MXLSMBJSAC45E3 Circuit Protection

TVS - Diodes - MXLSMBJSAC45E3 application field and working principle

Transient Voltage Suppressors (TVS) diodes are special components with the purpose to protect them against transient overvoltage. TVS´s come in a wide variety of packages, such as DO-41, SMD, and others. The MXLSMBJSAC45E3 is a very common TVS diode for use in many applications.

Applications

The MXLSMBJSAC45E3 is a uni-directional TVS diode mainly designed for automotive applications. Its wide range of operating temperature of -55°C to +125°C makes it ideal for use in harsh environment, such as automotive applications. Because it is unidirectional, it is ideal for protecting automotive components against faulty wiring, reverse current, and high energy spikes from induced signals.

The MXLSMBJSAC45E3 is also popular for use in other applications, such as:

• Data and communications
• Industrial and medical
• Home appliances
• Electronic circuits
• Analog and digital circuits
• High voltage and lightning circuits

Working principle

TVS diodes work by passing a nonlinear current through them. This current is amplified by the TVS diode and a voltage clamping is applied to the voltage. The current level is increased until it reaches a level where it becomes nonlinear. Once the current reaches this level, the voltage clamping is applied and the current is short-circuited, effectively suppressing and diverting the voltage spike.

The MXLSMBJSAC45E3 has a wide operating voltage range of 5.0V to 400V, which makes it suitable for a variety of applications. It also has a low reverse leakage current and a high peak pulse power of 1.25W. The peak clamping voltage is typically 41V, which is enough for protecting most components from high voltage spikes.

Conclusion

MXLSMBJSAC45E3 Transient Voltage Suppressor is a widely used TVS diode, especially designed for automotive applications due to its wide operating temperature range. It is also used in a variety of other areas, including data and communications, industrial and medical, home appliances, electronic circuits, analog and digital circuits, and high voltage and lightning circuits. Its working principle is based on passing a nonlinear current through the diode, which is then amplified and short-circuited in order to effectively suppress and divert voltage spike. The MXLSMBJSAC45E3 has a wide operating voltage range and a high peak pulse power, making it suitable for many applications.
