TVS Diodes

Transient Voltage Suppression (TVS) diodes, also known as reference voltage suppressors, are a type of semiconductor device used to protect a system from electrical overshoot and overvoltage. The MSMCJ15AE3/TR is a surface mount TVS diode used in applications where transient electrical overvoltage needs to be prevented.

Application Field

The MSMCJ15AE3/TR diode is designed to be used for electrostatic discharge (ESD) and lightning surge protectors. It is commonly used on printed circuit boards (PCBs) for protecting high-speed communication lines such as USB, DisplayPort, and Ethernet. It can also be used to protect logic circuits, power actuators, and AC/DC circuits with low-level logic gates.

The MSMCJ15AE3/TR has a maximum peak pulse current of 15A, a maximum reverse surge current of 25A, a maximum peak pulse power dissipation of 500W, and a maximum clamping voltage of 67V. It has an 8-lead SOT-363 surface mount package with a low-profile construction. The device is halogen free, RoHS compliant, and AEC-Q101 qualified.

Working Principle

As current begins to flow through the diode, the diode generates a voltage drop and dissipates some of the voltage, ultimately helping it clamp the voltage at a comfortable level. During an overvoltage event, the diode\'s resistance decreases allowing it to transfer more current to the ground, thus dissipating the excess voltage. The TVS diode also acts as a short circuit, effectively shunting the overvoltage to ground.

The MSMCJ15AE3/TR is an ultra-low capacitance diode that is capable of transferring high current in a very short amount of time with minimal voltage drop. It has an operational frequency up to 6GHz, allowing for high speed communication lines to be protected from electrical overvoltage without any loss in signal integrity.

The diode also helps protect components from ESD events by providing fast clamping response time and low clamp leakage current. It has an ESD protection level of up to 15kV (HBM) and 8kV (CDM), helping to provide electrical overvoltage protection when exposed to electrostatic discharge events.

The MSMCJ15AE3/TR is a versatile and reliable diode designed to protect sensitive circuits and components from electrical overvoltage. With its high surge capability and low capacitance, it is suitable for use in a variety of applications such as ESD protection and lightning surge suppression.
