NCP4810 X2 Capacitors Discharger The NCP4810 is a HV switch suitable for implementation of the X2 capacitor discharge function in applications with extremely low standby consumption requirements. It contains two high voltage MOSFETs with 700 V peak capabilities that can be connected directly to AC line voltage. Implementing this IC helps to design optimized www.onsemi.com EMI filter with appropriate X2 capacitor and reduced EMI coil volume and losses.
