PRODUCT PREVIEW
DESCRIPTION
TVSarray™ SERIES
DESCRIPTION (300 watt)
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. The SM03 thru
SM36 product provides board level protection from static electricity and other
induced voltage surges that can damage sensitive circuitry.
APPLICATIONS
• EIA-RS232 data rate
19.6kbs
• EIA-RS422 data rate
10Mbs
• EIA-RS423 data rate
100kbs
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.
