continuous collector current of 80 A and a collector-emitter voltage rating of 650 V. The device utilizes a trench gate field-stop structure to optimize the balance between conduction and switching losses. Key electrical parameters include a maximum power dissipation of 283 W, a typical collector-emitter saturation voltage of 1.6 V at 40 A, and a maximum gate-emitter voltage of ±20 V. It operates within a temperature range of -55°C to +175°C and is housed in a TO-247 package for through-hole mounting.

Feature Summary

• Trench gate field-stop technology minimizes tail current and saturation voltage for high efficiency.
• Kelvin emitter pin separates power path from driving signal to enable faster switching events.
• Positive VCE(sat) temperature coefficient ensures safer paralleling operation with tight parameter distribution.

Applications

• High-frequency frequency converters
• Industrial motor drives
• Uninterruptible power supplies (UPS)
• Welding equipment

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical characteristics and packaging options. Ensure the component matches the required thermal resistance and switching speed specifications for the target application. Cross-reference part numbers with authorized distributors to avoid counterfeit products. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this IGBT when a balance between low conduction loss and fast switching is required. The trench gate field-stop structure makes it suitable for applications operating at higher frequencies compared to standard planar devices. Consider the thermal management requirements given the 283 W power dissipation rating. Evaluate the need for the Kelvin pin if minimizing switching noise and improving drive performance are critical design constraints.

Part Context

This component belongs to the HB series of IGBTs from STMicroelectronics. The series is designed to provide an optimum compromise between conduction and switching losses. It represents an advancement over previous generations by incorporating advanced trench gate field-stop structures. This positioning targets high-efficiency power conversion systems where both dynamic and static performance are important.

Replacement Considerations

Direct substitutes may include other STMicroelectronics IGBTs from the same HB series or H series with similar voltage and current ratings. Verify pin compatibility and thermal characteristics before substitution. Other manufacturers' 650 V, 40-80 A trench-gate IGBTs may be compatible if electrical parameters and package dimensions align precisely.
