MPLAD15KP26CAE3 Circuit Protection

TVS - Diodes: MPLAD15KP26CAE3 application field and working principle

Transient Voltage Suppressor diodes, also known as TVS diodes, are a specialized type of semiconductor diode designed to protect circuits from voltage transients caused by ESD (Electro-Static Discharge), EFT (Electro-Magnetic Field Transients), circuits from over-voltage or over-power conditions, and similar electrical events. The most common type of TVS diode consists of an N-type and a P-type connected back-to-back, forming a structure called a uni-directional or bilateral diode, that prevents current flow in either direction, depending on the voltage encountered.

MPLAD15KP26CAE3 Application Field

MPLAD15KP26CAE3 is a way to identify one type of TVS Diode. Designed for the consumer or automotive electronics industries, this type of TVS is most often used for EMI/RFI protection. The particular diode\'s application is best suited for use in power circuits and consumer electronics. The diode can operate with a working voltage up to 15kV, making it ideal for the protection of sensitive circuits from transients in the range of 7-15 kV. It also has a fast clamping response time of only 6.2 to 8.1 nanoseconds, making it effective at preventing short term voltage surges from reaching the circuit.

MPLAD15KP26CAE3 Working Principle

The working principle of the MPLAD15KP26CAE3 is based on the properties of the PNP-NPN silicon junction formed by its construction. When the circuit is exposed to a short term voltage transient, the forward voltage drop across the diode increases quickly. This rapidly increasing voltage causes an avalanche breakdown, in which the diode is momentarily driven to a very high current level. This sudden current jump is absorbed by the relatively low resistance of the diode, thus protecting the circuit. When the transient voltage passes, the junction returns to its more conductive state and the circuit is protected.

The MPLAD15KP26CAE3 diode is designed with a wide operating temperature range, so it can handle temperature extremes and still work reliably. It is also useful in a wide range of power circuits, including battery operated equipment and computing devices. Furthermore, its small package saves space and makes it easy to place in many circuit designs. This makes it a popular choice for many applications.

Conclusion

In conclusion, MPLAD15KP26CAE3 is a special type of transient voltage suppression diode that excels in providing transient voltage protection. It is designed specifically for consumer and automotive electronics and it comes with a wide operating temperature range. The MPLAD15KP26CAE3 is also small in size, making it easy to integrate into many existing kinds of circuit designs.
