MASMLJ120CA

The MASMLJ120CA is a part of a series of TVS - Diodes specifically designed for protecting sensitive electronic equipment from ESD and surge transients.

Application Field

The MASMLJ120CA has been designed to protect sensitive electronic equipment from ESD and surge transients such as those caused by inductive loads, atmospheric discharges, lightning and EFT. It can be used in power supplies, computer laborites, telecommunications, industrial control, automobile industry, printers, digital cameras, gaming machines, and many other applications.

Working Principle

A TVS diode is a specialised form of a Zener diode. In response to an input voltage, the MASMLJ120CA will act like a normal rectifier diode and will not conduct until the input voltage exceeds the breakdown voltage (Vbr), which is typically referred to as the "clamping voltage". When the input voltage reaches this level, the diode will become forward biased and will clamp the input voltage to a safe level, which is typically referred to as the Peak Pulse Power Dissipation (P P P D).

Once the input voltage is clamped, the diode will remain in this state until the input voltage drops below the breakdown voltage (Vbr). After this, the diode will return to its original state. The speed of the response of the device is essential, as it is important that the diode respond quickly enough to protect the equipment. The response time of the MASMLJ 120CA is typically less than 1ns.

The MASMLJ 120CA is designed to withstand high surge power levels (P P P D) up to 2500 Watts. Its low profile surface mount package is suitable for surface mount applications and its high reliability makes it an ideal component for protecting your electronic equipment.

Conclusion

The MASMLJ120CA is a very efficient, reliable and cost effective choice for providing surge protection to sensitive electronic equipment. Its low profile surface mount design enables easy integration and it has a wide range of applications from power supplies to industrial control. Because of its high surge protection capability and fast response time, the MASMLJ 120CA is an excellent choice for protecting your electronic equipment.
