SM712 TVS Diode Data Sheet
■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
■The SM712 may be used to protect devices from transient voltages resulting from electrostatic discharge(ESD),electrical fast transients(EFT),and lightning.
■The SM712 replaces four discrete components by integrating two 12V and two7 V TVS diodes in a single package.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 SOT23 package allows flexibility in the design of“crowded”circuit boards
●Features
■400 Watts peak pulse power(tp=8/20us)
■Transient protection for high speed data lines
◆IEC61000-4-2(ESD)±15KV(air),±8KV(contact)
