The SMCJ170A-13 Transient Voltage Suppressor (TVS) is a widely used component designed to protect sensitive electrical components and systems from high-voltage or surge-induced damaging current. This device is a bidirectional unidirectional TVS diode, meaning it will respond to both positive and negative power surges. It is widely used for over-voltage and ESD protection in consumer and industrial electronic devices.

The SMCJ170A-13 is a Zener diode based TVS diode. The Zener diode offers protection by converting higher voltage surges into lower voltage currents. The diode does this by changing its resistance when it is exposed to voltages higher than its reverse breakdown voltage. When the reverse breakdown voltage is exceeded, the diode starts to conduct, allowing a current to flow through it and limiting the voltage across the TVS device. This device also features lower clamping voltages, making it suitable for a wide variety of applications.

SMCJ170A-13 is designed to provide reliable and robust ESD, surge protection, and over-voltage protection for systems and sensitive electrical components. It offers an ultra low clamping voltage of 13V and its clamping range is from 13V to 16V. It also has a low capacitance between pins, which makes it ideal for high-speed applications such as USB and Ethernet. The TVS diode is a cost-effective, reliable, low-power solution, providing protection for systems and sensitive components.

The working principle of SMCJ170A-13 is based on the Zener diode, which provides protection when exposed to voltages higher than its reverse breakdown voltage (VB). When the voltage exceeds the breakdown voltage, the device will start to conduct and slowly reduce the current to an acceptable level. This will protect the system from further damage. The device also features an over-voltage protection circuit, which helps protect against errant voltage spikes.

In conclusion, SMCJ170A-13 is a reliable TVS diode used for ESD, surge, and over-voltage protection of sensitive electrical components and systems. It features a low clamping voltage of 13V and its clamping range is from 13V to 16V. The device also offers a low capacitance between pins, which makes it ideal for high-speed applications such as USB and Ethernet. Additionally, the device has an over-voltage protection circuit to help prevent further system damage.
