MAPLAD15KP43AE3

TVS - Diodes

The MAPLAD15KP43AE3 is a Transient Voltage Suppressor (TVS) device. It is a diode that can be used to protect sensitive electronic components in a circuit from excessive voltages. The device works by attempting to limit or suppress any voltage that rises above the zener voltage of the device and diverting it to ground.

Application Field

The MAPLAD15KP43AE3 is most commonly used in diagrams to protect from electrostatic discharge (ESD) events, electrical surges, or overvoltage situations such as automotive and aviation applications. It can be used to protect signal lines, data lines, or power supplies. The device can also be used in applications that require protection from transient events with minimal consumption of power.

Working Principle

When an electrical surge rises above the zener voltage of the MAPLAD15KP43AE3, the device will divert the current to ground. This is done by the p+ and p- layer of semiconductor materials that are present on both sides of the device. When a reverse voltage is applied, the p- layers become conductive and quickly diverts the current to ground. This reduces the amount of time that the surge has to affect the other components in the circuit. Additionally, the device only conducts current during the transient event, and after the surge has passed, it returns to its non-conductive state.

The MAPLAD15KP43AE3 device is designed to withstand even higher voltage surges such as up to 15KV and is UL recognized with a wide range of operating temperatures from -40°C to +95°C. This makes it suitable for a variety of high-temperature and automotive applications.
