QC841 A/1-2008 Page 1 of 2 APPLICATION EXAMPLES APPLICATION NOTES 1. The IGBT gate-emitter drive loop wiring must be shorter than one meter. 2. The IGBT gate-emitter drive loop wiring should be twisted. 3. If large voltage spike is generated at the collector of the IGBT, increase the IGBT gate resistor. 4. Pins which not be used must not be connected with the application circuit. 5. The external blocking capacitors must be connected as close as possible to the driver’s pin. 6. Peak reverse voltage of the diode D1 must be higher than the peak value of the IGBT collector voltage.
