SMF6.0A-T13

TVS - Diodes

The TVS diode is a particular type of diode which has both a high surge withstand rating and high peak pulse current capability. It’s designed to protect electrical equipment from transient overvoltages caused by lightning, switching operations, or power faults. The SMF6.0A-T13 is a particular type of TVS diode which incorporates a unidirectional configurationin a small SMP package.

Application Field

The SMF6.0A-T13 is a high-speed transient-suppression diode that has a host of applications, most notably in telecommunications equipment, line protection, and surge suppression. It’s also used as an ESD protector and in frequency discriminator circuits. The SMF6.0A-T13 is a unidirectional (vs. bi-directional) device, meaning it only conducts current in one direction. This facilitates surge and over-voltage protection for equipment that is powered by AC mains.

Working Principle

The SMF6.0A-T13 employs voltage-dependent silicon oxide structures (VDSAS) and a dual anode structure. The dual anode structure provides stacked breakdown voltage in comparison with regular TVS diodes. These two components combine to create a uniquely versatile, reliable, and simple circuit configuration. When the voltage across the anode increases beyond a certain critical point (known as the breakdown voltage), a transient current flows through the VDSAS component and the dual anode structure. This conducts the surge away from the target equipment, dissipating the excess energy as heat.

When compared to regular TVS diodes, the SMF6.0A-T13 has higher surge current capability and higher peak pulse power dissipation. It also has an improved switching speed, which improves noise immunity. Furthermore, it boasts low capacitance and a low thermal resistance. These features ensure that the SMF6.0A-T13 is an effective, reliable, and durable solution for surge suppression.

Conclusion

The SMF6.0A-T13 is a high-speed, unidirectional TVS diode that offers superior protection from transient overvoltages caused by lightning, switching operations, or power faults. It has higher surge current capability and higher peak pulse power dissipation than existing TVS diodes, and it features improved switching speed and low capacitance, making it an ideal solution for surge suppression.
