Transient voltage suppressor diode, or a TVS diode, is an electronic device that is designed to protect electronics circuits from electrical transients, often caused by lightning or electrostatic discharge. The MART100KP170A is a unidirectional Transient Voltage Suppressor (TVS) diode that is molded into a DO-201AD package. It is designed to protect sensitive electronic components from overvoltage transients produced by multiple electrical events, such as lightning, load switching, or electrostatic discharge. This device can also provide surge current ratings up to 200A.

MART100KP170A has a wide range of applications, such as in system power surge protection, automotive electronics, and industrial applications. It is designed for use in AC/DC voltage applications, where primary power switch devices will be used to protect components from voltage spikes on the circuit. Additionally, the device can also be used to protect sensitive electronics from voltage surges on the output of the power supply.

The design of the MART100KP170A ensures wide surge current ratings, and is protected against over-voltage and over-current conditions. The device is designed to provide low clamping voltage and fast response to transients. It is made up of an ESD protection diode that is constructed of a thin layers that are held in a metal oxide semiconductor field effect transistor (MOSFET). The internal structure of this diode includes an N-channel depletion diode, two N-channel devices and two parasitic diodes. This two-stage protection is the key to providing superior ESD and surge protection.

The working principle of this diode is relatively simple; when a voltage transient occurs, it is intercepted by the diode, which then shunts it away from the device in order to provide the surge protection. The U shaped MOSFET structure is responsible for providing the low clamping voltage, and the two N-channel devices maintains the flow of current with a very low voltage drop. The two parasitic diodes are responsible for providing protection against electrostatic discharge (ESD) conditions.

In summary, the MART100KP170A is a unidirectional TVS diode which is designed to protect a variety of sensitive electronic components from overvoltage transients caused by multiple electrical events, such as lightning or load switching. Its wide application range and superior surge protection make it a popular choice for many applications. It works by intercepting the voltage transient and shunting it away from the device, and its U-shaped MOSFET structure provides a low clamping voltage and fast response time.
