CAPZero ICs Automatically and Safely Discharge X Capacitors, Eliminating Losses in Power-Supply EMI Filters

Power Integrations today launched CAPZero™, a family of innovative, two-terminal, automatic X capacitor discharge ICs that eliminate power losses while allowing power supplies to comply with safety standards. CAPZero acts as a smart high-voltage switch when placed in series with discharge resistors. When AC voltage is applied, CAPZero blocks current flow in the X capacitor safety discharge resistors, reducing the power wasted in these components to zero at 230 VAC.
