Alpha & Omega Semiconductor, Inc. (AOS) announced a family of Low Capacitance Diode Arrays designed and optimized to protect voltage sensitive electronics from high transient conditions and ESD in the next generation of portable handheld devices. The product family comprises four new products: AOZ8201, AOZ8211, AOZ8204 and AOZ8205 that leverage the company’s proprietary [TVS]2 TM (Transient Voltage Protection utilizing Trench Vertical Structure) device and process technology.
The new products are rated to provide ESD protection of ±30kV for contact and air discharge, and offer a low device channel clamping voltage of 6.9V maximum at 15A peak pulse current. Compared to competing devices, the [TVS]2 TM products feature 40% higher ESD ratings and 50% lower clamping voltage, providing the maximum level of protection. Additionally, the [TVS] 2 TM family offers a very low capacitance rating (15pF typ.) resulting in the highest level of signal integrity in dynamic signal applications.
“We are pleased with the market acceptance of our low capacitance diode array products,” said Wayne Eng, Director of TVS Marketing at AOS. “By delivering low channel capacitance, low clamping voltage and a high ESD rating in a small footprint, these new products improve overall system reliability and user experience for next-generation portable handheld devices.”
The AOZ8211 and AOZ8201 are single diode solutions that protect one line. They are housed in small footprint packages with the AOZ8211 available in SOD923 (1.0 x 0.6 x 0.4 mm) and AOZ8201 available in SOD523 (1.6 x 0.8 x 0.6 mm). The AOZ8204 and AOZ8205 are four and five channel low capacitance diode arrays, respectively, housed in the SC-89 package (1.6 x 1.6 x 0.6 mm). These small packages are ideal for portable devices such as cell phones, PDA smart phones and personal navigation devices where PCB space is a premium.
