TVS - Diodes are among the most versatile and commonly used electronic devices in varied applications. They provide protection against electric transients such as overvoltage, overcurrent, and ESD. The SMBJ188D-M3/H device is one such product that is designed to provide an added layer of protection for all types of electrical equipment.

The SMBJ188D-M3/H has a low capacitance of 0.042 pF and an off-state of up to 1000V VBR (voltage breakdown rating). It has a fast response rate of <5 ns which makes it an ideal choice for high speed IC components. This device is housed in a small 2-pin SOD-123FL package.

The SMBJ188D-M3/H is suitable for use in consumer electronics, automotive, computational power supplies, educational equipment, and aerospace. It is primarily used to protect against electrostatic discharge (ESD) and overvoltage transients in automotive, communication, consumer and industrial applications.

The SMBJ188D-M3/H has a surge capability of 11A (8/20 μs) and is capable of blocking voltage transients up to 600V. It is designed to absorb electrostatic discharge without damage, thus protecting other components. It also has an ultra-low capacitance of 0.042 pF which prevents interference with high speed data signals.

The working principle of the SMBJ188D-M3/H is to be seeded with a positive voltage that is greater than its breakdown voltage and held steady. When the transient voltage is applied, it will turn the device on by increasing the current flow. This increases the voltage across the device until it reaches its peak breakdown voltage. At this point, the current is limited to its holding current which helps to protect the external components.

The SMBJ188D-M3/H is a low-power and durable device which is extremely useful for providing protection against electric transients. This component is well-suited for applications in a variety of fields, such as consumer electronics, automotive, computational power supplies, education equipment, and aerospace.
