SR70-02CTG device is a type of transient voltage suppressor diode (TVS). This diode acts as a voltage regulator in order to protect sensitive components from activity of excessive surge voltages. It shields electronic circuits against power transients, while allowing normal voltages to pass unaffected. These TVS diodes can offer superior piezoelectric effect protection against fast transient overvoltages. SR70-02CTG devices have a wide range of uses in consumer electronics, automotive electronics, medical equipment, telecommunications and industrial and automation control.

The working principle of SR70-02CTG diode is based on a pn-junction. When voltage is applied to the diode, a barrier potential is created. The barrier potential causes a depletion zone that has an electrical field opposite to the applied voltage, preserving the stability of the device and thus limiting the amount of current flow. If the applied voltage exceeds the reverse breakdown voltage of the diode, normally a sudden breakdown occurs in which electrons and/or holes are swept across the junction, leading to a large current flow. The TVS diode can protect against large static voltages and those momentarily exceeded.

The SR70-02CTG diode is made with a bi-directional construction with a rapid turn-on time and low capacitive elements, offering superior protection from overvoltages. It is capable of suppressing multiple pulses, and features fast response times as well as low capacitance. The total power dissipation capability of this diode is an impressive 120W peak pulse power (1.2/50 μs) and 25A peak pulse current (10/1000 μs). The maximal continuous working voltage is 70V, while its breakdown voltage (VBR) is 75V. It also has low clamp voltage ratings, low leakage current once the VBR is reached, and superior clamping protection. These properties make the device suitable for use in a variety of applications, including consumer electronics, communication equipment, automotive electronics, and high-end computer systems.

The SR70-02CTG diode is housed in a small and space-efficient SOD-323F package, allowing for a compact and cost-effective design. The package is compliant with RoHS and environment-friendly requirements, making it a great choice for manufacturers and designers who are looking to keep their environmental footprint as low as possible. Additionally, the SR70-02CTG device is RoHS-compliant and features excellent tantulum barrier diffusion.

In conclusion, SR70-02CTG is a type of TVS diode suitable to be used in multiple applications. It features high-quality construction with a rapid turn-on time, low capacitance and excellent environmental-friendly properties. Additionally, it has impressive peak pulse power and current ratings and offers superior protection from transient overvoltages. It is thus a great choice for those looking for reliable overvoltage protection.
