2SC0535T

Cost Efficient SCALE-2 Dual Driver Core for 3.3kV IGBTs

Compact, high-voltage, high-power IGBT driver

Highly integrated SCALE-2 technology

35A gate current and 2 x 4W output power

Short Description

The SCALE-2 dual-driver core 2SC0535T2Ax-33 combines unrivalled compactness with broad applicability and cost efficiency. The driver is designed for industrial and traction applications requiring high reliability. The 2SC0535T2Ax-33 drives all usual high-voltage IGBT modules up to 3300V. The embedded paralleling capability allows easy inverter design covering higher power ratings. Multi-level topologies with 1700V IGBTs with higher requirements on the isolation can also be easily supported by 2SC0535T2Ax-33.

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 59.2mm and an insertion height of 26mm. It allows even the most restricted insertion spaces to be efficiently used. Compared with conventional drivers, the highly integrated SCALE-2 chipset allows about 85% of components to be dispensed with. This advantage is impressively reflected in increased reliability at simultaneously minimized cost.

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 35A and 4W drive power is available per channel, making the 2SC0535T an ideal driver platform for both high-power modules and parallel circuits. In the dedicated IGBT mode, the driver provides a gate voltage swing of +15V/–10V. The turn-on voltage is regulated to maintain a stable 15V regardless of the output power level. Moreover the temperature range has been increased up to -55°C to cover applications requiring lower temperatures.

Its outstanding EMC allows safe and reliable operation in even hard industrial applications. The 2SC0535T driver has a creepage path of 44mm and is suited for high-voltage IGBTs with blocking voltages up to 3.3kV. The driver is UL comliant, clearance – and creepage distances meet pollution degree 2 and overvoltage category 2 according to IEC-60077, IEC60664, EN-50178 and EN-50124. Thus making the device the perfect choice for all traction and industrial applications. The 100% tested, partial discharge free transformer design guarantees safe operation over the expected lifetime of more than 7 Mio. hours.

Driving Parallel-Connected IGBTs

The driver allows direct parallel connection of any number of IGBT modules with individual drivers. This new pioneering concept for simple and reliable parallel connection makes it practical for the first time to set up converter series with discrete modules as well as parallel-connected IGBTs without any additional development effort.
