TVS diodes are special purpose, two-terminal components, which are used as protection circuits in equipment and circuits in order to avoid damages caused by surge voltages. The SA100AHR0G is an example of a versatile and commonly used TVS diode, which can be used in numerous applications to protect against overvoltage and transient voltage spikes.

The SA100AHR0G is a dual common anode array package, which is made up of two back-to-back zener diodes with a low-capacitance. The package is designed for maximum protection in consumer electronics, such as gaming consoles, laptops, and home theatre audio systems. It has a stand-off voltage of 11.5V and a maximum clamping voltage of 15.6V, making it ideal for any circuit with a 5.1V operating voltage. The device also has a low dynamic resistance, which allows it to respond quickly and effectively to voltage transients.

In applications where overvoltage protection is needed, the SA100AHR0G can be connected in a variety of ways. In series mode, the device is used with a voltage source connected between its common anode and the desired circuit node to be protected. When a transient voltage spike occurs, the device will instantly clamp the surge voltage to its maximum clamping voltage of 15.6V, providing reliable protection.

In parallel mode, the device is connected between the power supply and ground. In the event of an overvoltage surge, the device will then go into conduction, limiting the voltage between the power supply and the ground to its maximum clamping voltage. This mode is very useful in cases such as AC adapters, where the device can limit the surge voltage and protect against a variety of common power supply failures.

The SA100AHR0G is also useful in automotive applications, where power supplies are faced with more severe voltage transients. It has an operating temperature range of -55°C to +125°C, which makes it suitable for automotive applications, as well as commercial and industrial applications. The device has been tested in accordance with IEC 61000-4-2, which is the international standard for surge immunity.

In summary, the SA100AHR0G is a versatile TVS diode, which is capable of providing reliable protection against overvoltage and transient voltage spikes. It can be connected in either series or parallel mode, allowing it to be used in a variety of applications. The device is also designed to be robust and reliable, meeting industry standards and providing a long lifetime of protection.
