SM712.TCT TVS Diode SOT-23

The SM712.TCT TVS Diode has its design for asymmetrical (12 V to -7 V) protection in multi-point data transmission standard RS-485 applications. It is useful in protecting devices from transient voltages resulting from electrostatic discharge (ESD), electrical fast transients (EFT), and lightning.

The SM712 features more than 500 Watts (tp = 8/20 µs) of power handling capability. So, it can accommodate the higher transient voltage levels which may be expected in extended common mode applications. This provides higher equipment reliability and eliminates the guessing work when using Zener diodes that do not have rating to handle such transient conditions.

The SM712.TCT TVS Diode replaces four discrete components by integrating two 12V and two 7V TVS diodes in a single package. The integrated design aids in reducing voltage over-shoot associated with trace inductance. The low clamping voltage of SM712 minimizes the stress on the protected transceiver.
