DESCRIPTION APPEARANCE

This TRANSIENT VOLTAGE SUPPRESSOR (TVS) array is packaged in an SO-8

configuration giving protection to 4 unidirectional or bi-directional data or interface

lines. It is designed for use in applications where protection is required at the board

level from voltage transients caused by electrostatic discharge (ESD) as defined in

IEC 61000-4-2, electrical fast transients (EFT) per IEC 61000-4-4 and effects of

secondary lightning. These TVS arrays have peak pulse power ratings of 300 watts

(SMDA) and 500 watts (SMDB) for an 8/20 µsec pulse. They are suitable for

protection of sensitive circuitry consisting of TTL, CMOS, DRAM’s, SRAM’s,

HCMOS, HSIC and low-voltage interfaces from 3.3 volts to 24 volts

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

Note: Transient Voltage Suppressor (TVS) product is normally selected based on its stand off voltage VWM. Product selected voltage should be equal to or

greater than the continuous peak operating voltage of the circuit to be protected. Part numbers with a C suffix are bi-directional devices.

SYMBOLS & DEFINITIONS

Symbol Definition

VWM Stand Off Voltage: Maximum dc voltage that can be applied over the operating temperature range.

VWM must be selected to be equal or be greater than the operating voltage of the line to be protected.

VBR Minimum Breakdown Voltage: Minimum voltage the device will exhibit at a specified current

VC Clamping Voltage: Maximum clamping voltage across the TVS device when subjected to a given current at a

pulse time of 20 µs.

ID Standby Current: Leakage current at VWM.

C Capacitance: Capacitance of the TVS as defined @ 0 volts at a frequency of 1 MHz and stated in picofarads.
