2SC0535T
Dual-Channel SCALE-2 Driver Core for 3.3 kV IGBTs
The 2SC0535T2 SCALE-2 dual-driver core combines compactness with broad applicability and cost efficiency. It is designed for high-reliability industrial and traction and drives all usual high-voltage IGBT modules up to 3300 V. Its embedded paralleling capability allows simple inverter design at higher power ratings. Multi-level topologies with 1700 V IGBTs with higher isolation requirements can also be easily supported.
Advantages of the Technology
The 2SC0535T is the most compact driver core in its voltage and power range, featuring a footprint of only 76.5 x 59.2 mm and an insertion height of 26 mm. The SCALE-2 chipset reduces the component count by up to 80% compared to conventional solutions, thus significantly increasing reliability and reducing costs. The 2SC0535T combines a complete two-channel driver core with all components required for driving, such as short-circuit protection, Advanced Active Clamping, an isolated DC/DC converter as well as supply voltage monitoring. Each of the two output channels is electrically-isolated from the primary side and the other secondary channel. An output current of 35 A and 5 W drive power is available per channel, making the 2SC0535T a suitable choice for both high-power modules and parallel-connected IGBT modules. In dedicated IGBT mode, the driver provides a gate voltage swing of +15 V / –10V. The turn-on voltage is regulated to maintain a stable 15 V regardless of the output power level. Moreover, the temperature range has been widened to cover low temperature applications down to -55 °C. Excellent EMC performance allows safe and reliable operation in even harsh industrial conditions. The 2SC0535T driver has a creepage path of 44 mm and is suited for high-voltage IGBTs with blocking voltages up to 3.3 kV. The driver is UL-compliant and features clearance and creepage distances that enable it to meet pollution degree 2 and overvoltage category 2 according to EN-50178 and EN-50124. Therefore, the driver is an excellent choice for all traction and industrial applications. The 100%-tested, partial discharge-free transformer design guarantees safe operation over the expected lifetime.
Driving Parallel-Connected IGBTs
The driver allows direct parallel connection of any number of IGBT modules with individual drivers. This new, pioneering concept makes it practical for the first time to build a converter series with discrete modules as well as parallel-connected IGBTs without any additional development effort.

Power Integrations offers highly integrated IGBT drivers. Based on decades of experience, ASICs have been developed for the driver and monitoring functions, which together with the inductive transformers form the core of the drivers. Extensive application design support is offered.
Highly integrated driver components: cheaper than discrete in-house development
MOSFETs and IGBTs are convenient to drive with low power, unlike bipolar power semiconductors. However, high gate capacitances must be recharged and, in the case of stacked IGBTs for HVDC (high-voltage DC transmission), large potential differences must also be bridged. In addition, there are protection functions for the power semiconductors and a negative bias voltage for IGBTs to be blocked so that they cannot switch through and fail as a result of transients in bridge circuits.
In view of the high voltages, some know-how is required here. For example, special regulations on insulation clearances, clearances and creepage distances, and partial discharge resistance must be observed, and these must also be checked with expensive measuring equipment. Likewise, the degradation of the board substrate and the migration of metal ions in it must be taken into account, which can otherwise lead to premature short circuits and total failures.
Instead of launching costly in-house developments, it makes sense here to use proven, safe driver modules designed using in-house developed, monolithic highly integrated semiconductor components as well as proprietary planar transformers, such as those offered by Power Integrations under the name SCALE (which stands for Scaleable, Compact, All-purpose, Low-cost and Easy-to-use). Power Integrations, previously CONCEPT, has been developing IGBT driver solutions for over 30 years and therefore has unrivaled experience with this topic.
The SCALE devices are driven with standard logic levels from 3.3 to 15 V and are very economical in the IGBT field: they are cheaper and more reliable than conventional discrete circuit designs, especially when it comes to driving high-voltage IGBTs. Thus HY-LINE Power Components offers you everything around inverters and high performance DC/DC converters from one source.
Power Integrations offers both general modules, the SCALE Driver Cores, and modules adapted to specific IGBT modules, the SCALE Plug-and-Play Drivers. In addition, there are the monolithically integrated SCALE iDriver chips.
