Key Features

  • 650 V collector-emitter voltage and 40 A continuous collector current (80 A peak) handle high-power switching in 3-phase motor drives and solar inverters
  • Trench gate field-stop technology reduces conduction losses and tail current for switching frequencies up to 30 kHz, improving inverter efficiency
  • D2PAK (TO-263AB) surface mount package enables high power dissipation on PCB copper pours without requiring a separate heat sink clip

Applications

The STGB40H65FB is designed for high-frequency motor control inverters, power factor correction circuits, and induction heating systems operating from 400 V AC mains where a 650 V rated IGBT is required. Its trench gate field-stop construction delivers a balance of low switching losses and low conduction losses, making it well suited for variable-speed drives, UPS systems, and photovoltaic string inverters in the 1 kW to 5 kW power range.

Frequently Asked Questions

What are the voltage and current ratings of the STGB40H65FB, and which power levels do they support?

The STGB40H65FB is rated at 650 V collector-emitter and 40 A continuous collector current, with a peak of 80 A. These ratings support single-phase and 3-phase inverter designs in the 1 kW to 5 kW range operating from 230 V or 400 V AC mains.

How does the trench gate field-stop technology in the STGB40H65FB improve efficiency at switching frequencies above 10 kHz?

Trench gate field-stop construction reduces gate charge by approximately 30% and minimizes tail current at turn-off compared to standard planar IGBTs, lowering switching losses by up to 25% at 20 kHz, which improves inverter efficiency by 0.5% to 1% in motor drive applications.

What PCB thermal management is needed to run the STGB40H65FB at full 40 A in a D2PAK footprint?

At 40 A continuous, the STGB40H65FB dissipates up to 20 W to 30 W depending on duty cycle. A D2PAK copper pour of at least 25 cm² on a 2 oz copper layer is needed to keep junction temperature below 150°C without an external heat sink, or a clip-on heat sink rated at 5°C/W or better can be used for higher ambient temperatures.

When is the STGB40H65FB preferred over a SiC MOSFET in a 3 kW inverter design?

At switching frequencies below 20 kHz and in cost-sensitive designs, the STGB40H65FB offers lower component cost than a comparable 650 V SiC MOSFET while delivering adequate efficiency. For a 3 kW motor drive at 16 kHz, the IGBT solution can cut component cost by 40% to 60% with less than 0.5% efficiency penalty versus SiC.
