he 650 V IGBT HB2 series, based on trench field-stop (TFS) technology and optimized for applications working at a switching frequency between 16 and 60 kHz, represents a step forward for the HB series. IGBTs belong to the STPOWER family. 

These medium/high-speed HB2 IGBT series combine a lower saturation voltage (1.55 V typ.) and lower total gate charge compared to the previous HB series, ensuring a minimized overshoot voltage during turn-off, even with small gate resistance, and lower turn-off energy, being the best choice for welding machines, PFC converters, UPS, solar inverters and DC chargers applications. The HB2 series, covering a wide current capability from 15 to 100A, offers a product portfolio with three different diode options (protection diode, half-rated and full-rated diode) and in an extensive power package choice (D2PAK, TO-220, TO-220FP, TO-247 Long Leads and TO-247 4L). 

|| NEW || The HB2 series has been enlarged with 3 new STPOWER IGBTs including 50, 75 and 100 A devices housed in the high-performance TO247-4 leads package. The new IGBTs enhance switching performance thanks to the extra driving kelvin pin in addition to the benefits offered by the outstanding HB2 series. The new 4-lead package significantly decreases turn-on switching energy ensuring an increased overall system efficiency in solar inverters and UPS.

To enhance single-phase PFC and boost topology applications and avoid accidental reverse overvoltage across collector to emitter terminals, ST offers dedicated products, ranging from 20 to 50A, with embedded protection diode in TO-247 Long leads package and belonging to HP2 sub-series.

STPOWER IGBT main characteristics:

  • Very low VCE(sat) (1.55 V typ.)
  • Low QG
  • High robustness and reliability
  • Maximum operating TJ of 175 °C

Our wide STPOWER product portfolio combined with state-of-the art packaging and protections for high reliability and safety helps designers find the right solutions for customized, high-efficiency applications that will last a long lifetime.
