TVS - Diodes

Transient voltage suppressors (TVS) are widely used in various electronics products, such as computers, phones, and other consumer gadgets. They are designed to protect individual integrated circuits (ICs) or even the whole circuit board from high-voltage transients that could cause them to fail or become damaged. The MXLSMBJ15CA is a special type of TVS diode, designed for transient suppression protection in automotive applications.

Application Field

The MXLSMBJ15CA is designed for automotive applications and can be used in various auto-grade products such as sensing and control units, power systems, and engine starters. It can also be used to protect high-voltage circuits such as transistors, thyristors, and microcontrollers, and is capable of withstanding both positive and negative transients and operating temperature range of -55°C to +150°C.

Working Principle

The MXLSMBJ15CA TVS diode is mainly designed for automotive applications and provides a reliable protection for all types of electronics circuits. The working principle of this TVS diode is based on the forward conduction of the device, which is triggered when the normal DC voltage applied across the device exceeds its forward-breaking voltage. At this point, the diode starts to conduct current, clamping the voltage over its breakdown voltage. The forward current causes the breakdown voltage of the device to rise, reducing the amount of current that can flow in the circuit. This prevents the voltage from reaching damaging levels.

In addition, the MXLSMBJ15CA TVS diode offers a fast response capability allowing it to respond to transients within 2ns. It also has high surge capability with a peak pulse current of up to 7800A. Moreover, it is able to dissipate up to 8 watts of power without any additional cooling limiting its power consumption, making it ideal for automotive applications which require reliable transient suppression.

Conclusion

The MXLSMBJ15CA TVS diode is designed for automotive applications and offers a reliable protection against transients and a fast response time. It has a wide operating temperature range and is able to dissipate up to 8 watts of power without any additional cooling. Moreover, it is designed to offer a high surge capability with a peak pulse current of up to 7800A. Overall, the MXLSMBJ15CA is an ideal solution for providing reliable and efficient transient suppression in automotive applications.
