Thomas Road Scottsdale, AZ 85251 Tel: (480) 941-6300 Fax: (480) 947-1503 USB50403C thru USB50424C TVSarray TM Series DESCRIPTION (500 watt) This 4 pin 1 line bidirectional 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. 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 sec, Figure 1) Pulse Repetition Rate: <.01% PACKAGING * * Tape & Reel EIA Standard 481-1-A 7 inch reel 3,000 pieces ELECTRICAL CHARACTERISTICS @ 250C Unless otherwise specified STAND OFF VOLTAGE VWM VOLTS MAX USB50403C USB50405C USB50412C USB50415C USB50424C 53 55 512 515 524 3.3 5.0 12.0 15.0 24.0 BREAKDOWN VOLTAGE VBR @1 mA VOLTS MIN 4 6.0 13.3 16.7 26.7 CLAMPING VOLTAGE VC @ 1 Amp (FIGURE 2) VOLTS MAX 8 10.8 19 25 44 CLAMPING VOLTAGE VC @ 5 Amp (FIGURE 2) VOLTS MAX 11 13 26 32 57 STAND OFF CURRENT ID @ VWM A MAX 200 40 1 1 1 CAPACITANCE (f=1 MHz) @0V C pF MAX 3 3 3 3 3 TEMPERATURE COEFFICIENT OF VBR aVBR mV/C MAX -5 1 18 11 28 PART NUMBER DEVICE MARKING NOTE: Transient Voltage Suppression (TVS) product is normally selected based on its stand off Voltage VWM. Product selected voltage should be equal to or greater than the continuous peak operating voltage of the circuit to be protected.
