2SC0635T2A0-45 Preliminary Datasheet
Dual-Channel Cost-Effective SCALE™-2 IGBT Dr iver Core for 4500V IGBTs
Abstract
The SCALE™-2 dual-driver core 2SC0635T2A0-45 combines unrivalled compactness with broad applicability.
The driver is designed for universal a pplications requiri ng high reliability. The 2SC0635T2A0-45 drives all usual
high-power IGBT modules up to 4500V. Its embedded paralleling capability allows easy inverter design
covering higher power ratings. Multi-level topologies involving 1700V or 3300V IGBTs with higher isolation
requirements can also be easily supported by 2SC0635T2A0-45.
The 2SC0635T2A0-45 combines a complete two-channel driver core with all components req uired for driving,
such as an isolated DC/DC converter, short-circuit protection, Advanced Active Clamping as well as supply
voltage monitor ing. E ach o f the t wo outp ut channe ls is elect rically isolated from th e primary side a nd from the
other seconda ry channel.
An output current of 35A and 6W drive power is available per channel, making the 2SC0635T2A0-45 an ideal
driver platform for universal use in medium and high-power applications. 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.
Its outstanding EMC allows safe and re liable operation even in hard industrial applicat ions.

Output voltage swing
The output voltage swing consists of two distinct se gments. First, there is the tu rn-on voltag e VGHx between
pins GHx and VEx. VGHx is regulated and maintained at a constant level for all output power values and
frequencies.
The seco nd segm ent o f the output voltag e swing i s the turn-off vo ltag e VGLx. VGLx is measured between pins
GLx and VEx. It is a negative voltage. It changes with the output power to accommodate the inevitable
voltage drop across the internal DC/DC converter.

Footnot es to the K ey D a ta
1) The maximum peak gate current refers to the highest current level occurring during the product
lifetime. It is an absolute value and does a lso apply for short pu lses.
2) The average supply input current is limited for thermal reasons. Higher values than specified by the
absolute maximum rating are permissible (e.g. during power supply start up) if the average remains
below the given value, provided the average is taken over a time period which is shorter than the
thermal time constants of the driver in the application.
3) There is no means of actively controlling or limiting the input current in the driver. In the case of
start-up with very high blocking capacitor values, or in case of short circuit at the output, the supply
input current has to be limi ted externall y.
4) The maximum output power must not be exceeded at any time during operation. The absolute
maximum rating must also be observed for time periods shorter than the thermal time constants of
the driver in the application.
5) An extended output power range is specified in the output power section for ambient temperatures
limited from 0°C to 70°C.
6) The delay time is measured between 50% of the input signal and 10% voltage swing of the
corresponding output. The de lay time is independent on the o utput l oadin g.
7) Output rise and fall ti mes are meas ured betwee n 10% and 90% of the nomi nal output swing w ith an
output load of 4.7Ω and 270nF. The values are given for the driver side of the gate resistors. The time
constant of the output load in conjunction wit h the present ga te resistors lea ds to an additio nal delay
at the load side of the gate resistors.
8) External blocking capacitors should be placed between the VISOx and VEx as well as the VEx and
COMx terminals. Refer to “2SC0635T Description & Application Manual” (paragraph “DC/DC output
(VISOx), emitter (VEx) and COMx terminals)” for recommendations. Ceramic capacitors are
recommended.
9) The minimum response time is valid for the circuit given in the description and application manual
(Fig. 7) wi th the values of table 1.
10) The blocking time sets a minimum time span between the end of any secondary-side fault state and
the start of normal operation (remove fault from pin SOx). The value of the blocking time can be
adjusted at pin TB.
11) Undervoltage monitoring of the primary-side supply voltage (VCC to GND). If the voltage drops below
this limit, a fault is transmitted to both SOx outputs and the power semiconductors are switched off.
12) Under volta ge m onit oring of t he sec onda ry-sid e s uppl y voltag e (V ISOx t o V Ex and V Ex to C OMx, which
correspond to the approximate turn-on and turn-off gate-emitter voltages). If the corresponding
voltage drops below this limit, a fault is transmitted to the corr esponding SOx o utput and the IGBT is
switched off after the corresponding delays. Refer to “2SC0 635 T Description & Ap plicat ion Manual” for
more details.
13) Transmission delay of fault state from the secondary side to the corresponding primary-side status
output.
14) HiPot testing (= dielectric testing) must generally be restricted to suitable components. This gate
driver is suited for HiPot te sting. Nevertheless, it is st rongly recommended to limi t the testing time to
1s slots. Excessive HiPot testing at voltages much higher than 3182VAC(eff) may lead to insulation
degradation. No degradation has been observed over 1min. testing at 10.2kVAC(eff). Every production
sample shipped to customers has undergone 100% testing at the given value for 1s.

15) Partial discharge measurement is performed in accordance with IEC 60270 and isolation coordination
specified in IEC 60664-1. The partial discharge extinction voltage between primary and either
secondary side is coordinated for basic isolation to IEC 60664-1.
16) Jitter measurements are performed with input signals INx switching between 0V and 15V referred to
GND, with a corresponding rise time and fall time of 6ns.
17) The minimum operating temperature is limited to -40°C for the first series. This will be extended
to -55°C upon co mpl et ion o f the ongoi ng qua lifi ca tio n prog ra m.
18) The VCE–monitoring threshold value can be reduced with an external resistor. Refer to “2SC0635T
Description & Application Manual”.
19) The turn-off event of the IGBT after a secondary-side fault (IGBT short circuit or undervoltage
monitoring) can be additionally d elayed wit h an exte rnal cap acitor. Re fer to “2S C0635T Des criptio n &
Application Manual”.
