MXLPLAD15KP26CA Application Field and Working Principle

Introduction

The MXLPLAD15KP26CA is a high power unidirectional Transient Voltage Suppression (TVS) diode belonging to the SMAJ family manufactured by SEMTECH. The SMAJ family is part of the larger subcategory TVS - Diodes found in the larger field of Electronic Components. This diode is used for protecting both, AC and DC voltage lines from various kinds of external Transient Voltage events.

Particulars

Among its particular features, the unit has a power rating of 15 Watts, an Operational Stand-off Voltage of 28 Volts, a Working Peak Pulse Power of 71.4 Watts at 10/1000 uS, a Breakdown Voltage (VBR) of 24 Volts, and Clamping Voltage (VC) of 40 Volt at a Operating Ambient Temperature range of -55 to 125 Celcius. The typical capacitance is 1.35 to 1.6 pF.

Application Field

The MXLPLAD15KP26CA is meant to be used for various applications whenever electrical or electronic equipment needs to be protected from over-voltages. This equipment may include both AC and DC powered supplies and devices. It is suitable for applications such as power supplies, modems, phones, IOT devices, sensors and other consumer electronics including automotive equipment.

Working Principle

The MXLPLAD15KP26CA is a type of semiconductor device used for Transient Voltage Suppression (TVS) materials which work based on a basic diode function: A PN junction. The diode works by restricting current from flowing in one direction, and allowing it to flow in the other. When a voltage pulse causes a sharp increase in current that exceeds the device\'s maximum rating, the TVS responds and "dissipates" the excessive current. In other words, it reduces, or "shunts" it back, thus preventing damage to the connected devices.

Conclusion

In conclusion, the MXLPLAD15KP26CA is a short term over-voltage protection diode belonging to the family of Transient Voltage Suppression (TVS) Diodes produced by SEMTECH. It is suitable for AC and DC powered applications that require high power protection from various voltage pulse events. The diode operates following the basic principles of a PN junction, which restricts and “dissipates” any current spike that exceeds its maximum rating, thus protecting the connected electronic equipment from damage.
