650V CoolSiC Hybrid IGBT Discrete,
Infineon 650V TRENCHSTOP 5 IGBT and
Unipolar Structure Schottky Barrier CoolSiC Bonding


Infineon Technologies AG announced today the launch of its 650 V CoolSiC™ hybrid IGBT discrete family. The family combines the 650 V TRENCHSTOP™ 5 IGBT technology with a unipolar Schottky barrier CoolSiC diode.

It is suitable for DC/DC converters and power factor correction (PFC) with high switching frequency and low switching loss, and can be used in battery charging infrastructure, energy storage solutions, solar inverters, uninterruptible power supplies (UPS), servers or telecom SMPS.

CoolSiC hybrid IGBTs integrate an IGBT and a freewheeling SiC Schottky barrier diode into the package, reducing switching losses with nearly constant dv/dt and di/dt values during operation. Compared to standard silicon diode solutions, Eon is reduced by up to 60% and Eoff by up to 30%.

Additionally, the switching frequency can be increased by up to 40% while maintaining the output power requirement. Increasing the switching frequency allows the size of passive components to be reduced. Replacing TRENCHSTOP 5 IGBTs with hybrid IGBTs can improve efficiency by 0.1% for every 10 kHz switching frequency without any design changes.

Infineon says the new product family will act as a bridge between pure silicon solutions (Si) and high-performance SiC MOSFET designs. Compared to pure Si designs, hybrid IGBTs improve electromagnetic compatibility and system reliability, and the unipolar characteristics of Schottky barrier diodes allow the diodes to switch quickly without risk of severe oscillation or parasitic turn-on.

Customers can choose between the TO-247-3pin package or the TO-247-4pin Kelvin emitter package. The fourth pin in the Kelvin emitter package enables a very low inductance emitter control loop, reducing overall switching losses.

The CoolSiC hybrid discrete IGBT family is available for order now. It includes 40 A, 50 A and 75 A 650 V TRENCHSTOP 5 ultra-fast H5 IGBTs with half the rated CoolSiC Gen 6 diodes, as well as medium-speed S5 IGBTs with the same rated CoolSiC Gen 6 diodes.
