MPLAD15KP150CAE3 Circuit Protection

TVS-Diodes, or transient-voltage-suppression diodes, are devices used in electronic circuits to provide protection against electrostatic discharge (ESD) and other transient overvoltage conditions. The MPLAD15KP150CAE3 is a type of TVS-Diode, specifically designed for an automotive environment. It has a maximum peak pulse power dissipation of 1500 watts, a peak pulse current of 30 amperes, and a peak pulse breakdown voltage of 150 volts.

The purpose of the MPLAD15KP150CAE3 is to protect sensitive circuit components from the unwanted effects of fast rising, damaging voltages that exceed the resilience of the components. This type of diode can also be used for over voltage protection of sensitive switching circuits, and provides protection against transient voltages that are significantly greater than normal operating voltages. The ESD protection design stops transient voltage streaks by quickly clamping to a tolerated level, allowing the circuit to keep functioning for long terms.

The MPLAD15KP150CAE3 comes in a variety of package configurations. It is available in a low-power single-line SMD, a low-power dual-line SMD, and a high-power dual-line SMA. All of these packages offer advanced clamping performance, low capacitance, and low leakage current, making them suitable for use in high frequency and automotive applications.

The working principle of the MPLAD15KP150CAE3 is based on a Zener breakdown effect. This effect involves allowing a large current to flow through the diode, causing an abrupt increase in the voltage across the diode. The Zener voltage is the voltage level at which the device breaks down. When the voltage reaches this level, the current is diverted to a low-impedance path. This current flow limits the voltage, resulting in the diode having a predictable and repeatable clamping voltage.

The MPLAD15KP150CAE3 is designed to protect a wide range of automotive applications including engine control, powertrain control, sensor control, and ECUs. Its high pulse power capability makes it suitable for even high-voltage automotive applications, while its low on-state and clamping voltages ensure an excellent protection-to-cost ratio.
