STMicroelectronics HB series IGBTs

The HB series of IGBTs from STMicroelectronics are claimed to feature up to 40% lower turn-off energy losses than competing high-frequency devices while reducing conduction losses by up to 30%.

They have a minimal collector-current turn-off tail as well as low saturation voltage (Vce(sat)) down to 1.6 V (typical), minimising energy losses during switching and when turned on.

The technology produces a tight distribution window of parameters, enhancing repeatability and simplifying system design. The IGBTs can be used for efficiency of solar inverters, induction heaters, welders, uninterruptible power supplies, power-factor correction and other high-frequency power converters.

The extended voltage rating of 650 V ensures at least 600 V breakdown voltage in ambient temperatures down to -40°C for solar inverters in colder climates. The maximum operating junction temperature of 175°C and wide safe operating area increase reliability and allow smaller heatsinks.

Options include maximum current ratings from 30 to 80 A (at 100°C), a selection of popular power packages and co-packed diode optimised for resonant or hard-switching circuits.
