POWER INTEGRATIONS CAP019DG X capacitor discharge IC
The CAPZero™ is an energy-efficient, automatic X capacitor discharge IC designed for use in AC-DC converters, appliances, and other systems requiring ultra-low no-load power consumption. When AC voltage is applied, it blocks current flow through the X capacitor safety discharge resistors, significantly reducing power loss to less than 5mW at 230VAC. Upon disconnection of AC power, the device automatically discharges the X capacitor via its internal discharge resistors, enabling safe and flexible capacitor selection for optimal EMI filtering and reduced inductor costs without increasing power consumption. The compact, two-terminal design meets safety standards for use before or after system fuses, with robust features including large creepage clearance (over 4mm), high surge immunity, and internal MOSFETs rated at 1000V BVDSS. Suitable for use with X capacitance greater than 10nF, up to 5μF total capacitance, and series resistance around 150kΩ, the CAPZero simplifies system design, particularly for products targeting EuP Lot 6 compliance and low standby power.
