Three-In-One Protection Comes In A Miniature Package

The SPUSB1 upstream USB 1.1 port protection network combines ESD protection, EMI/RFI filtering and termination into an ultra small SC70 six-lead package. By upgrading to the SPU- SB1, manufacturers of upstream USB devices such as PDAs, digital cameras, scanners and hubs are expected to benefit from lower field failures as well as board space reduction, and assembly and inventory cost savings. The company claims the SPUSB1 replaces a minimum of 10 typically larger and more expensive “discrete” devices now required for the functions it performs in one integrated package. It replaces components used to protect upstream circuit elements such as USB controllers. This series gives designers a choice of 12_, 22_ or 33_ series resistance values tailored to match the USB controller resistance and cable impedance. The SPUSB1 generates 30 kV of ESD protection for all data lines, D+, D- and Vbus, as tested under the MIL-STD-883D specification for Human Body Model. In addition, the device offers 15 kV direct discharge protection per IEC 61000-4-2. Available in tape-and-reel packaging, pricing for the SPUSB1AJT, SPUSB1BJT and SPUSB1CJT models are $0.28 each/10,000. LITTELFUSE, Des Plaines, IL. (800) 999-9445.
