SM712 Asymmerical TVS Diode for Extended Common-Mode RS-485 PROTECTION PRODUCTS Description The SM712 transient voltage suppressor (TVS) diode is designed for asymmetrical (12V to -7V) 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), eletrical fast transients (EFT), and lightning. The SM712 features more than 500 Watts (tp = 8/20 μs) of power handling capability to accommodate the higher transient voltage levels which may be expected in extended commom 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.
