SMCG5662E3/TR13

The SMCG5662E3/TR13 is a transient voltage suppression (TVS) diode that is designed to protect sensitive electronic devices from electrical overstress. Its Transient Voltage Suppressor (TVS) diode is a two-terminal, voltage-dependent, unidirectional device consisting of a junction diode electrically connected in series with a metal-oxide varistor (MOV). The device absorbs power in the form of electrical transients, dissipating it as harmless heat, thus preventing the overvoltage to the load.

The SMCG5662E3/TR13 device is a unidirectional Transient Voltage Suppressor (TVS) diode used for protection of circuits against voltage and/or current transients. This device is extremely useful for applications that require protection from overvoltage transients in medium-voltage power circuits. This component is lead-free and RoHS compliant.

A key application for the SMCG5662E3/TR13 is the protection of critical components and circuits from overvoltage transients and surge currents generated in power systems. It is used in applications where a single transient can cause damage to sensitive electronics. These circuits can include but are not limited to telecommunication systems, automotive systems, and computer networks.

The working principle of the SMCG5662E3/TR13 is based on avalanche breakdown. When the voltage between its two terminals exceeds the specified voltage level, the device enters the avalanche region in which an avalanche current is triggered. This sharp rise in current is due to the multiplication of the carriers. Thus, the high surge current produced" snuffs out" the high voltage surge. The device then reverts to its “OFF” state, when the surge is over, and the forward voltage across its terminals returns to a safe value.

The SMCG5662E3/TR13 has various advantages such as low operating voltage (7.5 Vdc for reverse recovery), fast recovery time (less than 1.0 µs for off condition), low capacitance at high frequency (less than 1.0 pF for IEC 61000-4-<<2 ESD pulse), low clamping voltage, high surge current (6 A), and low current drain in device off condition (less than 500 nA).

In conclusion, the SMCG5662E3/TR13 is an extremely useful protective device in medium-voltage power systems. It is designed to protect sensitive electronics from electrical overstress by dissipating surge voltage energy as harmless heat. The device is lead-free and RoHS compliant. It offers many advantages such as low operating voltage, fast recovery time, low capacitance, low clamping voltage, and high surge current.
