The PSM712 is an asymmetrical transient voltage suppressor

(TVS) array,

designed specifically for RS-485 applications. This device provides

protection

against ESD, tertiary lightning and switching transients.

The PSM712 has a peak pulse power of 600 Watts for an 8/20μs

waveshape and is available in SOT-23 package con-figuration.

This device meets the IEC 61000-4-2, 61000-4-4 and IEC 61000 -4-

5 requirements.
