Table 1 Typical response time in function of the capacitance C

and the resistance R
thx
As the parasitic capacitances on the host PCB may influence the response time it is recommended to measure
it in the final design. It is important to define a response time which is smaller than the max. allowed short-
circuit duration of the used power semiconductor.
Note that the response time increases at DC-link voltage values lower than 550V and/or higher threshold
voltage values V
thx
. The response time will decrease at lower threshold voltage values.
Parallel connection of 2SC0435T
If parallel connection of 2SC0435T drivers is required, please consult CONCEPT’s technical support service.
3-level or multilevel topologies
If 2SC0435T drivers are to be used in 3-level or multilevel topologies, please consult CONCEPT’s technical
support service.
Desaturation protection with diode network
2SC0435T drivers are equipped with a desaturation protection function with a resistor network (see
“Collector
sense (VCEx) on page 10). If you require desaturation protection with collector sense diodes, please consult
CONCEPT’s technical support service.
