SPUSB1AJT

Silicon Protection Circuits Upstream USB Port Terminator with ESD Suppression & EMI Filtering SPUSB1 Series NEW The Littelfuse SPUSB1 Series is a multifunctional USB port protection network designed to provide ESD protection, EMI/RFI filtering and line termination for a single USB 1.1 port. The SPUSB1 can replace a minimum of ten typically larger “discrete” devices resulting in inventory and placement cost savings. The SPUSB1 Series combines Transient Voltage Suppression (TVS) avalanche diodes, EMI/RFI filtering components (R1 and C1), and a 1.5kΩ termination resistor (R2). The filtering components are included to satisfy recommendations in the USB 1.1 specification, and the 1.5kΩ resistor (R2) is included as a pull-up resistor to VBUS. The SPUSB1 Series can be used for termination and protection of “upstream” USB devices such as PDAs, digital cameras, scanners and hubs which are often at risk from transient voltage surges and electromagnetic interference from both intern...
