The SM712 is a Transient Voltage Suppressor (TVS) Diode, designed for asymmetrical 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 features 400 Watts (tp = 8/20μs) 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.
