TVS (transient voltage suppressor) diodes are a type of electro-optical device used to protect circuits from voltage spikes. The D1213A-04MR-13 is a specific type of TVS diode used to protect circuits from damage due to over-voltage and transients. This article will discuss the application field of the D1213A-04MR-13, as well as its working principle.

Application Field

The D1213A-04MR-13 is designed for the protection of high-speed equipment, including computers and similar apparatuses. Its small size makes it ideal for applications where space is at a premium. The diode is designed to be installed on the circuit board of the device it is protecting. This allows for quick and easy installation and removal.

The diode is rated for a peak-pulse power dissipation of 1.3KW and a non-repetitive peak pulse current of 5KA. This makes it suitable for applications that require protection from over-voltage and rapid spikes of energy. The device has a maximum operating frequency of 150MHz, making it suitable for the protection of high-speed circuitry. It is also designed to be resistant to ESD (electrostatic discharge) and other transient phenomena.

The D1213A-04MR-13 is designed for use in electrical and electronic equipment operating at voltages up to 20V. It is also designed to function at temperatures between −55°C and 125°C. This makes it suitable for use in a variety of applications, from low-temperature storage to high-temperature operations and conditions.

Working Principle

The working principle of the D1213A-04MR-13 is based on the fact that it is a reverse-biased diode. When the voltage on its cathode exceeds that of its anode, it starts to conduct. This action causes the diode to quickly absorb energy, thereby limiting the voltage on the protected circuitry and preventing over-voltage.

The D1213A-04MR-13 has a reverse stand-off voltage of 17V. This means that, when the voltage on the protected circuit exceeds 17V, the diode will start to conduct. When this happens, the diode will start absorbing energy, thereby protecting the circuit from over-voltage. This protection continues until the voltage drops back below the stand-off voltage, at which point the diode stops conducting.

The D1213A-04MR-13 also features a low capacitance design which helps to reduce the chance of voltage transients affecting the protected circuit. This design also helps to reduce the risk of interference from other devices in the same circuit.

In summary, the D1213A-04MR-13 is a small, fast-response TVS diode designed for use in high-speed applications where space is at a premium. It is rated for a peak-pulse power dissipation of 1.3KW and a non-repetitive peak pulse current of 5KA. It is designed to protect circuits from over-voltage and rapid spikes of energy. Its working principle is based on the fact that it is a reverse-biased diode, and it features a low capacitance design to reduce the risk of interference from other devices in the same circuit.
