TVS (Transient Voltage Suppressor) thyristors, also called Transil, are one of the most important components in the field of semiconductor electronic industry. The features of the device allow it to protect against the damaging effects of transient over voltages, or voltages which either rise suddenly over and then fall back below the desirable level or fall below the threshold. The TB1500L-13-F is a popular type of TVS thyristor.

The TB1500L-13-F is a two-terminal, unipolar, non-repetitive avalanche voltage-clamping thyristor with excellent heat dissipating capability. It is designed to protect against the damaging effects of transient over voltages or voltage which exceeds its peak pulse power rating. The device dissipates both avalanche and induced voltage to ground with an internal series resistor. The voltage can be clamped by connecting an external resistor.

The application field of the TB1500L-13-F is mainly in high voltage circuits. It is commonly used in data buses, power lines, and various other electronic circuits, such as battery or ultra-high voltage-sensitive devices. Typical applications of this device include AC/DC switching, power line over-voltage protection, over-current protection, ESD protection, suppressor/clamping, and reverse energy protection.

In order to understand the working principle of the TB1500L-13-F, it is first important to understand the concept of avalanche breakdown voltage. Avalanche breakdown voltage is the maximum voltage an electronic device can handle before it causes an avalanche breakdown due to its high intrinsic voltage breakdown. When the avalanche voltage is exceeded, the device enters an unstable state and a surge of electrons are released, which causes a brief current pulse. This current pulse is known as a surge current.

The TB1500L-13-F limits the over voltage by clamping the avalanche voltage within a predetermined range. The device contains an internal series resistor which is closely coupled with threshold voltage and its proprietary thermally enhanced silicon material. When the surge current exceeds its peak pulse power rating, the internal series resistor dissipates the voltage to ground.

The TB1500L-13-F is a cost-effective device with high performance and high reliability, which makes it an excellent choice for a wide variety of applications. It provides effective protection against transient over voltages, and can be used to protect against ESD, over-voltage and reverse energy. Furthermore, it comes with an internal series resistor to effectively dissipate the surge current.
