SA90A A0G is a general-purpose Transient Voltage Suppressor (TVS) diode designed to protect low voltage system. It is ideal for ESD and transient voltage protection applications.

The SA90A A0G is designed for protection devices in twenty-four pin (20- through 24-pin) packages with small-cell array layout. It is specifically geared to reduce devices’ susceptibility to premature breakdown caused by sudden spikes in voltage. The small size of the device and the low total capacitance both enable it to be used in very low voltage protection applications.

TVS diode is used to clamp down the voltages that are either too low or too high, and its operation is based on a reverse-biased Zener diode which limits the surge current when presented with excessive voltages. Once the voltage exceeds the breakdown voltage, the charging current flows through the reverse-biased diode. The breakdown voltage is determined by the junction’s gate, and it clamps the voltage to remain below the breakdown voltage.

The SA90A A0G offers high surge capability up to 1KV and is compatible with most single pin packages. It offers high quality ESD protection and exceeds the requirements of the IEC61000-4-2 standard. The device provides excellent ESD pulse waveforms, and is capable of handling fast transients, up to 10KV 8/20uS. It is constructed with low capacitance elements, and its low insertion loss reduces reflection and dampens transients widely across frequencies. Plus, it offers a ESD protection threshold of around +/-1KV.

The SA90A A0G is built with a low total capacitance of 2.2 pF to minimize delay times. Its fast response time helps keep system performance high, and its low capacitance values enable the device to be used in very low voltage system. This makes it especially useful for portable and embedded applications.

In addition, the SA90A A0G features a high surge current of up to 1KV. This supports high surge current pulses and helps protect low voltage systems from excessive voltages. The device also offers low clamping voltage and excellent clamping performance, allowing it to better absorb ESD pulses.

Overall, the SA90A A0G is a strong choice for ESD and transient voltage protection applications. It offers a wide range of features that enable it to be used in very low voltage protection applications. Its fast response time and high surge capability help keep system performance high while protecting low voltage systems from excessive voltages.
