TVS - Diodes:

Transient Voltage Suppression (TVS) Diodes are widely used in applications requiring protection from transient voltage spikes. These diodes are typically found in electronic circuits and have the ability to protect sensitive components from voltage surges. In recent years, Technology has progressed to the point where the use of TVS diodes in electrical systems is now almost essential. In this article, we will look at an example of a TVS diode, namely GSOT03-HE3-08, and explore its application field and working principle in more detail.

The GSOT03-HE3-08 is a unidirectional doide which offers an impressive protection against surge voltage. It is designed especially for use in automotive onboard power systems, photovoltaic inverters, and servers with high-speed IO ports. With a maximum peak pulse power at 68W, it offers the highest level of protection when placed in high-voltage environments. Plus, it has fast response time of less than 100ns for a 10/1000 μs waveform, reducing the risk of component damage from voltage transients. The GSOT03- HE3-08 even offers protection up to 650V in standard mode.

In terms of its working principle, the GSOT03-HE3-08 functions by clamping the voltage that exceeds a breakdown voltage. As voltage begins to surge, the voltage across the diode begins to increase as well, which causes the diode to become ‘ activated’. At this point, the diode becomes a low-resistance path for the surge current, which ‘shunts’ the current away from the components and prevents further voltage rise.

Exactly how the GSOT03-HE3-08 goes about this will depend on the type of circuit it is connected to. For instance, in cases of parallel connection, the diode will shunt the transient current away from the components. In circuits with resistors, capacitors and inductors, the diode will act as a resistor, limiting the current flowing to the circuit.

In short, the GSOT03-HE3-08 is a very versatile and highly reliable diode for transient voltage suppression. Its wide applications, coupled with its impressive capacity for protection, makes it a great choice for use in a range of electrical systems. With a response time of less than 100ns, it ensures that any transient voltage that passes through it is clamped, preventing any further damage.
