This 3 pin TRANSIENT VOLTAGE SUPPRESSOR offers 2 unidirectional or 1 bidirectional protection at the board level from voltage transients caused by electrostatic discharge (ESD) as defined by IEC 61000-4-2, electrical fast transients (EFT) per IEC 61000-4-4.Unidirectional protection can be accomplished by connecting the Input/Output lines to pins 1 and 2 and pin 3 to common ground. In a bidirectional configuration pin 1 or pin 2 is connected to common or ground. Pin 3 is not connected.This 3 pin TRANSIENT VOLTAGE SUPPRESSOR offers 2 unidirectional or 1 bidirectional protection at the board level from voltage transients caused by electrostatic discharge (ESD) as defined by IEC 61000-4-2, electrical fast transients (EFT) per IEC 61000-4-4.

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. RoHS Compliant devices also available be adding an e3 suffix.
