TVS diodes, also known as Transient Voltage Suppressors, are electronic components that limits or absorbs transient voltage surges. The SA100AHA0G is a commonly used unidirectional TVS diode designed to protect two-line low/high speed data line applications. It is intended for use in telecommunications, computer and peripheral equipment, consumer electronics, industrial controls, medical devices, automotive, and aerospace avionics equipment.

The SA100AHA0G has a low capacitance of 0.15 pF for high speed data rate protection and

The SA100AHA0G is constructed with a dual-mode protection structure, comprising a low capacitance TVS component in series with an external clamping network. The device serves as an absorber, protecting the circuit against inductively and capacitively generated transients. The external clamping network provides additional absorbtion power and offers a low resistance path for induced transients.

The SA100AHA0G has a low profile, making it ideal for applications where space is at a premium. It is also available in leaded, lead-free, and surface- mount versions, allowing it to be used in a wide variety of applications. It is compliant with RoHS, JEDEC, and TUV standards, and is rated at a maximum operational temperature of 125°C.

The SA100AHA0G’s working principle is based on the use of an external clamping network, which works in conjunction with the device’s low capacitance TVS component to reduce transient voltage surges. When an incoming transient voltage spike is detected, the SA100AHA0G’s low capacitance TVS component absorbs a portion of the transient voltage. The external clamping network acts as an absorber, diverting excess energy away from the sensitive components in the circuit, thereby protecting it from any damage. The device is capable of absorbing transients with peak voltages up to 28V.

In summary, the SA100AHA0G is a popular unidirectional TVS diode that is used for protecting two-line low/high speed data line applications. It is constructed with a dual-mode protection structure, comprised of a low capacitance TVS component in series with an external clamping network. Its working principle is based on the use of an external clamping network, which works in conjunction with the device’s low capacitance TVS component to reduce transient voltage surges. By doing so, the SA100AHA0G is able to effectively and reliably protect a variety of sensitive electronic components from the damaging effects of induced transients.
