MXSMBJ100A Circuit Protection

TVS - Diodes

A TVS (Transient Voltage Suppressors) diode, also known as a suppressor diode, is a diode with special protective characteristics designed to protect sensitive electrical and electronic equipment from harmful voltage transients triggered by lightning, power mains and electrostatic discharge. Transient Voltage Suppressors (TVS) devices release a high amount of power over a short period of time to clamp the transient, and prevent them from damaging the protected electronic equipment. MXSMBJ100A is a type of TVS - diode with specific application field and working principle.

MXSMBJ100A Application Field

MXSMBJ100A (MMS MBJ100A) is designed for use in any electronic circuits which require transient voltage protection. It is particularly suitable for suppressing transients caused by power supply mains and electrostatic discharge in consumer and computer products. Its low Vf enables the device to be used in high voltage applications, while its fast response time and high surge capability make it ideal for protecting high speed digital circuits from voltage transients.

MXSMBJ100A Working Principle

MXSMBJ100A diode works on the principle of reverse biasing. It works by allowing current to flow in one direction only. The diode is connected between a power source and the electronic device to be protected. When a voltage higher than the breakdown voltage of the diode is applied, the diode turns on and allows current to flow in the reverse direction, thereby dissipating the transient energy. This then clamps the transient voltage to a safe level and prevents the electronic device from being damaged.

MXSMBJ100A Features and Advantages

The features of MXSMBJ100A can be summarized as:

• Low Vf: It has a low voltage requirement of 5V and is suitable for high voltage applications.
• Fast response time: It responds quickly, in 5ns, thereby providing improved protection for high speed digital circuits.
• High surge capability: It offers a high surge capability of 1kW.
• Compact size: It can be used in either surface mount or through hole packages and is available in a variety of sizes, from ultra-small SOT23 packages to larger packages.
• Cost-effective: It is a cost-effective solution for providing protection from voltage transients.

The MXSMBJ100A diode is the ideal solution for protecting sensitive electronic devices from damage caused by voltage transients. Its fast response time, high surge capability, and low voltage requirement make it suitable for high voltage applications and digital circuits, while its compact size and cost-effectiveness make it the perfect choice for any application requiring transient voltage protection.
