TVSs (Transient Voltage Suppressors) are widely used in electronic circuits for protection against transient voltage spikes. The SMBJ200CA-H is a popular diode which is used for this purpose. It is a fast-recovery, unidirectional, three-terminal device that can handle peak pulse power up to 200 watts.

The SMBJ200CA-H is comprised of a junction with two anode and cathode terminals, and a single gate terminal. The primary application field for this diode is general-purpose transient voltage surge protection. It is used in variety of applications including automotive, telecom, datacom, consumer electronics and industrial electronics.

The SMBJ200CA-H\'s primary function is to protect sensitive circuits in applications by clamping transient voltage spikes up to 200 watts. It is able to do this by providing a low on-state resistance. When the device is subjected to a transient voltage, the device turns on and clamps the voltage to a safe level. When the transient voltage passes, the device returns to its off-state with minimal reverse leakage current.

The working mechanism of the SMBJ200CA-H can be split into two separate steps. The first step is breakdown, and the second step is clamping. When a transient voltage spike is applied to the device, it undergoes a breakdown. This breaks down the depletion region and allows current to flow across the device. This turns the device on. In the second step, the device develops a voltage across it, which clamps the voltage to a safe level. This dissipates much of the energy in the transient voltage, protecting the system.

The SMBJ200CA-H is also designed for safety critical applications, due to its fast-recovery time. This is the time it takes for the device to return to its off state following a transient voltage spike. This is extremely important in preventing potentially damaging overvoltage conditions in sensitive circuits.

The SMBJ200CA-H is a popular device for transient voltage surge protection, as it provides fast-response time and high peak pulse power ratings of up to 200 watts. It is suitable for wide range of applications including automotive, telecom, datacom, consumer electronics and industrial electronics.
