TVS - DIODES

The S2315 is an ultra-high surge current protector diode which is a member of the TVS Diodes family. It is designed to protect electronic equipment from the damages of electro-static discharge (ESD), electrical over-stress (EOS) and other load hazards.

It uses a Zener diode in tandem with a lateral TRIPLE MAN transistor in order to limit surge current and voltage and offers an excellent robustness to various external factors. The S2315 has a low-power dissipation and significant capacitance with low threshold. It is also resistant to momentary over-voltage and is useful for a wide range of applications.

Application

The S2315 is suitable for use in applications such as video recorders, computers, telecommunication systems and other electronic devices.

In video recorders, the S2315 provides protection from electrical transients by absorbing the energy of high-frequency voltage spikes, power surges, lightning strikes, and other ESD events. It prevents further damage to the electronic components in the device.

In computers, the S2315 protects internal components from the risk of ESD and EOS. It also protects the system from the effects of sudden voltage changes in the power supply caused by power surges, lightning strikes, and other external sources.

In telecommunication systems, the S2315 is a valuable component in protecting expensive and sensitive equipment from the harmful effects of ESD and EOS. It also prevents equipment failure due to abrupt voltage changes.

Working principle

The S2315 employs a Zener diode in tandem with a lateral TRIPLE MAN transistor, which work to form a protection circuit. The Zener diode plays a critical role in limiting over-voltages, as it will turn on and clamp any voltage above a predetermined level. The Zener diode is reverse polarized with respect to the transistor so that it turns on first, providing a current path to the transistor.

Once the Zener diode has turned on, the current path then transfers to the base of the transistor, allowing it to conduct current until the circuit is switched off. This prevents the further buildup of the voltage and stops the protection circuit from becoming overloaded. The S2315 also has a built-in capacitance to absorb and dissipate any transient energy.

The S2315 has superior reliability and excellent line-to-line performance compared to traditional TVS Diodes. Its low clamp voltage, high surge capability, and fast response time make it an ideal choice for a wide range of applications.

The S2315 is an ultra-high surge current protector diode that is designed to protect electronic equipment from ESD, EOS, and other load hazards. Its Zener diode and lateral TRIPLE MAN transistor work together to provide protection against voltage transients. The S2315 is suitable for use in video recorders, computers, telecommunications systems, and other electronic devices.
