USB50803C-Ae3/TR13中文资料TVS Array数据手册Microchip规格书

描述 Description

This Transient Voltage Suppressor (TVS) array is packaged in an SO-8 configuration giving protection to 2 Bidirectional data or interface lines. It is designed for use in applications where very low capacitance protection is required at the board level from voltage transients caused by electrostatic discharge (ESD) as defined in IEC 61000-4-2, electrical fast transients (EFT) per IEC 61000-4-4 and effects of secondary lightning. It is also available with either Tin-Lead plated terminations or as RoHS Compliant with annealed matte-Tin finish by adding an “e3” suffix to the part number*.Using the schematic on the second page, pins 1 & 2 are tied together for the first protected line, and pins 7 & 8 are tied together to ground. The same would occur for a second protected line where pins 3 & 4 tied together and pins 5 & 6 tied together to the ground. These may also be switched in polarity connections since the electrical features are the same in each antiparallel (opposite facing) leg when the pins are tied together in this manner for bidirectional protection. This device with an “A” suffix is opposite in polarity for each pin-to-pin leg to the USB50803C series (see schematic). This provides no functional difference for bidirectional TVS protection with the noted pins tied together as described above. These TVS arrays have a peak power rating of 500 watts for an 8/20 ?sec pulse. This array is suitable for protection of sensitive circuitry consisting of TTL, CMOS DRAM’s, SRAM’s, HCMOS, HSIC microprocessors, UNIVERSAL SERIAL BUS (USB) and I/O transceivers. The USB508XXC product provides board level protection from static electricity and other induced voltage surges that can damage or upset sensitive circuitry.
