MAPLAD18KP13CAE3

Introduction to MAPLAD18KP13CAE3

MAPLAD18KP13CAE3 is a TVS (transient voltage suppressor) diode designed and manufactured by Diodes Incorporated, a leading semiconductor provider. It is a surface-mount package of a dual common anode ESD protection diode with a rated clamping voltage of 18V.

Application Field and Working Principle

MAPLAD18KP13CAE3 is typically used in portable consumer electronic devices to protect against electrical overstress (EOS) from digital and RF transients or accidental static discharges. It is designed to provide ESD protection up to 25kV contact for both typical IEC 61000-4-2 Air Discharge and IEC 61000-4-4 Contact Discharge. This dual common anode diode has low capacitance and ensures low reverse leakage current. The device has high peak pulse power dissipation and helps to eliminate the risk of latch-up.

The working principle of the MAPLAD18KP13CAE3 is similar to all other types of TVS diodes. The device consists of a pair of common anode diodes have different breakdown voltages. When a transient occurs, the diode with the lower breakdown voltage will begin to break down first, and the other diode with the higher breakdown voltage will remain conductive. This protective action causes the transient voltage to be clamped across the diodes, allowing the pass-through current to be regulated.

When an overvoltage transient does occur, the device is designed to absorb the current quickly and without thermal damage. This allows the device to provide fast response time of less than 1 µsec. Once the transient is over, the device is turned off and the current is no longer flowing.

The MAPLAD18KP13CAE3 device is suitable for multiple applications, including consumer electronics, automotive, and industrial applications. It is available in a variety of packages, including SOD-123, SOT-23, SOP-8, and more.
