USB50803C(-A) – USB50824C(-A) Available Bidirectional Low Capacitance TVS Array DESCRIPTION This USB50803C(-A) – USB50824C(-A) family of Transient Voltage Suppressor (TVS) arrays comes in an SO-8 package and can provide 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 secondary effects of lightning. Using the schematic on the last 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 connections may be switched in polarity since the electrical features are the same in each anti-parallel (opposite facing) leg when the pins are tied together in this manner for bidirectional protection. Th e device with an “-A” suffix is opposite in polarity for each pin-to-pin leg (see schematics). This provides no functional difference for bidirectional TVS protection with the noted pins tied together as described above. But the difference is significant if each leg is being used separately for unidirectional applications. 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 such as TTL, CMOS DRAM’s, SRAM’s, HCMOS, HSIC microprocessors, Universal Serial Bus (USB) and I/O transceivers. FEATURES Provides electrically isolated protection for up to 2 bidirectional lines . Surge protection per IEC 61000-4-2 and IEC 61000-4-4. UL 94V-0 flammability classification. Ultra low capacitance; 3 pF per line pair. • • Ultra low leakage current. RoHS compliant versions available.
