PIN array
Fig. 2 shows the pin arrays. The input side (primary side) comprises 10 inputs (SKHI 22A / 21A 8 inputs), forming the
interface to the control circuit (see fig.1).
The output side (secondary side) of the hybrid driver shows two symmetrical groups of pins with 4 outputs, each forming
the interface to the power module. All pins are designed for a grid of 2,54 mm.

Persons working with CMOS-devices have to wear a
grounded bracelet. Any synthetic floor coverings must not
be statically chargeable. Even during transportation the
input terminals have to be short-circuited using, for
example, conductive rubber. Worktables have to be
grounded. The same safety requirements apply to
MOSFET- and IGBT-modules!
The connecting leads between hybrid driver and the
power module should be as short as possible, the driver
leads should be twisted.
Any parasitic inductances within the DC-link have to be
minimized. Over-voltages may be absorbed by C- or
RCD-snubbers between the main terminals for PLUS and
MINUS of the power module.
When first operating a newly developed circuit,
SEMIKRON recommends to apply low collector voltage
and load current in the beginning and to increase these
values gradually, observing the turn-off behaviour of the
free-wheeling diode and the turn-off voltage spikes
generated accross the IGBT. An oscillographic control will
be necessary. In addition to that the case temperature of
the module has to be monitored. When the circuit works
correctly under rated operation conditions, short-circuit
testing may be done, starting again with low collector
voltage.
It is important to feed any errors back to the control circuit
and to switch off the device immediately in such events.
Repeated turn-on of the IGBT into a short circuit with a
high frequency may destroy the device.
Mechanical fixing on PCB:
In applications with mechanical vibrations (vehicles)2 do
not use a ty-rap for fixing the driver, but - after soldering
and testing - apply special glue. Recommended types:
CIBA GEIGY XP 5090 + 5091; PACTAN 5011; WACKER
A33 (ivory) or N199 (transparent), applied around the case
edge (forms a concave mould). The housing may not be
pressed on the PCB; do not twist the PCB with the driver
soldered on, otherwise the internal ceramics may crack.
The driver is not suitable for big PCBs.
SEMIKRON offers a printed circuit board (PCB) type
SKPC2006 compatible for mounting a SKHI 21A or
SKHI 22A. This PCB contains the necessary tracks to
connect the external capacitors CCE and resistors RCE,
Ron, Roff (see fig. 1).
The PCB may directly be plugged to SEMITRANS 3-IGBT
modules and be fixed to the heatsink by 3 thread bolts.
Dimensions: L x W x H = 96 x 67 x 1,5 mm.
For further details please contact SEMIKRON.
2.tested acceleration (x; y; z-axis):10-100 Hz: 1,5 g;
shock: 5 g (TÜV according to LES-DB-BN 411002)
