TVS (Transient Voltage Suppressor) diodes are an active form of surge protection device offering an effective protection against transients occurout in power lines. SA22AHA0G, as a TUX diode, is designed to protect the AC power lines from over voltage transients. There are two types of protection circuit configurations to fit different noise immunity and performance requirements: AC power line protection and DC power line protection.

As an AC power line protection configuration, the SA22AHA0G is used to protect AC lines from transients that occur from a voltage or current overload. The diode works by absorbing the transient energy and preventing it from passing through the power line and damaging other components connected to it. The diode can also protect against over-voltage or under-voltage conditions. In addition, the SA22AHA0G can also be used in DC power line protection circuit configurations.

The working principle of the SA22AHA0G is based on the principle that when a transient occurs, the diode acts as an open switch to allow current to pass through the power line. The diode then absorbs the transient energy and prevents further transients from passing through the power line. The diode can also be used to protect against overvoltage and undervoltage conditions.

The SA22AHA0G is typically used in applications such as power supplies, AC adoptor, MDD, telecom, and automatic control systems. It is also used in a wide range of consumer electronics such as computers, TV sets, digital cameras, and cell phones.

The SA22AHA0G has a reverse voltage of 25V and a maximum surge current of 3000A. It is a three-terminal device with anode, cathode, and control terminal. The anode is connected to the positive terminal of the power supply and the cathode is connected to the negative terminal. The control terminal is used to control the breakdown voltage.

The SA22AHA0G is an effective surge protection device that offers protection from transients occurring in power lines. It is suitable for many applications and can provide excellent protection against transient overvoltage and undervoltage conditions. It is a reliable, cost-effective and efficient device for protecting electronic devices.
