TVS - Diodes, such as MASMBJSAC22, are electronic components used to protect sensitive circuits from damage from overvoltage conditions. This type of diode is designed to detect and clamp off surges in voltage so that it does not exceed a predetermined voltage, also known as maximum breakdown voltage. This way, any sensitive electronics on the circuit are protected from damage caused by high voltages.

To accomplish this, MASMBJSAC22 devices use a special type of diode referred to as a “transient voltage suppressor” (TVS). TVS diodes use an array of zener diodes, which are specifically designed to clamp off specific voltages. The breakdown voltage is engineered according to the application, and can range from a few volts up to a few thousand volts.

When faced with a voltage surge, the diode’s UVLO (Under Voltage Lock Out) threshold is exceeded and current starts to flow. This flow of current creates a voltage drop across the diode’s own internal resistance, allowing the diode to clamp off the voltage at its rated breakdown voltage (TVS breakdown voltage). As a result, the voltage never exceed that level and electronics on the circuit are protected from voltage-related damage.

MASMBJSAC22 diodes are widely used in different application fields, including automotive, tool motors, home appliances, chargers and servers. Automotive applications are particularly important, as they are used to protect against voltage fluctuations, spikes, and surges on the road, which can be caused by sources such as lightening or faulty lines. In these cases, when correctly employed, a TVS diode can significantly reduce the possibility of damage to sensitive electronic components.

In addition, the protection provided by TVS diodes can also be applied to other high speed switching circuits. They are used to protect circuits from electrostatic discharge (ESD) events, which can occur when a circuit board is handled improperly. TVS diodes are also used in sensitive communication circuits to prevent damage from voltage spikes or transients.

In short, MASMBJSAC22 are a type of TVS diode used to protect sensitive circuits from overvoltage conditions. They use an array of zener diodes, which clamp off voltage surges and prevent damage to the electronics on the circuit. These devices are used in a variety of application fields, including automotive, home appliances, and communication circuits.
