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.

Page 3: Driver Overview
Target Driver Overview The 2SC0435T is a driver core equipped with CONCEPT’s latest SCALE-2 chipset /1/. The SCALE-2 chipset is a set of application-specific integrated circuits (ASICs) that cover the main range of functions needed to design intelligent gate drivers. The SCALE-2 driver chipset is a further development of the proven SCALE technology /2/. - Page 4 2SC0435T Description and Application Manual Mechanical Dimensions Fig. 3 Mechanical drawing The primary side and secondary side pin grid is 2.54mm (100mil) with a pin cross section of 0.64mmx0.64mm. Total outline dimensions of the board are 57.2mmx51.6mm. The total height of the driver is max.

Page 6: Recommended Interface Circuitry For The Primary Side Connector
The connecting distance between ground pins must be kept at a minimum. Description of Primary Side Interface General The primary side interface of the driver 2SC0435T is very simple and easy to use. The driver primary side is equipped with a 10-pin interface connector with the following terminals: •... -
Page 7: Vdc Terminal
2SC0435T Target VDC terminal The driver has one VDC terminal on the interface connector to supply the DC-DC converters for the secondary sides. VDC should be supplied with 15V. It is recommended to connect the VCC and VDC terminals to a common +15V power supply. -

Page 11: Active Clamping (Aclx)
Basic active clamping topologies implement a single feedback path from the IGBT’s collector through transient voltage suppressor devices (TVS) to the IGBT gate. The 2SC0435T supports CONCEPT’s advanced active clamping, where the feedback is also provided to the driver’s secondary side at pin ACLx: as soon as the voltage on the right side of the 20Ω... -
Page 12: How Do 2Sc0435T Scale-2 Drivers Work In Detail
The turn-off voltage is set to 0V. This MOSFET mode is activated by connecting the secondary-side terminals COMx and VEx. If 2SC0435T drivers are to be used in the MOSFET mode, please consult CONCEPT’s technical support service. -
Page 13: Vce Monitoring / Short-Circuit Protection
Overcurrent protection has a lower timing priority and is recommended to be realized within the +Vdc host controller. In order to ensure that the 2SC0435T can be applied as universally as possible, the response Collector/Drain time capacitor C is not integrated in the driver, Voltage but must be connected externally. -
