Based on trench field-stop (TFS) technology, the 1200 V IGBT S series is designed for applications working at very low frequencies (up to 8 kHz). Optimized for the lowest combined conduction and turn-off losses, they enable designers to increase the power-conversion efficiency of UPS, solar generators, welders and industrial motor drives.
In addition, the S series IGBTs feature the lowest VCE(sat) among 1200 V IGBTs currently on the market, which ensures a lower voltage drop and minimizes power dissipation thereby simplifying thermal management.

A 10 µs minimum short-circuit withstand time (at 150 °C starting junction temperature) combined with an extended maximum operating junction temperature of 175 °C and a wide safe operating area (SOA), ensures device reliability and ruggedness.

Available in 15 A, 25 A and 40 A current ratings in standard or long-lead TO-247 packages, the 1200 V IGBT S series delivers an optimal trade-off between conduction and switching performance combined with outstanding robustness and EMI performance.

Main characteristics:

  • Lowest VCE(sat) among 1200 V IGBTs currently on the market
  • Low voltage drop IGBT series tailored for high power industrial drives with a switching frequency up to 8 kHz
  • High robustness and reliability thanks to 1200 V breakdown voltage, 10 µs min. short-circuit rating (at 150 °C starting TJ) and extended max operating TJ of 175 °C
  • Thin IGBT die for increased thermal resistance
  • Positive VCE(sat) temperature coefficient, with tight parameter distribution, for design simplification and easy paralleling
  • Optimized diode for fast recovery (high level of softness, low EMI and turn-on losses)

Ideal for hard-switching topologies up to 8 kHz, ST’s 1200 V IGBT S series complements ST’s 1200 V IGBT M series and H series, which are designed for optimum efficiency at up to 20 kHz and over 20 kHz respectively.
