SMBJ220E3/TR13 Datasheet/PDFThe SMBJ220E3/TR13 is a unidirectional voltage suppressor device providing 500W peak pulse power per line on printed circuit boards. This device clamps the voltage of direct current lines in the circuit and prevents overvoltage conditions to ensure a safe operation. This particular device is constructed of a group of Transient Voltage Suppressor Diodes (TVS) which are widely used for protecting electronic circuits from damage by surges in the power lines that would otherwise cause the breakdown of the component.
Application field of SMBJ220E3/TR13
The SMBJ220E3/TR13 is widely used in the information, telecommunications, mechanical, medical, consumer electronics and automotive industries. The applications have shifted from ensuring the safety of electronic components to protecting the entire system. In the automotive industry, TVS diodes are especially important in protecting the automotive control systems, ECUs, sensor boards and telecommunications systems from electrical spike damage. Electrical spikes are created by a wide variety of sources like electrostatic discharge, inductive loads, load dumping, engine stalling, contact relays, cellular communications, electrical transient and power inverters.
Working Principle of SMBJ220E3/TR13
The working principle of the SMBJ220E3/TR13 is simple. The TVS diodes are connected in parallel with the circuit to be protected. When an overvoltage condition occurs, the SMBJ220E3/TR13 will respond by clamping the voltage to a safe level. The TVS diodes are made up of a semiconductor junction and a Zener diode junction. The semiconductor junction is normally biased in the reverse direction, preventing current from flowing. When an overvoltage condition occurs, the Zener diode junction becomes forward biassed, allowing the current to flow through the device. This causes the voltage on the device to be clamped to a safe level. This prevents the device from being damaged by an overvoltage condition.
Advantages of SMBJ220E3/TR13
The SMBJ220E3/TR13 offers several advantages over traditional methods of protecting electronic components from overload and electrical spikes. It is able to withstand high levels of peak power, with a peak pulse power of 500W per line. This allows the device to protect a much larger area from electrical spikes and surges. It also offers excellent ESD (electrostatic discharge) protection, with an electrostatic discharge immunity level of up to 2 kV. This ensures that your components are protected from even the most extreme electrostatically charged objects and conditions. Finally, the SMBJ220E3/TR13 is available in a wide range of packages and sizes, making it easy to find one that meets your application requirements.
Conclusion
The SMBJ220E3/TR13 is a unidirectional voltage suppressor device that is widely used for protecting electronic components from overload and electrical spike damage. It is able to withstand high levels of peak power, offers excellent ESD protection, and is available in a wide range of packages and sizes. The SMBJ220E3/TR13 is an ideal choice for anyone looking for an effective and affordable way of protecting their electronics.
