CAPZero-2 data sheet - .PDF file.

Power Integrations has launched the  CAPZero-2 ICs, the next generation of its CAPZero line of two-terminal, X capacitor discharge ICs. CAPZero-2 ICs increase design flexibility by covering a wide range of applications and output power. 

CAPZero-2 ICs are smart, high-voltage switches that significantly reduce no-load and standby input power consumption. Placed in series with resistors that provide a safe discharge path for a power supply’s X capacitor, CAPZero-2 devices block current flow to the discharge resistors when AC voltage is applied, cutting the power wasted in these components to zero.

When the AC voltage is disconnected, the CAPZero-2 switch automatically and safely discharges the X capacitor by closing the circuit and directing the energy away from the exposed AC plug.

Featuring an expanded X capacitor range from 0.1 µF to 6 µF, a rating of 1kV breakdown voltage which allows for a transient voltage capability of 6 kV, CAPZero-2 ICs withstand severe line surges and swells.

Applications include air-conditioners, home appliances, small appliances, cookers, vacuum cleaners, TVs, desktop and notebook PCs, projectors, workstations, computer monitors, and printers.

Key product features

  • X capacitor range from 0.1 µF to 6 µF
  • Increases design flexibility and speeds time-to-market while reducing the resources required to qualify devices
  • Safety-certified to CB and Nemko requirements so developers do not need to perform a separate capacitive discharge safety test of the power circuit.
  • Withstands severe line surges and swells.

Power Integrations

Power Integrations is the leading supplier of high-voltage integrated circuits used in energy-efficient power conversion. The company’s innovative technology enables compact, energy-efficient power supplies in a wide range of electronic products, in AC-DC, DC-DC and LED lighting applications. Since its introduction in 1998, Power Integrations’ EcoSmartä energy-efficiency technology has saved an estimated $4.5 billion of standby energy waste and prevented millions of tons of CO2 emissions. The company’s Green Room web site provides a wealth of information about “energy vampires” and the issue of standby energy waste, along with a comprehensive guide to energy-efficiency standards around the world. Reflecting the environmental benefits of EcoSmart technology, Power Integrations is included in clean-technology stock indices sponsored by the Cleantech Group (Amex: CTIUS) and Clean Edge (Nasdaq: CELS).
