TVS diodes have been used in industrial and technological systems for many years. The SMAJ200CA-H, in particular, is a surface-mount device designed to protect against electrostatic discharges which can be damaging to sensitive electronic circuits.

The SMAJ200CA-H is designed to be used in high voltage applications. It can operate at up to 200 Volts, and its breakdown voltage is specified to be between 125 and 175 Volts. This makes it suitable for applications such as automotive, telecom, industrial control systems, and other high voltage applications.

The SMAJ200CA-H is a uni-directional diode that functions like a valve, allowing current to flow in one direction, while blocking current from flowing in the other direction. This is achieved by its design – it features one common P-type side and two separate N-type sides.

Essentially, when exposed to voltage between the P-type and one of the N-type sides, electrons will flow and the diode will become forward-biased. This allows current to flow towards the other N-type side, thus blocking any current from flowing in the reverse direction.

However, in the event of an electrostatic discharge, the voltage can exceed the rated value, thus allowing current to flow in both directions. This damages the delicate components of a circuit, and can even cause a short-circuit.

The SMAJ200CA-H is designed to protect circuits from such dangerous curren surges. It has a low standing current, and its clamping voltage is specified at 15V above the breakdown voltage, ensuring that the current does not exceed the maximum sustained safe voltage. This helps to protect components from any surge effects.

The SMAJ200CA-H also features a low capacitance and low inductance, which, when connected in series with the circuit, helps to further protect components from voltage surges. This device also has a low insertion loss, making it suitable for high frequency applications.

In summary, the SMAJ200CA-H is a uni-directional TVS diode specifically designed for high voltage applications, such as automotive, telecom, and industrial control systems. Its breakdown voltage is specified to be between 125 and 175 Volts, and its clamping voltage is 15V above the breakdown voltage, ensuring that current does not exceed the maximum sustained safe voltage. Additionally, the SMAJ200CA-H has a low inductance and capacitance, as well as a low insertion loss, making it suitable for high frequency applications.
