Supporting Information
Overview
This product is a 4th Generation 650V IGBT bare chip ideal for automotive electric compressors and HV heaters, as well as inverters for industrial equipment.
By revising the device structure, including the process and edge termination structure, this product increases current density while reducing conduction and switching losses. In addition, despite the trade-off between lower loss and short-circuit tolerance, it ensures a long short-circuit withstand time of 7 µs at Tj = 25°C. This contributes to higher efficiency and reliability in applications.
Development Background
As electric vehicles shift to higher voltages, SiC is increasingly adopted in high-power applications such as traction inverters. At the same time, 650V IGBTs are widely used as switching devices in auxiliary systems with lower power capacity, including automotive electric compressors and HV heaters. Silicon IGBTs are also widely used in industrial equipment, particularly motors and compressors.
These applications require greater energy savings and smaller equipment designs, creating strong demand for power devices that offer higher reliability, smaller size, and higher efficiency. In particular, inverter and heater circuits require short-circuit tolerance sufficient to endure the time needed to detect and interrupt overcurrent during a short circuit.
In response to these market requirements, this product combines low-loss characteristics with high short-circuit tolerance while addressing higher-voltage requirements through a redesigned device structure.
Application Examples
◇ Automotive electric compressors
◇ Automotive HV heaters (PTC heaters, coolant heaters)
◇ Industrial equipment inverters
