Tvs diodes are a type of semiconductor component that are designed to protect electrical circuits from excessive voltage or current. The MPLAD15KP11A model is one of the highest voltage fast-recovery Tvs diodes available in the market and it provides reliable protection of sensitive electronics from harmful over-voltages.

The MPLAD15KP11A model is a two-terminal, three-line (TPP) surface-mount diode and it can be used either as a single component or used in series with other Tvs devices to provide extended protection. The device has an extremely low leakage current (in the range of 1.0 to 2.0μA), virtually no reverse recovery time, and a fast response time of less than 3ns. This makes the MPLAD15KP11A ideal for use in automotive, medical, industrial and consumer electronics applications.

The device is capable of blocking transient voltages up to 15kV and conducting current up to 50A. The MPLAD15KP11A is available in a range of packages such as SOT-89, SOT-323, SOT-343, and SOT-553. It also includes an innovative “floating” gate protection diode, which ensures electrical isolation from the protection diode to the gate to minimize excess leakage current.

The working principle of the MPLAD15KP11A is based on avalanche effect. This process will generate carriers in a reverse biased diode, resulting in a current-voltage linear relation, and lower the potential of the p-region until the breakdown voltage is reached. Once the breakdown voltage is reached, the current will sharply increase, ensuring that the sensitive component won’t be damaged by the overvoltage.

Another advantage of the MPLAD15KP11A is that it can be used with voltage and current levels that are different from the breakdown voltage and the maximum delivery current. This makes the device well suited for applications where the high voltage level remains stable, but the current levels need to be frequently adjusted. This feature makes the MPLAD15KP11A a highly versatile component for many different applications.

Overall, the MPLAD15KP11A is an ideal bus-bar protection device, capable of protecting sensitive electronics from damaging over-voltage surges. It also offers an efficient and cost-effective way to protect a wide range of applications, from automotive to medical, industrial and consumer electronics. With its low leakage current, rapid response time, and avalanche protection, the MPLAD15KP11A is a highly reliable and durable Tvs diode that can provide long-lasting protection for a wide range of electronic circuits.
