The MPLAD15KP120A Transient Voltage Suppressor (TVS) is an advanced protection diode designed to protect sensitive electronic circuits from sudden transients due to electrostatic discharges (ESDs) or transient overvoltages. The device is capable of providing both unidirectional and bidirectional protection and is designed to withstand voltages higher than its rated voltage. It is widely used in automotive, industrial, and consumer applications to safeguard devices from transients or surges.

The MPLAD15KP120A is an axial-lead diode constructed with two lead configuration and two separate dies in one package. It features low dynamic resistance (RDS) and high peak-pulse power capability of up to 120 A. It is designed to be used in a variety of applications, including automotive electronic systems, power supplies and power circuits, industrial grade data systems, and consumer electronic products. It is also suitable for use in signals and data, video, graphics, and audio systems.

The MPLAD15KP120A diode protects electronic circuits by clamping a voltage above or below the specified working voltage range. The device consists of a two-sided metal oxide junction that is connected between the anode and cathode terminals. When the voltage at the anode terminal of the TVS exceeds the rated breakdown voltage (VBD) of the device, the junction becomes a low resistance (RDS) diode, allowing current to flow from the anode to the cathode terminals. At the same time, the voltage at the anode terminal of the TVS is limited to VBD to protect the protected circuit from overvoltages. The MPLAD15KP120A also features reverse-current and electro-static discharge (ESD) protection for protecting the device from accidental damage due to external overvoltage and static discharges.

The MPLAD15KP120A is also designed to provide excellent thermal management, allowing it to perform reliably in high-temperature environments. It features an internal shield that reduces secondary breakdown and improves power handling capability. Additionally, the device has a low thermal resistance junction-to-case (RTS) that allows for faster thermal dissipation for improved reliability.

The MPLAD15KP120A provides cost-effective and reliable transient protection solutions for a variety of applications. The device is available in two lead versions, SMA and DPAK packages, and features a low overall cost for high-volume volume production. Its low thermal resistance and high peak-pulse capability make it ideal for providing reliable protection in automotive, industrial, and consumer applications. Additionally, the device is RoHS compliant, making it a safe and environmentally friendly option.
