SCALE™-2 2SC0108T2Dx-xx
Preliminary Description & Application Manual
Dual Channel Ultra-compact Low-cost SCALE™-2 Driver Core

Abstract

The new low-cost SCALE™-2 dual-driver core 2SC0108T2Dx-xx combines unrivalled compactness with broad
applicability. The driver was designed for universal applications requiring high reliability. The 2SC0108T2Dx-xx
drives all usual IGBT modules up to 650V (2SC0108T2Dx-07) or 1200V (2SC0108T2Dx-12). The embedded
paralleling capability allows easy inverter design covering higher power ratings. Multi-level topologies are also
supported.
The 2SC0108T2Dx-xx is the most compact driver core available for industrial applications, with a footprint of
only 45mm x 34.3mm and an insertion height of max. 16mm. It allows even the most restricted insertion
spaces to be efficiently used.
