DESCRIPTION

The SM712 transient voltage suppressor (TVS)

diode is designed for asymmetrical (12V to -7V)

protection in multi-point data transmission standard

RS-485 applications. The SM712 may be used to

protect devices from transient voltages resulting

from electrostatic discharge (ESD), electrical fast

transients (EFT), and lightning.

The SM712 features 400 Watts (tp=8/20μs) of

power handling capability to accommodate the

higher transient voltage levels which may be

expected in extended common mode applications.

This provides higher equipment reliability and

eliminates the “guess work” required when using

zener diodes that are not rated to handle such

transient conditions.

The integrated design aids in reducing voltage

over-shoot associated with trace inductance. The

low clamping voltage of the SM712 minimizes the

stress on the protected transceiver. The SOT-23

package allows flexibility in the design of “crowed”

circuit boards.
