TVS - Diodes

Transient Voltage Suppression (TVS) diodes are semiconductor devices that can be used to protect sensitive devices from electrical transients, also known as electrical surges. They are used in a variety of applications including automotive, consumer electronics, computers, telecommunications, solar power generation, and many other fields.

3KP15 Application Field and Working Principle

The 3KP15 from Littelfuse offers high performance, robust protection against electrical transients in an ultra-small package. This low-profile TVS diode is ideal for applications with limited installation space and offer increased flexibility and design freedom.

This TVS diode features two sets of anodes and cathodes that cross, making the 3KP15 a single bidirectional device. As an electrical transient occurs, the bidirectional device will conduct current in either direction, depending on which lead has the higher voltage. This allows the 3KP15 to be used in applications where surges or transients could occur in either the positive or negative direction. The 3KP15 also features a low on-state resistance and a high breakdown voltage of 1500 volts.

The 3KP15 also features an ultra-small SOT-666 surface mount package that allows the unit to fit into the most limited of spaces. This combined with its high performance makes the 3KP15 well-suited for applications such as hand-held devices, sensors, automotive circuit protection, computer memory cards, printers, or any other application where component height is limited.

Under normal operating conditions, the 3KP15 operates like a standard diode, however when an electrical pulse or surge is encountered, the 3KP15 will automatically divert the current to reduce the voltage in the protected electronics below the level that would cause it harm. This is done by the device diverting current to ground or to the power supply. The device then quickly restores itself after the surge, allowing it to be used again.

The 3KP15 from Littelfuse is a high-performing, robust protection device for a variety of applications. Its bidirectional functionality and ultra-compact design makes it an ideal choice for engineers needing a device that fits into limited spaces while still providing superior protection.
