| SM03 8700 E. Thomas Road Scottsdale, AZ 85251 Tel: (480) 941-6300 Fax: (480) 947-1503 thru SM36 TVSarrayTM Series TM DESCRIPTION (500 watt) This 3 pin Transient Voltage Suppresor offers 2 unidirectional or 1 bidirectional protection 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. Unidirectional protection, can be accomplished by connecting the Input/Output lines to pins 1 and 2 and pin 3 to common or ground. In a bidirectional configuration pin 1 or pin 2 is connected to the Input/Output line while the opposite pin is connected to common or ground. Pin 3 is not connected. The SM03 thru SM36 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 36 Volts. Because of the physical size, weight and protection capabilities, this product is ideal for use in but not limited to miniaturized electronic equipment such as hand-held instruments, computers, computer peripherals and cell phones.
