The devices are optimised for automotive traction inverters and “exceed AECQ101 for automotive components”, claims the firm. “With the automotive micro-pattern trench-field-stop cell design, the IGBTs are based on technology that has already been utilised in inverter modules such as the EasyPACK 2B EDT2 or the HybridPack.” The company also highlights short-circuit robustness and creepage distance.
Breakdown voltage is 750V, supporting batteries up to 470V, rated current is up to 200A – conduction losses are said to be up to 13% less than the company’s previous generation. Max junction temperature is 175°C.
Attention has been paid to parameter distribution: “Vce(sat) difference between typical and maximum values is less than 200 mV and the gate threshold voltage difference is less than 750mV,” said Infineon. “Furthermore, the thermal coefficient is positive. Together, this enables easy parallel operation.”
There are two parts:
