Application Field and Working Principle of SMBJ110CAE3/TR13 TVS - Diodes

Transient Voltage Suppressor diodes - more commonly known as TVS diodes - are a type of semiconductor element used to protect circuits from severe voltage aberrations or transients. TVS diodes are small, fast, and highly effective, and are often utilized in automotive, computer, communication, and other electronic applications. The SMBJ110CAE3/TR13 TVS diodes are widely used in a range of such applications, owing to their effectiveness in protecting circuits from dangerous voltage fluctuations.

This type of TVS diode employ a fast-acting polymeric construction, and are suitable for use in circuits, with a peak pulse power of 110 watts. These diodes are currently available in a variety of packages, including Leadless Chip Carriers, and Wettable Flanks.

Applications of SMBJ110CAE3/TR13 Diodes

The SMBJ110CAE3/TR13 diodes are popular for use in vibration and shock protection, precision differential measurements and sensing, consumer electronics, industrial DC/DC converters, Telecommunications networks, and automotive power circuits, such as lighting, door locks, and communications. In automotive applications, these diodes can also protect against Reverse Battery and Load Dump isolation. Additionally, since these diodes have a fast response time of about 8 ns typical, they are ideal for use in Power-over-Ethernet (PoE) networks and data line protection from Electrostatic Discharge (ESD), Lightning, and Power-Cross conditions.

Working Principle

The fundamental principle of working of the SMBJ110CAE3/TR13 diode is similar to the operation of a two-terminal device, like a diode. However, these diodes have an additional third terminal associated with the anode of the diode. This third terminal helps to limit the electrical potential across the diode, thereby protecting any device which is connected in series to it. When the voltage across the diode rises above a certain predetermined level, the TVS diode turns on, allowing a precise amount of current to discharge. This current limits the voltage across the device, thus providing transient protection.

Benefits of Using SMBJ110CAE3/TR13

The SMBJ110CAE3/TR13 TVS diodes utilize a highly efficient “D-Pak” style package, and are available for use in variety of applications, with a surge current rating of 140 amperes (Ipp). The SMBJ110CAE3/TR13 diodes provide an efficient, effective, and low-cost solution for transient voltage suppression. Additionally, when coupled with an IC or MOSFET, these devices allow efficient integration of TVS protection in circuits.
