6SP0235T Description & Application Manual

Driver solution for HybridPACK

TM

2 IGBT modules with an electrical interface

Abstract

The 6SP0235T is a six-channel driver with an electrical interface. The driver is based on CONCEPT’s SCALE-2
chipset, a highly integrated technology for the reliable driving and safe operation of IGBTs.
Perfectly matched driver versions are available for HybridPACK

TM

2 IGBT modules. The plug-and-play capability

of the driver allows immediate operation after mounting. The user needs invest no effort in designing or

adjusting it to a specific application.
