IXCP10M90S Current Regulator 100mA TO-220-3

IXCP10M90S Current Regulator 100mA TO-220-3

The IXCP10M90S is a high-voltage, switchable current-regulator packaged in a TO-220-3 (TO-220AB) case. It is designed to act as an on/off current source rather than a simple resistor, providing a controlled plateau current over a wide VAK range. The device is tailored for low-current, high-voltage roles where a steady current is required while the voltage across the device can swing to hundreds of volts.

Internally the device exhibits a characteristic internal resistance that sets its bias behavior and a plateau current that can be shaped by an external series resistor. Thermal design is important: the TO-220 package allows mounting to a heatsink and the device supports significant case dissipation when properly cooled, enabling continuous operation in demanding high-voltage circuits.

Control of the regulator is achieved through the gate terminal (G), which enables on/off behavior and modulation of the plateau current. The IXCP10M90S is therefore useful wherever a reliable, limited current is needed across large voltage swings provided designers follow the datasheet’s mechanical, thermal and safe-operating-area guidelines.

Features:

• 40 W continuous dissipation at specified case temperature.
• JEDEC standard packages (TO-220 and TO-252) for easy mounting and cooling.
• On/Off switchable current-source operation via gate terminal.
• High blocking voltage capability (900 V VAK rating).
• Typical internal RAK ~58 kΩ for predictable biasing behavior.
