PACDN006MR

TVS - Diodes

A TVS diode (Transient Voltage Suppressor Diode) is a type of semiconductor device often used to provide protection from high-energy transients found on various electronic lines and devices. TVS diodes are designed to protect against electrostatic discharge (ESD) and other types of electrostatic transients. They can also protect against very high voltage transients that could be generated by an electrical surge or spike, such as those caused by lightning strikes while blocking out the relatively low steady-state voltage with negligible leakage current and low surge response time.

PACDN006MR Application Field and Working Principle

The PACDN006MR, from Pacific Semiconductor, is a TVS diode designed for the protection of low-voltage electronics, such as logic circuits and on-board communication systems. It can absorb high energy transients up to 6V DC, providing protection for electronics from electrostatic discharge, surges and spikes in the power supply. The PACDN006MR is a unidirectional device, meaning it can only protect against signals travelling in one direction, and is optimized for applications where handling of high-energy transients is important. The PACDN006MR has a fast response time, typically less than 5 nanoseconds, and is capable of withstanding peak pulse power of up to 600 watts without failure.

The PACDN006MR utilizes avalanche breakdown technology, which works by allowing electrons to gain enough speed and energy to become “free” from their atoms, causing an electrical current. When the PACDN006MR is exposed to a high voltage surge, the avalanche breakdown phenomenon occurs, and a large number of electrons are released, allowing current to be conducted in an uncontrolled way. This effectively causes the surge to be “shorted out” before it can reach the low-voltage electronics. The PACDN006MR is also designed to “self-protect”, which means that it will degrade and not function properly once its power absorption or ESD protection limits are exceeded. This allows it to effectively protect the circuits it is protecting in cases of extreme voltage spikes or electrostatic discharge.

Overall, the PACDN006MR is an effective and reliable way to provide ESD and surge protection for low-voltage electronics. Its low capacitance rating and fast response time make it ideal for applications where high-energy transients must be handled quickly and effectively. The device’s ability to self-protect itself when its power absorption and ESD protection limits are surpassed also makes it an attractive protective device.

The PACDN006MR has a wide range of application fields, including automotive, aerospace, and telecommunications systems. In automotive applications, it can be used to protect on-board communications, ensuring that vital information is not lost or corrupted in the event of an electrostatic discharge. In aerospace applications, it can be used to protect on-board electronics from high-altitude radiation and extreme temperatures. And in the telecommunications industry, it can be used to protect telecom lines and equipment against electrical surges caused by lightning strikes.
