DESCRIPTION (300 and 500 watt)
This 8 pin 4 line Unidirectional or Bidirectional array is designed for use in applications where protection is required at the board level 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 lighting. These arrays are used to protect any combination of 4 lines. The SMDA/B 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 3.0/3.3 Volt components such as DRAM's, SRAM's, CMOS, HCMOS, HSIC, and low voltage interfaces up to 24Volts.
