STMicroelectronics presents a new ultra fast 600V HF IGBT

 

STMicroelectronics has introduced a new ultra fast 600V HF IGBT-family, which is based on a new advanced PT Planar Technology.

The innovative Double-Drift Process, thanks to a new doping profile, significantly reduces the effective resistance in the drift region and improves the dynamic performance. The Advanced Planar Strip Layout leads to a more stable and controlled performances, especially at high temperature.

Key features

  • Operating frequency over 100kHz
  • Improved Eoff at elevated temperature
  • Minimal tail current
  • Low switching and conduction losses
  • Anti-parallel diode tailored to topology:
  • Ultra Fast (D) for hard switching (UPS, SMPS, PV and Welding)
  • Low Drop Soft Recovery (DI) for resonant, quasi-resonant or soft switching (Induction Cooker, Welding)
  • Lower Rth (TO-247 LL pack vs TO-247)

Main benefits vs previous generation (NC):

  • VCE(sat) classified for easy parallel connection
  • Lower VCE(sat) (-10%)
  • Lower turn-off losses (10% less)
  • Lower Eoff(max) (-25%) at high temperature

Targeted applications

  • Welding
  • Induction Cooker
  • PV Converter
  • UPS
  • SMPS
