SMS15.TCT Circuit Protection

TVS (transient voltage suppressors) diodes are electrical components used in circuits to suppress voltage transients, which are short-duration electrical surges. In the event of a voltage spike, the TVS diode absorbs the excessive energy released to keep the circuit within a safe operating range. TVS diodes, also known as spike suppressors, are available in a variety of different technologies including unidirectional or bidirectional, and include the current SMD15.TCT.

The SMD15.TCT is a unidirectional device designed to protect against voltage transients that can overburden the equipment. It is designed to exceed the voltage surge performance, high capacitance, and high speed operation of its predecessor the SMD10.TCT. This Schottky diode is housed in a low profile Surface Mount Device (SMD) package and is equipped with fast response times. It can perform in a wide variety of temperatures from -60°C to +175°C.

The working principle of the SMD15.TCT is as follows. In normal operation, the diode passes current and only passes a small voltage drop across it. When the voltage spike crosses the VBR (voltage breakdown rating) of the diode, it starts to conduct current, and the spike is diverted from the equipment to the diode. The diode absorbs the spike energy in order to protect the equipment, after which it polarizes back to normal, allowing the current to pass through again.

The SMD15.TCT is suitable for a variety of applications, ranging from automotive to industrial and consumer electronics. It can be used in applications requiring high ESD protection of up to 18kV, such as for laptop and cell phone I/O ports, USB and HDMI ports, and touchscreens. It can also be used in automotive electronic applications such as fuel injectors or airbag inflators; and in industrial applications such as DC-DC converters, solar inverters, PLCs, or power management ICs.

In conclusion, TVS diodes like the SMD15.TCT are specialized components designed to protect other components in electronic circuits from voltage surges. The SMD15.TCT in particular is a unidirectional device designed to protect against voltage transients, while providing high capacitance and fast response times. It can be used in a wide variety of applications, from automotive and industrial, to consumer electronics, and provides effective protection against voltage transients.
