SMCJ45A V7G

Transient Voltage Suppression (TVS) diodes, or surge protection diodes, are a type of semiconductor protected device used in electronic and computer systems to protect them from damage caused by high voltage spikes or transients that may occur in a circuit. The SMCJ45A V7G is a TVS diode specifically designed for transient voltage surge protection.

Features

The SMCJ45A V7G TVS body diode features a unique, wide-body package which allows up to a 6.2amp pulse capability, making it well suited for high speed switching circuit protection that is typically used in consumer and computer electronics. The SMCJ45A V7G also features low leakage current which is important for protecting sensitive electronics from the effects of voltage transients. The diode is also RoHS compliant and has a 5000W clamping voltage.

Application Field

The SMCJ45A V7G TVS diode is most commonly used in consumer electronics and computers to provide protection against voltage surges. The diode is also suitable for a wide variety of other applications such as automotive, wireless communications, power management and industrial control systems. This diode is also suitable for applications where space saving is a priority.

Working Principle

The SMCJ45A V7G TVS diode works by clamping the voltage when it exceeds a certain threshold. The diode has a breakdown voltage, and once this voltage is exceeded the diode will start to conduct and limit the voltage through the diode. This process will limit the amount of current that will be allowed to flow through the diode, thus providing protection against voltage surges and transients.

Conclusion

The SMCJ45A V7G TVS diode is a well-suited device for transient voltage surge protection in a wide variety of applications such as consumer electronics, computers, wireless communication, and automotive electronics. The wide-body package allows for a high current pulse rating along with low leakage current which helps protect sensitive electronics from voltage transients. The diode works by clamping the voltage when it exceeds a certain threshold.
