Transient voltage suppressor (TVS) diodes are essential components that help protect sensitive electrical and electronic equipment against damage due to transient high voltage surges. The SM6T36AY TVS diode is a special type of bi-directional unidirectional diode that efficiently clamps a voltage surge and absorbs the transient energy. It provides superior protection against electrostatic discharge (ESD), electro-radiation, and power surges. The TVS diode also helps reduce power line noise, over-voltage, and surges, thereby improving system performance.

The SM6T36AY TVS diode is a low-capacitance, 600W, unidirectional diode. It has a passivation layer made of silicon oxide to protect components against mechanical damage and extended storage time without capacitance degradation. The SM6T36AY also has a low forward voltage drop of 1.5V and a reverse breakdown voltage of 36V. It also provides peak pulse power of 4A when in a ±20μs pulse.

The application field of the SM6T36AY are predominately in electrical and digital systems. The diode is mainly used to protect such components as I/O ports, communication ports, microprocessors, digital printers, and other sensitive components from overvoltage. It is also used in areas such as automotive applications, telecom applications, and defense applications.

The working principle of the SM6T36AY is simple. When a voltage surge occurs, the TVS diode diverts the surge away from the sensitive components by providing a clamped low voltage. The clamped voltage is equal to its peak breakdown voltage, which is 36V in this case. When the voltage exceeds the diode’s breakdown voltage, it starts conducting and diverts the voltage away from the sensitive components. This significantly reduces the risk of damage from transient overvoltages.

In addition to its low-capacitance and low forward voltage drop, the SM6T36AY has excellent electrical isolation. Its isolator layer helps prevent the flow of electrons from one component to another, thus providing excellent isolation between components. This significantly reduces the risk of electrical shorts in sensitive components.

In summary, the SM6T36AY is a low-capacitance, 600W, unidirectional, bi-directional TVS diode. It has a low forward voltage drop of 1.5V and a reverse breakdown voltage of 36V. It is mainly used to protect I/O ports, communication ports, microprocessors, and other sensitive components from overvoltage. The working principle is simple – the TVS diode diverts the voltage surge away from the sensitive components by providing a clamped low voltage. It also has excellent electrical isolation due to its passivation layer.
