SM712 TVS 400W ASYMMETRICAL TVS DIODE ARRAY
■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), electrical fast transients (FET), 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. The integrated design aids in reducing voltage over-shoot associated with trace inductance. The low clamping voltage of the SM712 minimizes the stress on the protected transceiver.
■The SM712 is available in SOT-23 package
