Thomas Road Scottsdale, AZ 85251 Tel: (480) 941-6300 Fax: (480) 947-1503 USB50403 thru USB50424 DESCRIPTION (500 watt) This 4 pin 1 line unidirectional ULTRA LOW CAPACITANCE array is designed for use in applications requiring board level protection from voltage transients caused by electrostatic discharge (ESD) as defined by IEC 1000-4-2, electrical fast transients (EFT) per IEC 1000-4-4 and effects of secondary lightning. These arrays are used to protect 1 discrete line utilizing pins (1,4 signal and 2,3 ground). The S0T-143 product provides board level protection from static electricity and other induced voltage surges that can damage sensitive circuitry. These TRANSIENT VOLTAGE SUPPRESSOR (TVS) Diode Arrays protect 3.3 Volt components such as DRAM’s, SRAM’s, CMOS, HCMOS, HSIC, and low voltage interfaces up to 24Volts. TVSarray ™ Series FEATURES • • • • • Protects 3.3 up through 24V Components Protects 1 line bidirectional Provides electrically isolated protection SOT-143 Packaging ULTRA LOW CAPACITANCE 3 pF MECHANICAL • • • • Molded SOT-143 Surface Mount Weight: .035 grams (approximate) Body Marked with device marking code Pin #1 defined by DOT on top of package MAXIMUM RATINGS • • • • Operating Temperatures: -550C to +1500C Storage Temperature: -550C to +1500C Peak Pulse Power: 500 Watts (8/20 µ sec, Figure 1) Pulse Repetition Rate:
