TVS-Diodes: SMBJ45CA-M3/52 Application Field and Working Principle

Transient Voltage Suppressor Diodes (TVS-Diodes) are widely used to protect sensitive electronics against overvoltage transients or surges. Specifically designed to protect against surge voltages generated by lightning strikes, ESD, and other sources of overvoltage. The SMBJ45CA-M3/52, a unidirectional TVS diode, is part of the SMBJ series from ON Semiconductor, manufactured by Diodes Incorporated.

Overview

The SMBJ45CA-M3/52 is a unidirectional TVS diode designed specifically for protecting electronic devices from overvoltage transients. This diode has a low stand-off voltage (VWM) of 30V (12V to 52V) and a maximum peak pulse power of 1500 W (Ippm), 8/20 μs waveform. The SMBJ45CA-M3/52 can be used to protect against overvoltage transients generated by lightning strikes, ESD, and other sources. It is made in a SOD-323 small package and is ideal for automotive applications.

Structure

The SMBJ45CA-M3/52 consists of an epitaxial layer diode and a zener diode. The structure of the TVS diode includes two layers of semiconductor silicon NPN that has a gradual transition region (GRT) between them. The GRT reduces avalanche breakdown voltage and allows the device to absorb more energy than other products with similar characteristics. The device also has a low stand-off voltage of 12V-52V.

Applications

SMBJ45CA-M3/52 TVS diodes are widely used to protect sensitive electronic components from overvoltage transients and surges caused by lightning strikes and ESD, as well as other sources of electrical overstress (EOS). This type of TVS diode is ideal for automotive and HVAC applications such as airbag systems, engine control systems, steering systems, and air-conditioning. They are also used for protecting components in many consumer electronic devices such as cell phones, TVs, digital cameras, and MP3 players.

Working Principle

SMBJ45CA-M3/52 TVS diodes are triggered by the release of a large amount of energy from an unexpected source, such as lightning strikes, ESD, or other sources of overvoltage. The diode then works in reverse mode, allowing an electric current to flow in the opposite direction to normal. This current then rushes through the diode, dissipating the overvoltage in the process and protecting the sensitive electronics.

Conclusion

SMBJ45CA-M3/52 TVS diodes are widely used to protect electronic components from overvoltage transients and surges. These devices have a low stand-off voltage and are ideal for automotive applications and consumer electronics. The working principle of these devices is based of the release of a large amount of energy from an unexpected source, allowing a current to rush through the diode, dissipating the overvoltage in the process and protecting the sensitive electronics.
