B72220P3551K101

A TVS (Transient Voltage Suppressor) is a type of electronic component, such as a Varistor, MOV (Metal Oxide Varistor), or Diode, which protects sensitive electronic components from destructive surges of up to 300 volts. It is typically used to protect sensitive electronic components from power surges, lightning, and other high voltage transient events. The B72220P3551K101 is one such TVS and it is designed for use in ICT (in-circuit testing) applications where transient voltage suppression is needed in order to protect sensitive equipment from harmful overvoltages.

The B72220P3551K101 is a surface mount discrete TVS diode that provides overvoltage protection in single or dual line configurations. It is constructed with multiple PN junction diodes in a single package and provides high speed clamping for overvoltage transient protection. It features low dynamic resistance, high temperature cycling, low leakage current, low capacitance, and high surge capability.

The B72220P3551K101 TVS has a working voltage range of -30V to +175V and can be configured to clamp voltages up to +28V. The device has a response time of less than 5 nanoseconds, making it suitable for high speed circuitry protection. Its surge carrying capability is 1,555 Amperes as per the IEC 61000-4-5 standard, while its reverse leakage current is ≤ 200µA at 125°C. It also features Zener-like behavior at elevated temperatures, limiting the voltage across it to a specified value when the voltage exceeds the breakdown voltage of the diode.

The working principle of the B72220P3551K101 is simple. When the voltage of the incoming power supply exceeds the breakdown voltage of the device, the two PN junction diodes in the package turn on, clamping the voltage to a level that is safe for the connected electronic equipment. This process happens quickly, allowing the device to provide fast and effective transient voltage protection. The device is also capable of handling multiple transient voltage events, making it suitable for a wide range of surge protection applications.

The B72220P3551K101 TVS is versatile and can be applied in a variety of situations. It is particularly suited to industrial and automotive applications due to its fast response time, low leakage current, and high surge carrying capability. It is also suitable for telecommunications and general electronics, as well as other applications that require fast and reliable transient voltage surge protection.

In summary, The B72220P3551K101 is a surface mount discrete TVS diode that provides overvoltage protection in single or dual line configurations. It features low dynamic resistance, high temperature cycling, low leakage current, low capacitance, and high surge capability, making it suitable for a wide range of transient voltage protection applications.
