2SC0435T Description and Application Manual 

 
Dual-Channel High-power Low-cost IGBT Driver 
 

Abstract 

The new low-cost SCALE-2 dual-driver core 2SC0435T combines unrivalled compactness with broad 
applicability. The driver was designed for universal applications requiring high reliability. The 2SC0435T drives 

all usual high-power IGBT modules up to 1700V. The embedded paralleling capability allows easy inverter 

design covering higher power ratings. Multi-level topologies are also supported. 
The 2SC0435T is the most compact driver core in its power range available for industrial applications, with a 

footprint of only 57.2 x 51.6mm and an insertion height of max. 20mm. It allows even the most restricted 

insertion spaces to be efficiently used.
