The S
M03 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, COMS, HCOMS, HSIC, and low volt.
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.
