CoolSiC™ Hybrid Devices
Silicon Carbide (SiC) diodes and transistors are key components for modern and innovative power electronic
Use of SiC diode in combination with silicon IGBT allows to extend capabilities of IGBT technology reaching the next level efficiency with hybrid IGBT power switches. The CoolSiC™ hybrid products create the price-performance bridge between pure Si-solution and high performance of entirely SiC MOSFET designs.
- CoolSiC™ Hybrid Discretes: Fast plug & play upgrade of available discrete designs to a higher efficiency, as a rule of thumb – 0.1% efficiency increase for each 10kHz – i.e. 0.23% efficiency increase for working frequency of 23kHz.
- CoolSiC™ Hybrid Modules: Form the ideal bridge between purely Silicon-based and Silicon Carbide solutions. They combine IGBT chips with SiC diodes to further extend the capacity of the IGBT technology.

Ultra low switching losses comparable to SiC MOSFET
The new CoolSiC™ Hybrid Device co-packed with SiC diode significantly reduces switching losses at almost unchanged dv/dt and di/dt values. Ultra fast IGBTs in Kelvin-emitter 4-pin packages enable reduction of switching losses at the expense of higher dv/dt or di/dt values (and thus worse EMC). Fast switching S5 TRENCHSTOP™ 5 650 V IGBT or ultra fast switching H5 TRENCHSTOP™ 5 IGBT co-packed with free- wheeling Gen6 SiC diode in TO-247- 4pin package.
