Asymmetrical TVS Diode for Extended Common

DESCRIPTION

The SM712 transient voltage suppressor (TVS)diode is designed for asymmetrical (12V to data transmission standard RS- 485 applications. The SM712 may resulting from electrostatic discharge(ESD), electrical fast transients (FET), and (tp=8/20μs) of power handling capability to accommodate the extended common mode applications. This provides higher equipment when using zener diodes that are not ra ted to handle such transient conditions.The integrated design aids in reducing voltage over- shoot associated with trace inductance.

  • Networks Asymmetrical TVS Diode for Extended Common -Mode RS-485 The SM712 transient voltage suppressor (TVS)diode is designed for asymmetrical (12V to 485 applications. The SM712 may be used to protect devices from transient resulting from electrostatic discharge(ESD), electrical fast transients (FET), and lightning. The SM712 features 400 Watts handling capability to accommodate the higher transient voltage levels which may be applications. This provides higher equipment reliability and eliminates the “ guess work” ted to handle such transient conditions.The integrated design aids in reducing voltage shoot associated with trace inductance.
