SM712.TCT Description

Short technical summary and product information.

The SM712.TCT is a bidirectional TVS diode array from Semtech, specifically designed for protecting RS-485 communication interfaces. It contains two bidirectional channels with reverse standoff voltages of 12V and 7V respectively, and clamping voltages of 26V and 12V. The device can handle a peak pulse current of 17A (8/20µs) and a peak pulse power of 400W, making it suitable for suppressing transient overvoltages in data lines.

 

Key electrical characteristics include a typical capacitance of 75pF at 1MHz, which is optimized for high-speed signal integrity. The operating temperature range is -55°C to 125°C. The part is mounted using surface-mount technology and is available in the SOT-23-3 package (also known as TO-236-3 or SC-59).

 

This device is intended for applications requiring bidirectional protection on two separate lines, such as RS-485 transceivers, CAN bus systems, or other differential data interfaces. The low capacitance helps maintain signal quality while providing robust transient suppression.
