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.
SM03
thru
SM36
TVSarray™ Series
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.
