TVS diodes (Transient Voltage Suppressor diodes) are specifically designed to protect sensitive electronics against surges induced by electrostatic discharge (ESD), electromagnetic interference (EMI), lightning, and other source. The GSOT15-HE3-18 is a TVS diode with a low stand-off voltage, specifically designed for ESD protection and applicable over an automotive temperature range from -40°C to +125°C. This TVS diode is optimized for high-speed switching and signal line protection.

The GSOT15-HE3-18 TVS diode is a silicon diode array in a three-pin SOT23 package. This device uses TRIO-TECH's patented three terminal design. It can be used in consumer, industrial, automotive and aerospace applications. This diode features low leakage currents (less than 0.05μA at rated working voltage) and low capacitance (100pF for BV=5V). This relatively small diode is capable of providing up to 18V clamping voltage.

The GSOT15-HE3-18 TVS diode is rated to 8A surge current. In order to ensure reliable operation and long-term product stability, it features a high power capability with i-PD technology as well as tightparameter distributions. Maximum power dissipation is 2.52W and internal impedance is less than 10mΩ. This low impedance helps to reduce the ground bounce by providing a lower loop inductance.

The working principle of GSOT15-HE3-18 TVS diode is based on the fact that it is a three terminal device made of two small diodes connected in inverse parallel. When a voltage surge is applied, the device clamps the surge voltage at a preset level. The device consists of a junction between two semiconductive materials. When a voltage exceeding a certain level is applied to the junction, the device conducts, allowing current to flow through it. It then quickly shuts off, limiting the voltage across the device. The two diodes clamp the surge voltage at different levels, depending on the peak surge current.

The GSOT15-HE3-18 TVS diode is suitable for ESD protection of data lines and low-level signal lines. It is also suitable for protection of low-voltage circuits from electrical transients such as lightning, electrostatic discharge, and electrical overstress. This diode can be used in a variety of applications, including consumer, industrial, automotive and aerospace applications. It is an ideal low clamping voltage TVS diode for ESD protection requirements.
