The SA110CAHR0G is a bidirectional transient voltage suppressor diode (TVS). The TVS can take the form of a unidirectional or bidirectional component, depending on the structure of the device. The SA110CAHR0G is a bidirectional type, meaning that it provides protection in both the forward and reverse directions.

A TVS diode typically consists of a zener diode and a parasitic thyristor junction. As current passes through the device, the zener and parasitic thyristor junctions work together to form a protection circuit. The TVS diode features a high surge current protection, low clamping voltage, and is also able to provide ESD protection. Depending on its design, a TVS diode can also provide protection in reverse polarity.

The SA110CAHR0G is a bidirectional TVS diode with a working voltage of 5.1V. It is ideal for a range of electronic device protection applications, such as automotive, communication, consumer, LED, and IoT. It features a maximum Ipp (Peak Pulse Current) rating of 110 A (8/20 µs). The device is also RoHS Compliant, and is available in a SOT-23 package.

TheSA110CAHR0G is suitable for a wide range of applications, including over voltage protection, transient protection, and ESD protection. The diode’s bidirectional design protects circuits from both positive and negative transients, and its low reverse leakage current allows for a low expansion of parasitic elements. The low clamping voltage ratings of the device ensure that the diode will not cause excessive voltage drop in the circuit.

The working principle of the SA110CAHR0G is simple. When the voltage across the diode exceeds the device’s nominal working voltage (Vw), the diode begins to conduct current. The clamping voltage of the diode is defined by the voltage at which the device stops conducting current. The diode then clamps the voltage across it to the clamped voltage, limiting the voltage rise and preventing damage to the circuit.

In summary, the SA110CAHR0G is an ideal choice for overvoltage protection in many different applications. It features a high surge current protection, low clamping voltage, and is able to provide ESD protection. The low reverse leakage current of the device allows for a low expansion of parasitic elements, and it is available in a SOT-23 package. The diode’s bidirectional design protects circuits from both positive and negative transients, and it features a maximum Ipp (Peak Pulse Current) rating of 110 A (8/20 µs).
