Transient Voltage Suppressor (TVS) diodes, or “Zener” diodes, are semiconductor devices designed to protect circuits from voltage transients, or surges. The GSOT15C-G3-18 is a high-performance, low-capacitance, low-capacitance TVS diode that is suitable for both single- and multi-line applications in electronic equipment where overvoltage and ESD protection is essential. It is specifically designed to provide transient protection for both voltage and current transients.

The GSOT15C-G3-18 is a diode capable of operating up to 1500 Volts and capable of handling peak pulses of up to 1.5kW. It operates in the reverse breakdown region where the voltage exceeds the breakdown voltage or the avalanche voltage. Once the breakdown voltage is reached, the diode quickly conducts high current and limits the voltage to the breakdown voltage. This is why TVS diodes are commonly referred to as “crowbar” or “Zener” diodes.

The GSOT15C-G3-18 has a reverse leakage current of 6uA and a capacitance of approximately 18pf. It is constructed using an epoxy molding compound for environmental protection. The maximum peak power dissipated is 1.5KW and it is capable of dissipating power up to 80mW for 8 hours. The working temperature range for the GSOT15C-G3-18 is -40°C to +125°C.

The main application of the GSOT15C-G3-18 is in the protection of electronic equipment from transient voltage as well as electrostatic discharge (ESD). It is designed to suppress voltage transients in a broad range of applications including computers, communications systems, automotive, industrial systems, consumer electronics and other equipment that require reliable protection from damaging voltage pulses. For example, the GSOT15C-G3-18 can be used to protect communications lines, power systems, industrial systems, and consumer electronics facing an external surge. It can also be used in multi-line protection applications such as switch matrices, circuit breaker matrices and protection circuits.

The working principle of the GSOT15C-G3-18 is based on voltage and current surge protection. It is designed to protect against spikes in voltage and current that are too short for traditional circuit breakers to detect and respond to. When the voltage or current exceeds the breakdown voltage, the diode acts as a short circuit, reducing the voltage or current to a safe operating level and protecting the circuit from being damaged. The diode can also protect against the static energy that is produced by the transfer of electronic and electrostatic charge between two solid materials. The TVS diode acts as a low capacitance current path, dissipating the static energy without causing any damage to the application.

The GSOT15C-G3-18 is a reliable, low-cost, low-capacitance, high-performance TVS diode that can provide protection against transients and ESD in a variety of electronic applications. Its reverse leakage current, high voltage, high peak power, and low capacitance make it an ideal solution for overvoltage protection. Applications such as switch matrices, circuit breakers matrices, and communication lines can benefit from the reliable protection of the GSOT15C-G3-18.
