TVS (Transient Voltage Suppressor) diodes are widely used to provide protection against transient spikes in voltage. The SMBJ20CA-QH is a popular TVS diode, offering fast response time and a wide operating range of 6.5V to 200V. It is designed to protect against electromagnetic interference (EMI) and overvoltage conditions, and is used in a wide variety of applications including power supplies, automotive electronics, industrial equipment, audio and computer equipment, and consumer electronics.

The SMBJ20CA-QH is a unidirectional TVS diode, meaning it will only conduct current in one direction. This makes it suitable for applications where protection against negative voltage transients is needed. It has a current peak pulse power rating of 600W and is available in a surface mount package. The SMBJ20CA-QH also offers both ESD (electrostatic discharge) and EFT (electrical fast transient) protection.

The SMBJ20CA-QH has a working principle based on the avalanche breakdown of the diode junction. When the applied reverse voltage exceeds a certain breakdown voltage, a large amount of current flows between the terminals of the diode. This avalanche current reduces the excess voltage to a safe level, providing protection for the circuit and other components. The junction temperature of the diode should be taken into account when selecting a suitable TVS diode for the application.

The SMBJ20CA-QH is suitable for a wide range of applications including power supplies, automotive electronics, computers, and consumer electronics. It is used to protect circuits and components from overvoltage, EMI and ESD. It is also suitable for applications where EFT protection is required. In addition, the SMBJ20CA-QH can be used as a voltage clamp for the protection of sensitive circuits from voltage transient events.

The SMBJ20CA-QH is an ideal TVS diode for a variety of applications. It offers fast response time, a wide operating range and high-current peak pulse power rating. In addition, it provides both ESD and EFT protection, making it suitable for use in both industrial and consumer applications. The low junction temperature and surface mount package make it easy to use and integrate into a wide range of applications.
