New and improved IGBTs M-series 1200V IGBTs from ST

New and improved M-series 1200V IGBTs from STMicroelectronics designed using trench-gate field-stop technology target applications such as solar inverters, welding equipment, uninterruptible power supplies, and industrial motor drives.

Conduction and turn-off characteristics are optimized with low turn-on losses, and these IGBTs can switch upto 20kHz. They offer max operating temperature of 175°C, a wide safe operating area (SOA) with latch-up free operation, and short-circuit withstand time of 10µs at 150°C ensure rugged performance in harsh ambient and electrical environments.

These IGBTs minimizes voltage overshoot and eliminates oscillation during switch-off, thereby reducing energy losses and simplifying circuit design. At the same time, low saturation voltage (Vce(sat)) ensures high conduction efficiency. The positive temperature coefficient and tight parameter distribution of Vce(sat) simplify paralleling of devices for increased power-handling capability.

Special diode is co-packaged in anti-parallel with the IGBT, provides fast recovery time and enhanced softness without significantly increasing turn-on losses, resulting in improved EMI performance.

The 40A STGW40M120DF3, 25A STGW25M120DF3, and 15A STGW15M120DF3 in standard TO-247 package, and the STGWA40M120DF3, STGWA25M120DF3 and STGWA15M120DF3 in TO-247 long-lead package, are in mass production now. Prices start from $2.80 for the STGW15M120DF3, for orders of 1000 units.
