A Transient Voltage Suppressor (TVS) diode is a type of electrical protection device used in electronic circuits. It is a specialized form of zinc-oxide surge protection device used for short-term protection of electronic components and circuits from overvoltage events. The SMBJ100A M4G is one of the new technologies designed and used to protect from such high-frequency, high-voltage surges.

The SMBJ100A M4G is a two-electrode device with a minimum breakdown voltage of 100V. It utilizes Zener-like breakdown to suppress overvoltage events, by clamping the voltage at the defined breakdown voltage. The breakdown voltage of the device is adjustable, allowing users to select the desired breakdown voltage for their application.

The practical operating range of the SMBJ100A M4G is 660V, making it an ideal choice for applications such as Automotive, Mobile Devices, DC-DC Converters, Set-Top Boxes, Notebook Computers, Printers, and LCD Monitors. The device has a high surge capability, making it suitable for suppressing spikes on power and signal lines.

The construction of the device is unique, with a high-impedance design that allows for low turn-on and reverse leakage current. This provides users with better protection of their circuits and better performance for the application than other traditional TVS diodes. The device also offers a simple mounting style, with mounting pins located on top of the package.

In operation, the SMBJ100A works by clamping any transient voltages above the device’s breakdown voltage. It works as a nonlinear resistor, diverting excess energy away from sensitive components. The breakdown voltage can be adjusted to the desired voltage by adding or subtracting a resistor to the circuit.

The device also offers an on-state Joule heating resistance, allowing users to choose the desired power dissipation level to protect their components. The on-state resistance of the device is very low, leading to a low overall leakage current and low power dissipation.

The SMBJ100A M4G is a highly reliable and cost-effective way to protect electronic components and circuits from overvoltage events such as lightning, power surges, and transients. The device offers a high clamping ratio and adjustable breakdown voltage with low power dissipation. It is an excellent choice for applications that require protection from these high-voltage transient events.
