Transient voltage suppressors (TVS) are designed to protect sensitive electronic components from damage due to transient voltages. They are typically placed between an input and output of an electronic application. TVS diodes are a type of TVS device primarily used to protect against overvoltage transients.

The SL15.TCT is an ultra-low capacitance, bidirectional (unidirectional) unidirectional transient voltage suppressor. It is an integrated circuit that combines two Zener diodes on one semiconductor device. It is designed to operate with an extremely low clamping voltage, with the aim to minimize the effect of transients on the data lines of high-speed digital systems.

The TVS circuit of the SL15.TCT consists of two 5V Zener diodes connected in parallel, with each one rated for 1.5W. This allows the TVS device to support up to 10V of transient voltage without damage or decline in performance. It also features high-floating voltage operation, allowing it to start clamping at a higher voltage than its rated voltage. This helps to reduce the effect of transients.

The SL15.TCT is most commonly used in applications that require protection from negative and positive transients caused by electrostatic discharge (ESD) and electrical overstress (EOS). It is also suitable for applications such as automotive and communications. The TVS device offers high surge capability, allowing it to easily absorb multiple transient pulses without damage or performance deterioration.

The working principle of the SL15.TCT is quite simple. When a transient voltage is applied across the two terminals of the TVS device, it acts as two Zener diodes connected in parallel. This results in a low-voltage clamping of the transient voltage. The two Zener diodes in the SL15.TCT are rated for 5V, allowing it to support up to 10V of transient voltage without damage or decline in performance.

The SL15.TCT also features a wide operating temperature range of -55°C to +150°C. This allows the device to operate reliably in a variety of environmental conditions. Additionally, the device is capable of handling high levels of transients up to a specified pulse width and pulse repetition rate.

In summary, the SL15.TCT is a low-capacitance, bidirectional TVS diode designed to protect sensitive circuits from transients caused by ESD and EOS. It is capable of handling up to 10V of transient voltage without damage or performance degradation. The device features a broad operating temperature range and can resist multiple pulses of transients within specified parameters.
