Alpha & Omega Semiconductor (AOS) announced a family of low capacitance diode arrays, designed and optimized to protect voltage sensitive electronics from high transient conditions and electrostatic discharge (ESD) in the next generation of portable handheld devices.

 

According to Alpha & Omega, this product family comprises four new products that leverage the company’s proprietary Transient Voltage Protection technology that utilizes Trench Vertical Structure for device and process applications.

 

Company officials explained that the AOZ8211 and AOZ8201 produces are single diode solutions that protect one line. They are housed in small footprint packages (1.0 x 0.6 x 0.4 mm for AOZ8211 and 1.6 x 0.8 x 0.6 mm for AOZ8201.

 

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). Officials pointed out that these small packages are ideal for portable devices such as cell phones, PDA smartphones and personal navigation devices where space is at a premium.

 

Also, all four 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.

 

Expressing his company’s pleasure at market acceptance of their low capacitance diode array products, Wayne Eng, director of TVS marketing at AOS, commented in a press release, “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.”

 

AOS is a fabless semiconductor company that develops analog power management solutions. AOS offers a wide portfolio of Power MOSFET, Power IC and Transient Voltage Suppressor products that incorporate advances in device design, silicon and packaging technologies.
