05094 PSM712

600 WATT TVS ARRAY - ASYMMETRICAL DATA LINE PROTECTOR

DESCRIPTION

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.
