SMDJ13C

TVS-Diodes are widely used components for protecting electronic equipments against transient surge voltage situations. It is an important device to protect equipment from over-voltage, ESD, EFT, surges and to reduce downtime of the equipment in the industries. SMDJ13C is a widely used unidirectional TVS-Diode, which provides robust electrical over-voltage protection devices for many different types of applications.

The SMDJ13C consists of two zener diodes connected in series. The diode has a low breakdown voltage and a low series inductance. The diode can withstand up to 13 A peak pulses current. The part number for the device points to its breakdown voltage which is rated at 13 V at 1 A. The part is in a SMA DO-214AC package, which is a veteran in the electronics industry.

The main application of the SMDJ13C is in AC and DC line protection for equipments and systems such as computers, TVs, lab equipment, medical equipments, communications systems etc. The SMDJ13C can also be used to protect low voltage systems such as those in automobiles and aircrafts. The element can be used to protect against over-voltage and over-current conditions in the systems.

The working principle of the SMDJ13C is very similar to other TVS-diodes. It uses a unique two zener diode configuration. The two zener diodes in parallel, with the positive diode connection connected to a higher voltage rail than the negative diode connection. When the input voltage exceeds the breakdown voltage, current flows through the diode. When voltage drops below the breakdown voltage, the diode snaps back to its off state stopping current from flowing through it. This helps protect the system by providing a nonlinear clamping action in a system.

TVS-Diodes are an essential part of any electronics system or equipment as they provide protection against transients and help to reduce system downtime. The SMDJ13C is a commonly used device for protecting systems from over-voltage and over-current conditions and provides robust electrical protection for many different types of applications. The device is small, inexpensive, and very reliable, making it an ideal choice for many system designers.
