DESCRIPTION

The RSM712 transient voltage suppressor (TVS)

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

protection in multi-point data transmission

standard RS-485 applications. The RSM712 may

be used to protect devices from transient

voltages resulting from electrostatic discharge

(ESD), electrical fast transients (EFT), and

lightning.

The RSM712 features 400 Watts (tp=8/20s) 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 RSM712 minimizes

the stress on the protected transceiver. The

SOT-23 package allows flexibility in the design of

“crowed” circuit boards.
