Preliminary Data Sheet
IXC Series
VAK =
450 V
IA(P) = 2 - 60 mA
RDYN = 9 - 900 k
The IXYS IXC series of high voltage
current regulators consists of non-
switchable, 2-terminal, AC and DC
current regulators.
Fig. 1. Current Regulator Output
Characteristics
Non-switchable regulators
This is a family of extremely stable,
high voltage current regulators with
the typical output characteristic shown
in Figure 1. The temperature stability
is based on a threshold compensation
technique and uses IXYS' most
recently developed high voltage
process. The complete family will be
capable of providing other
intermediate current levels which can
be programmed on-chip during the
manufacturing phase.
Specific applications are current
sourcing in PABX applications,
telephone line terminations, surge
protection and voltage supply
protection. Two devices in a back-to-
back configuration will give
bidirectional operation. Specific
bidirectional applications would be
series surge protection and soft start-
up applications from AC mains.
AC non-switchable regulators
This family consists of two DC current
regulators connected internally in
series to regulate the current to a
specified value in both directions. Its
output characteristics in quadrants 1
and 3 are the same as shown in Figure
1 so that the current regulation is also
the same in both directions. Parts are
only available in the TO-220 package.
