Transient voltage suppressors (TVS) are also known as transient voltage surge suppressors or surge clampers. They are components used to protect circuits, microcontrollers, PCBs, etc from high voltage events caused by things such as electrostatic discharge (ESD) as well as from various other surges generated from switching circuits or electrical induction. The SM8S33ATHE3/I is a diode-based TVS component which provides a greater level of electrical protection from unwanted transient surges.

The SM8S33ATHE3/I TVS diode is found in various applications, especially ones where an external component is needed for additional protection. It has a reverse standing voltage of 8V, a unidirectional ESD protection level of 15 kilovolts (kV), a breakdown voltage of 5.5V to 8.8V, and a peak bidirectional ESD protection level of 8kV. It also has a clamping voltage of 35V, with a maximum capacitance of 5.2pF and a peak pulse power of 760W (10/1000μs waveform, 8/20μs). Other common applications for the SM8S33ATHE3/I diode include PCIe interfaces, USB ports, power supplies, and computer peripherals.

The working principle of the SM8S33ATHE3/I TVS diode is simple. When an external surge event occurs, such as an ESD or a switching noise from a device, the SM8S33ATHE3/I diode will start to conduct current. The current will be limited according to the clamping voltage and the surge energy will be diverted away from the protected device, limiting the damage during the event. This ensures that the devices will remain safe and operational even in the presence of high-voltage surges and ESD.

The SM8S33ATHE3/I diode is a reliable and robust TVS diode designed for protection against high voltage spikes and ESD. It is a low cost, small form factor component that is easy to install and provides reliable protection in various applications. It is commonly used in many consumer electronic applications such as USB ports, power supplies, and computer peripherals. With its superior protection capabilities and small form factor, the SM8S33ATHE3/I is an excellent choice for many applications.
