MAPLAD30KP64A is a type of transient voltage suppressor (TVS) diode characterized by a peak pulse voltage of 30 kilovolts and having a low incremental surge resistance with an 8-22pF dynamic conductor capacity of 1000A.

This series of TVS Diodes is designed for the protection of circuitry and ports integrating high-speed data lines from electrostatic discharges (ESD) and other over-voltage transients (OVP). It is an ultra small SMD package and very cost-effective.

At the time of this writing, MAPLAD30KP64A is mostly used in automotive, consumer, industrial, and other applications where transient voltage must be suppressed. Its working principle is simple: the diode is configured to shunt the ESD and other over-voltage transients to ground, or to dissipate the transient current in a protector element (MOV).

In an ESD event, the diode will become forward biased, and the current will flow from the ESD-caused transient voltage source to the diode’s cathode (ground). The diode will then divert the current of the transient event to the anode, which is connected to a ground plane or is a low impedance path. During this time, the diode will act as a short circuit between the ESD-caused transient voltage source and the anode. This will reduce the voltage on the anode and limit the voltage applied to the protected device, thereby protecting the device against an ESD transient event.

In an OVP event, the diode will be reverse biased and act as an open circuit when the voltage reaches its breakdown voltage. The diode will then become forward biased and the current will be diverted, similar to the ESD operation. The current will then be dissipated in a protect element, such as an MOV. In this type of situation, the diode will act as a safety device, limiting the voltage applied to the protected device and preventing any device damage.

In summary, MAPLAD30KP64A is a type of transient voltage suppressor (TVS) diode that is designed for the protection of circuitry and ports integrating high-speed data lines from electrostatic discharges (ESD) and over-voltage transients (OVP). It is characterized by a peak pulse voltage of 30 kilovolts and having a low incremental surge resistance with an 8-22pF dynamic conductor capacity of 1000A. It is mostly used in automotive, consumer, industrial, and other applications where transient voltage must be suppressed. Its working principle is that it will become forward biased when an ESD event occurs and reverse biased when an OVP occurs, thus limiting the voltage applied to the protected device and preventing its damage.
