TVS (Transient Voltage Suppressors) diodes are intended to protect electronic circuits from transient voltage spikes or surges. The GSOT03-HE3-18 is a unidirectional diode array designed to provide transient suppression. It has a peak pulse power rating of 450W and a working voltage range from 24 - 72V.

Applications

The GSOT03-HE3-18 can be used as a protection device in applications such as automotive electronics, consumer electronics, power supplies, communications, networking and industrial equipment. It is ideal for ESD (Electrostatic Discharge) protection in circuits that may be subject to shock, interference or noise.

In automotive applications, the GSOT03-HE3-18 can be used as an ESD protection device for the following components: wire harness systems, airbag systems, control systems, engine management systems, and chassis control systems. The diode array effectively suppresses the EMI (Electromagnetic Interference) that may be caused by electrical disturbances. It can be used in consumer electronics such as DVD players, VCD players and gaming systems.

The GSOT03-HE3-18 is widely used in power supplies, communications, and networking applications. Its superior characteristics protect sensitive transistors from damaging voltage spikes. It is also often used in industrial applications for motor control systems, robotic systems, digital/analog signal processing systems, and lighting/laser systems.

Working Principle

The GSOT03-HE3-18 uses a varistor principle to suppress the voltage transients.A varistor is a two-terminal nonlinear electronic component. When a voltage is applied to the varistor, the resistance of the material varies with the voltage applied. This phenomenon is known as nonlinearity.

The resistance changes in an exponential manner, and therefore, the varistor acts like an energy absorbing material. When treated correctly, the varistor will limit the peak surge voltage to a safe level. The GSOT03-HE3-18 is designed to clamp the voltage surge to the working voltage range, so that the surge will not damage the electronic circuit.

The GSOT03-HE3-18 consists of two segments: the body, which is connected to a ground lead, and the center pin, which is connected to the positive voltage lead. When a surge occurs, the current flows to the center pin and is diverted around the body, and the energy is dissipated as heat. The body is designed to optimize the energy dissipation, so that the voltage spike is dampened and the circuit is protected.

The GSOT03-HE3-18 is designed with a variety of features that improve its performance. It has a high peak pulse power rating of 450W, and a very low working voltage range of 24 to 72V, which makes it suitable for a variety of applications. The device also offers surge protection across all terminals, provides EMI protection, and is RoHS compliant.

Conclusion

The GSOT03-HE3-18 is a unidirectional diode array designed to provide transient suppression. It is ideal for ESD protection in automotive, consumer electronics, power supplies, communications, networking, industrial, and other equipment. The device has a peak pulse power rating of 450W and a working voltage range from 24 - 72V. The GSOT03-HE3-18 utilizes a varistor principle to suppress the voltage transients and works by diverting the current around its body and dissipating the energy as heat.
