Onsemi launches 1200V IGBTs
New 1200 V devices said to offer the best conduction and switching performance on the market
Onsemi has announced a new range of ultra-efficient 1200 V IGBTs that minimise conduction and switching losses. Intended to enhance efficiency in fast switching applications, the new devices will be primarily used in energy infrastructure applications like solar inverters, uninterruptible power supplies (UPS), energy storage and EV charging power conversion.
The new 1200 V Trench Field Stop VII (FS7) IGBTs are used to boost input to high voltage (Boost stage) as well as the inverter to provide an AC output in high switching frequency energy infrastructure applications. The low switching losses of FS7 devices enable higher switching frequencies that reduce the size of magnetic components, increasing power density and reducing system cost. For high-power energy infrastructure applications, the positive temperature coefficient of FS7 devices enables easy parallel operation.
“As efficiency is extremely critical in all high switching frequency energy infrastructure applications, we focused on reducing turn-off switching losses and providing the best switching performance in this new range of IGBTs,” said Asif Jakwani, senior vice president and general manager of the Advanced Power Division, part of the Power Solutions Group at Onsemi.
The FS7 devices include high-speed (S-series) and medium-speed (R-Series) options. All devices include an optimised diode for low VF, tuned switching softness and can operate with junction temperatures (TJ) up to 175°C. The S-Series devices, like FGY75T120SWD, offer the best switching performance among currently available 1200 V IGBTs in the market.
Tested with currents up to 7 times the rated value, this highly rugged IGBT platform also offers best-in-class latch-up immunity. The R-Series is optimised for medium-speed switching applications, such as motor control and solid-state relay in which conduction losses are dominant occurs. FGY100T120RWD shows a VCESAT as low as 1.45 V at 100A, an improvement of 0.4 V over previous generation devices.
The FS7 devices are available in a range of package styles including TO247-3L, TO247-4L, Power TO247-3L and as bare die, giving designers flexibility and design options.
