Key Features

  • 650 V VCES and 80 A IC rating for high-power switch-mode and motor-drive applications
  • 283 W maximum power dissipation supported by large TO-247 through-hole package and heatsink mounting
  • 20 V gate-emitter voltage maximum enabling standard IGBT gate driver compatibility
  • N-channel type for straightforward high-side and low-side switch topologies in H-bridge designs
  • JESD-609 e3 rating confirms Pb-free, RoHS-compliant construction
  • YTEOL of 6 years indicating active production availability for industrial power converter designs

Applications

The STGWT40H65DFB is used in three-phase motor inverters, solar-panel string inverters, and industrial servo drives where its 650 V / 80 A capability handles the high bus voltages and peak currents characteristic of 400 V AC mains-fed power stages. It also suits UPS, welding equipment, and induction heating power supplies that require robust switching performance and reliable heatsink mounting in demanding 283 W continuous dissipation environments.

Frequently Asked Questions

What are the voltage and current ratings of the STGWT40H65DFB, and which inverter topologies can it support?

The STGWT40H65DFB is rated for 650 V collector-emitter voltage and 80 A maximum collector current, with a 20 V gate-emitter voltage limit. These ratings are well matched to half-bridge and full-bridge inverter topologies operating from 400 V AC rectified bus rails, covering single-phase and three-phase motor drives up to approximately 20 kW.

How should the STGWT40H65DFB be thermally managed given its 283 W maximum power dissipation?

The device is packaged in a through-hole vertical TO-247-style case that mounts directly to an external heatsink via a bolt or clip. To dissipate the full 283 W at maximum current, the heatsink thermal resistance must be low enough to keep the junction below the maximum rated temperature; a heatsink with thermal resistance below 0.3 °C/W is typically required when derating is not possible.

Is the STGWT40H65DFB compatible with standard IGBT gate driver ICs, and what gate voltage does it require?

Yes. The gate-emitter voltage maximum is 20 V, which is fully compatible with common IGBT gate driver ICs that deliver +15 V / -5 V or +15 V / -8 V gate drives. The positive 15 V gate-on voltage provides adequate saturation voltage reduction, while the negative turn-off voltage helps suppress parasitic turn-on in bridge configurations operating at high dV/dt.

What is the lead time and lifecycle outlook for the STGWT40H65DFB in industrial power design programs?

The factory lead time is 15 weeks, and the YTEOL indicator is 6 years, confirming the part remains in active production. Industrial power converter programs that expect 5-year production runs can design in the STGWT40H65DFB with reasonable confidence, but a safety stock buffer of at least 16 weeks is advisable to absorb lead-time variability for this discrete through-hole power device.
