TVS is an acronym for Transient Voltage Suppressor and is a type of diode designed to protect sensitive electronic equipment and circuits from transients and electromagnetic interference (EMI). TVS diodes can also be referred to as spike suppressors, overvoltage protection diodes, and transient clamping diodes. They are designed to absorb extra high voltage, and clamp a voltage at a safe level to protect vulnerable components.

SM8S22HE3/2D is a silicon unidirectional TVS diode for ESD and surge protection, designed to offer excellent protection from transient voltage or pulse spikes. It has a wide range of working voltages and offers superior performance in data line applications. The SM8S22HE3/2D is an ideal solution for protecting against transients in consumer, industrial, automotive, communication, and computer applications.

In terms of its application field, the SM8S22HE3/2D can be used for various purposes, such as protecting power supplies from over-voltage transients, protecting RS-232 and RJ-45 Ethernet jacks, and protecting automotive CAN bus lines. It is also suitable for Analog and digital audio lines, High speed data lines, PCMCIA/PC card protection, pulse power and telecommunication equipment.

As with any diode, the SM8S22HE3/2D works on the principle of forward biasing and reverse biasing. During forward biasing, the anode receives a positive voltage and the cathode receives a negative voltage. This causes current to flow through the diode, allowing it to conduct. During reverse biasing, the anode receives a negative voltage and the cathode receives a positive voltage. This causes no current to flow through the diode, thus blocking any current from passing through it.

The unique feature of the SM8S22HE3/2D is that it is a Transient Voltage Suppressor (TVS) diode. This means that when the voltage across the diode exceeds the reverse breakdown voltage, the diode “clamps” the voltage at a safe level. This effectively absorbs the transient voltage, protecting vulnerable components from voltage spikes.

In summary, the SM8S22HE3/2D is a unidirectional TVS diode for ESD and surge protection offering excellent performance in data line applications. It is designed to protect sensitive electronic equipment and circuits from transients and EMI, and is suitable for a wide range of applications, such as automotive CAN bus lines, RS-232 and RJ-45 Ethernet jacks, and PCMCIA/PC card protection. The SM8S22HE3/2D works on the principle of forward and reverse biasing, and it is the unique TVS feature that make the diode particularly effective as a spike suppressor and for overvoltage protection.
