2SD106AI Data Sheet
2SD106AI Dual SCALE Driver Core
for IGBTs and Power MOSFETs
Description
The SCALE drivers from CONCEPT are
based on a chip set that was developed
specifically for the reliable driving and
safe operation of IGBTs and power
MOSFETs.
The name “SCALE” is an acronym for the most
outstanding properties of the SCALE series of
drivers:
SCALE = Scaleable, Compact, All purpose, Low
cost and Easy to use.
The SCALE driver is a winning project of the
competition organized by “Technology Center
Switzerland 1998”. And ABB Switzerland AG honored the development of the SCALE
driver by distinguishing it as the “best power electronics project in 1998”.

The drivers have a zener diode on each channel for over-voltage protection. When the feed voltage
exceeds 16V, this protection can be subject to thermal overload.
If the specified power consumption is exceeded, this indicates an overload of the DC/DC converter.
It should be noted that these DC/DC converters are not protected against overload.
This should be considered as a recommended value. Please consult the section: “Output power
and self-heating”.
Under-voltage monitoring for protecting the power semiconductors. The voltage refers to the local
supply voltage of each individual drive channel. However, this corresponds approximately to the
voltage at VDC with respect to GND.
The input levels must never exceed the limits of the supply voltage (i.e. between GND and VDD),
otherwise latch-up of the integrated circuits LDI 00I can occur. Particular care must be taken when
driving via cables or longer leads.
The gate current must be limited to its maximum value by a gate resistor.
At a load of 39nF in series with 5.6 : (typical load of a 1200V/100A IGBT).
Maximum continuous or repeatedly-applied DC voltage between all inputs and all outputs.
However, types that have been measured and selected for higher partial-discharge voltages (e.g.
for 1700V IGBT modules) are also available.
This specification guarantees that the drive information will be transferred reliably even at a high
DC-link voltage and fastest switching operations.
The application-specific self-heating of the drivers - specially at high load - must be taken into
account.
The test voltage of 4000 Vac(rms)/50Hz may be applied only once during a minute. It should be
noted that with this (strictly speaking obsolete) test method, some (minor) damage occurs to the
isolation layers due to the partial discharge. Consequently, this test is not performed at CONCEPT
as a series test. In the case of repeated isolation tests (e.g. module test, equipment test, system
test) the subsequent tests should be performed with a lower test voltage: the test voltage is
reduced by 400V for each additional test. The more modern if more elaborate partial-discharge
measurement is better suited than such test methods as it is almost entirely non-destructive.
The typical blocking time after an error is 1 second. If required, versions with other blocking times
may also be supplied.

Application Hints
IMPORTANT INFORMATION
This data sheet contains only product-specific data. All data that apply to
the whole type series of SCALE drivers is given in the document entitled:
“Description and Application Manual for SCALE Drivers”. In particular, this
manual contains a detailed description of the concept of the SCALE
drivers, a description of the function of all terminal pins as well as other
important application hints.
Overview and application
The SCALE driver 2SD106AI is a two channel-driver for power MOSFETs and IGBTs.
Its compact mechanical dimensions and simple electrical interface make this driver
suitable for almost all conceivable applications. When used as a half-bridge driver, the
2SD106AI can directly generate any dead times that may be required.
Output power and self-heating
The specified output power of the driver totals 2W (1W per channel). This typically
suffices to drive a 100A/1200V six-pack IGBT module with 25kHz. In the case of a drive
power of 2W, the typical input power of the driver is about 2.33W; the losses due to
the driver total about 0.33W. Because CONCEPT cannot predict how the drivers will be
incorporated in the user’s application, no binding recommended value for self-heating
and thus for the maximum useful output power at high ambient temperatures can be
made. It is consequently recommended to check the self-heating of the system,
especially when it is used at higher temperatures.
For the calculation of the exact output power, reference should be made to Application
Note AN-9701 “IGBT drivers correctly calculated” on www.igbt-driver.com/go/app-note.

To correspond more
effectively to the
Fig. 4 Collector-sense circuit principle
turn-on characteristic
of the IGBTs, the
SCALE drivers do not use a static reference voltage to compare the voltage at the
collector. Instead, the reference is used as shown in Fig. 5.

Notes on Table 1
The values for “Vth1” and “Vth2” are listed in Table 1 as a function of the reference
resistance Rth.
The value in the “Vth1” column corresponds to the voltage threshold after the response
time has elapsed.
The value in the “Vth2” column corresponds to the voltage which is set up statically
across the resistor Rth. This static value is typically reached after between 10 and 15µs.

The value in the “VCE(off)” column corresponds to the collector-emitter voltage value at
which the protection function is activated when the external circuit is used as shown in
