Transient Voltage Suppressors (TVS) are composed of Thyristor networks. They are most commonly employed in applications involving data security and communication. The 3KASMC33AHE3_A/H belongs to a category of TVS devices which provide unidirectional current protection against transient high frequency spikes typically from an EFT (electro- magnetic field interference) source. The 3KASMC33AHE3_A/H TVS device is designed as part of a multichip assembly for semiconductor protection and electro-static discharge (ESD).

The main application field for the 3KASMC33AHE3_A/H TVS device is for data security and ESD protection. It is used to protect sensitive data in multiple communication channels with any digital equipment, such as personal computers, servers, workstations, and other types of digital apparatus. As a result, ESD protection is essential for protecting digital information stored in digital storage devices, such as hard disks. The TVS device also offers low capacitance disturbance, making it suitable for use in high speed communication applications.

The working principle of the 3KASMC33AHE3_A/H is that, when a high frequency transient voltage surge is detected and exceeds the breakdown voltage of the TVS device (typically ≥15V), the internal circuitry switches the devices into a low impedance low capacitance state. This fast switching enables the device to limit the magnitude of current and voltage transients at the same time. The low capacitance state of the device offers a minimum capacitive loading on the high-speed communication channel, thus providing more reliable data transmission.

The 3KASMC33AHE3_A/H TVS device also features a thermally activated self-levelling function. This allows the device to automatically adjust its clamping voltage with temperature. This makes the device suitable for use in a wide range of environments and in the presence of higher temperatures.

In conclusion, the 3KASMC33AHE3_A/H is a self-levelling unidirectional TVS device designed for ESD protection and data security. Its fast switching, low capacitance disturbance and thermally activated self-levelling function makes it a suitable device for many digital applications and communication channels.
