• In order to stabilize the power supply line, we recommend to locate a bypass capacitor C
• In order to stabilize the detecting voltage of pin-C, we recommend to locate a capacitor C
• For the diode D, which is located between pin-C and collector of IGBT, we recommend to use a diode that

However, the rise time of the detection voltage at Pin-C varies along with the time constants of C
So, please make sure the device works properly in actual conditions.
