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 45 x 34.3mm and an insertion height of max. 16mm. It allows even the most restricted insertion spaces
to be efficiently used.

Preliminary
Emitter terminal (VEx)
The emitter terminal must be connected to the IGBT auxiliary emitter with the circuit shown in Fig. 6.
Active clamping (ACLx)
Active clamping is a technique designed to partially turn on the power semiconductor as soon as the collector-
emitter (drain-source) voltage exceeds a predefined threshold. The power semiconductor is then kept in linear
operation.
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 2SC0108T2Dx-xx 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 resistor (see Fig. 6) exceeds about 1.3V, the turn-off MOSFET is
progressively switched off in order to improve the effectiveness of the active clamping and to reduce the
losses in the TVS. The turn-off MOSFET is completely off when the voltage on the right side of the 20Ω
resistors (see Fig. 6) approaches 20V (measured to COMx).
It is recommended to use the circuit shown in Fig. 6. The following parameters must be adapted to the
application:
• TVS D2x, D3x. It is recommended to use:
- Six 80V TVS with 600V IGBTs with DC link voltages up to 430V. Good clamping results can be
obtained with six unidirectional TVS P6SMBJ70A from Semikron or with six unidirectional TVS
SMBJ70A-E3 from Vishay.
- Six 150V TVS with 1200V IGBTs with DC link voltages up to 800V. Good clamping results can be
obtained with six unidirectional TVS SMBJ130A-E3 from Vishay or six unidirectional TVS SMBJ130A-
TR from ST. Note that 1200V IGBTs can only be driven with the 2SC0108T2Dx-12 or the
2SC0108T2Dx-07 if the maximum operating voltage under absolute maximum ratings (see driver
data sheet /3/) is not exceeded (e.g. specific 3-level topologies such as NPC2).
The use of bidirectional TVS is not required.
Note that it is possible to modify the number of TVS in a chain. The active clamping efficiency can be
improved by increasing the number of TVS used in a chain if the total threshold voltage remains at the
same value. Note also that the active clamping efficiency is highly dependent on the type of TVS used
(e.g. manufacturer).
• Raclx and Caclx: These parameters allow the effectiveness of the active clamping as well as the losses in
the TVS and the IGBT to be optimized. It is recommended to determine the value with measurements
in the application. Typical values are: Raclx=0…150Ω and Raclx*Caclx=100ns…500ns. Raclx=0Ω is
recommended to improve the effectiveness of active clamping.
• D4x: it is recommended to use TVS diodes with a stand-off voltage of 33V (peak current >15A
depending on the application) as SMBJ33A from Vishay, ST, Fairchild or P6SMBJ33A from Diotec.
• D6x: it is recommended to use TVS diodes with stand-off voltages >60V (peak current >1A) as
SMAJ70A from Vishay, ST, Fairchild or P4SMAJ70A from Diotec).
Please note that the 20Ω resistor as well as diodes D4x and D6x must not be omitted if advanced active
clamping is used. If advanced active clamping is not used, the 20Ω resistor as well as diodes D4x and D6x can
be omitted.
