概览

The SVSM712S transient voltage suppressor (TVS) diode is designed for asymmetrical (12V to -7V) protection in multipoint data transmission standard RS-485 applications. The SVSM712S may be used to protect devices from transient voltages resulting from electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. The SVSM712S 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 common mode applications. The SVSM712S replaces four discrete components by integrating two 12V and two 7V TVS diodes in a single package. This provides higher equipment reliability and eliminates the "guess work" required when using Zener diodes that are not rated to handle such transient conditions.
