TVS diodes are highly reliable protection components used in high-voltage, high-current, high-power applications for protection against transients. The SMCG5629E3/TR13 is a unidirectional, total-power, non-punch through (NPTO) diode that is designed for surface-mount technology and is intended for use in electronic equipments. It features reverse-polarity protection, ESD protection, isolation, and excellent clamping capabilities.

The SMCG5629E3/TR13 is typically used in surface mount telephone line interface circuits (SLICs) as well as in PGA, I/O, RTL, ASIC, and microprocessor based applications. It is suitable for applications such as SMR, ISDN, DFNET, LMDS, BAS, PBX, VoIP, DSL, and optical networks. The diode has excellent voltage clamping ability up to 150A in 8/20µs pulse, and a guaranteed hold of 35A in 8/20µs pulse.

The SMCG5629E3/TR13 has a simple working principle. It is a double-layer diode which is made up of two diodes connected in parallel with opposite polarity. When an electric current passes through it, it will conduct electricity in one direction while blocking electricity from flowing in the reverse direction. This is the basic lifecycle of a TVS diode. In order to ensure effective protection of the device, it is important that the voltage is limited to a specific threshold.

The SMCG5629E3/TR13 features a low capacitance which is capable of handling high frequency transients. The TVS diode is designed for applications requiring a wide range of power handling capacity and outstanding thermal management. It has a low leak rate and is capable of handling transient scenarios from -200V to +350V. The leakage current is typically less than 5µA, and the clamping voltage is between +45V and +73V.

The SMCG5629E3/TR13 provides built-in protection to protect sensitive electronic circuits from both ESD and EFT transients. It is designed with a thermally-enhanced package, which enables superior heat dissipation compared to other packages. The TVS diode is RoHS compliant and meets the static-free lighting rejection requirements of IEC 60950-1 and EN 60950-1.

The SMCG5629E3/TR13 can be used in applications where there is a need to protect a critical circuit from voltage transients. Its simplicity and protection capabilities make it a great choice for high-power applications in consumer electronics, automotive, industrial, telecommunications, and medical applications. With its excellent clamping capability and low capacitance, the SMCG5629E3/TR13 provides superior protection against transient events.
