Six-pa ck SCALE Driver 6SD106EI
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 M OSFETs.
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 di stinguishing it as the “best po wer electronics project in 1998”.

Footnotes to the key data
1) 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.
2) If the specified power consumption is exceeded, this indicates an overload of the DC/DC converte r.
It should be noted that these DC/DC converters are not protected against overload.
3) This should be considered as a recommended value. Please consult the section: “Output power
and self-heating”.
4) Under-voltage monit oring for protecting the p ower semiconductors. T he voltage re fers to the local
supply voltage of each individual drive channel. However, this corresponds approximately to the
voltage at VDC with respect to GND.
5) The input levels must never exceed the limits of the supply voltage (i.e. between GND and VDD),
otherwise latch -up of t he int egra ted circuits LDI 0 0I can oc cur . Pa rt icul ar car e m u st be ta ken whe n
driving via cables or l onge r leads.
6) The gate current must be limited to its maximum value by a gate resistor.
7) At a load of 39nF in series with 5.6 ( typical load of a 1200V/100A IGBT).
8) Maximum continuous or repeatedly-applied DC voltage or peak value of the repeatedly-applied AC
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 (see Note
11).
9) This specification guarantees that the drive information will be transferred reliably even at a high
DC-link voltage and fastest switching operations.
10) The application-specific self-heating of the drivers - specially at high load - must be taken into
account.
11) 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 be tter suite d than such test methods as it is almost entirely non-destructive.
12) The typi cal blocking time after an error is 1 second. If required, versions with othe r blocking times
may also be supplied.

Application Hints
IMPORTANT INFORM AT ION
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:
“Desc ription an d A pplica tion M anu al for S CAL E Dri vers” . In particu lar, th is
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 applic a tion
The SCA L E driver 6SD106EI i s a six-pack driver for power MOSFETs and IGBTs.
The terminal pins of the 6SD106EI driver are arranged so that the layout can be kept
very simple and the logic signal flow (input signal ⇒ drive circuit ⇒ power transistors)
is maintained. A distance of 12.7mm is observed between the drive signal and the
power potential!
Collector sense and d imensioning of Rth
The 6SD106EI six-
pack driver has a
collector-sense circuit
to protect the power
semiconductors. It is
shown in Fig. 4
Its basic operating
mode can be ob-
tained from the
brochure entitled:
“Description and

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 R th.
The value in the “Vth1” column cor-
responds to the voltage threshold after
the resp onse time h as elap sed.
The value in the “Vth2” column cor-
responds to the voltage which is set u p
statically across the resistor Rth. This
static value is typically reached after
betw een 10 and 15 µs.
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 Fig. 4 with
one or two Dm diodes of type 1N4007
connected in series.

Output p ower and sel f -heating
The specified output power of the driver totals 6W (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 6W, the typical input power of the driver is about 7W; the losses due to the
driver total about 1W. 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 cal culated” on www.igbt-driver.com/go/app-note.
