www.DataSheet4U.com High Voltage Current Regulators Preliminary Data Sheet The IXYS IXC series of high voltage current regulators consists of nonswitchable, 2-terminal, AC and DC current regulators. IXC Series VAK = 450 V IA(P) = 2 - 60 mA RDYN = 9 - 900 kΩ TO-220 AB (IXCP) 4 4 1 3 12 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. Current Regulator Nomenclature Parts can be ordered by using the following nomenclature: TO-252 AA (IXCY) 3 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-toback configuration will give bidirectional operation. Specific bidirectional applications would be series surge protection and soft startup applications from AC mains.

The device is again connected in series with the lead (Fig. 5) and would normally operate at a current level lower than the plateau (Fig. 6a). Any incoming voltage surge (Fig. 6b) less than the breakdown voltage of the regulator will be clamped by the IXCP regulator to voltage less than the plateau current times the effective resistance of the load.
