Array Designed for Dual USB Port Electrostatic Discharge Protection

With a capacitance of 3 pF per line, the SRV05-4 array has been designed for protection against electrostatic discharge (ESD) in applications such as dual USB ports. It is also said to be ideal protection for video graphic cards, 3G cellular handsets, 10/100/1,000Base-T Ethernet circuits and SIMM cards. Rated for 5V applications, the array combines eight low-capacitance steering diodes for up to four individual data or transmission lines, and one TVS diode for the power bus. The array’s small, space-saving SOT-23 6L plastic package minimizes lead inductance, preventing overshoot voltages during high ESD current events. This device meets and exceeds the ESD requirements of IEC 61000-4-2, along with the EFT requirements of IEC 61000-4-4. SPICE model and parameters are available for circuit simulations. Pricing is $0.45 each/10,000. PROTEK DEVICES, Tempe, AZ. (602) 414-5107.
