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 replaces four discrete components by

integrating two 12V and two 7V TVS diodes in a single

package. 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 SOT23

package allows flexibility in the design of “crowded”

circuit boards.
