New Line of Filters Targets Portable Applications

The AOZ803x family of multi-line EMI filters from Alpha & Omega Semiconductor has been crafted to provide EMI/ESD protection in next-generation, portable handheld devices. These filters were designed using the company’s proprietary TVS²™ technology—i.e., Transient Voltage Suppression utilizing Trench Vertical Structures. This filter family features three products: the AOZ8030, the AOZ8033, and the AOZ8035, which come with eight, four, and six lines, respectively. Filter performance is rated at -35-dB attenuation from 800 MHz to 3.0 GHz over the full operating range of battery-powered LCD displays. Low channel clamping voltage of 10 V maximum at 12 A peak pulse current protects sensitive IC components. All devices are rated to provide ESD protection of ±kV for both contact and air discharge. The AOZ803x products come in small footprint 0.4-mm pitch DFN packages for applications where PCB space is at a premium.
