TVS – Diodes are widely used components in electrical circuits for preventing or reducing the damage caused due to overvoltage. The most popular TVS–diode is the MASMBJ100AE3, which is used in automotive, industrial and communication applications. This article provides an overview of the application field and working principle of the MASMBJ100AE3.

The MASMBJ100AE3 is designed to protect sensitive circuits from damage due to lightning, power surges, ESD (electrostatic discharge), or inductive loads like high-frequency switching. The diode has a low forward voltage drop within 1.2V, low reverse leakage current and fast reaction times, enabling it to protect even sensitive systems from electrical overstress.

The device features a very robust construction that provides superior mechanical resistance to vibration and mechanical shocks, making it ideal for applications such as automotive and industrial electronics. The MASMBJ100AE3 has been designed to operate at a wide range of temperatures, ranging from -55°C to +175°C, making it suitable for a variety of operating conditions.

The MASMBJ100AE3 is designed to work when the applied voltage exceeds a certain level. When this happens, the diode will switch from a low–resistant to a very high resistance state, quickly removing the excess current from the circuit. This prevents further damage and thus helps to extend the product’s life–span.

The MASMBJ100AE3 is also designed to self–repair in case of an overvoltage condition. It has a built–in self–repairing chip, which can detect and repair any additional damage that may have been caused. This guarantees the diode’s long–term protection. The diode can be used in parallel with other components, to further increase its protection capability.

The device is also equipped with a trigger current, which is the amount of current that has to flow through the diode before it can start actively protecting the connected components. This is very important, as it prevents the diode from being triggered too soon and potentially damaging the other components in the circuit.

The MASMBJ100AE3 is a simple, easy–to–use device that can provide excellent protection against overvoltage, lightning, and ESD. It has a wide operating temperature range, making it suitable for a variety of applications. Its self–repairing chip ensures that the device remains functional even after suffering from an overvoltage event. Finally, the device has a built–in trigger current, which makes it possible to control the device’s response time. All in all, the MASMBJ100AE3 is an excellent choice for ensuring the safety of a wide range of sensitive circuits.
