If the DSCP function is not used, for example during the experimental phase, SEC_TOP_VCE_IN must be connected with
SEC_TOP_GND for disabling SCP @ TOP side and SEC_BOT_VCE_IN must be connected with SEC_BOT_GND for disabling SCP @
BOT side.
The high voltage during IGBT off state is blocked by a high voltage diode.
Connection High Voltage Diode
Characteristics
Reverse blocking voltage of the diode shall be higher than the
used IGBT.
Reverse recovery time of the fast diode shall be lower than VCE
rising of the used IGBT.
Forward voltage of the diode: 1,5V @ 2mA forward current
(Tj=25°C).
A collector series resistance RVCE (1kΩ / 0,4W) must be
connected for 1700V IGBT operation.
