SMBJ24A-TR Application Field and Working Principle

SMBJ24A-TR belongs to the TVS - Diodes category, where it is used in protecting devices from overvoltage transients. It is a type of unidirectional voltage-clamping device, designed to limit the transient voltage ranging from 5.5V to 24V in single-line protection. The device is comprised of a state-of-the-art silicon avalanche diode and two breakover zener diodes, resulting in an optimized lightning performance.

Features of SMBJ24A-TR

• Flame retardant UL 94V-0-rated construction
• Breakthrough voltage from 5.5V to 24V
• Lead-free solders for environmental friendly

Application Field of SMBJ24A-TR

SMBJ24A-TR is an ideal protection device for many applications such as industrial and automotive electronics circuits, computer, peripheral, LAN lines, telecommunication, consumer electronics, battery powered applications, set-top boxes, AC/DC adapters and many others. The device is suitable for both low and high power usage.

Working Principle of SMBJ24A-TR

SMBJ24A-TR works on a simple premise: it shorts out any surges in power or potentially damaging effects beyond the specified level. This means that if a voltage higher than 24V were to enter a circuit, the SMBJ24A-TR is designed to short circuit the power supply and prevent the connection. This provides protection from electrical transients, and creates a safe environment for the connected component.

SMBJ24A-TR operates by using a number of different elements. The first are the two breakover zener diodes, which are used to provide voltage regulation. When a surge in power exceeds the standard level, these breakover diodes start to conduct electricity, resulting in a rapid increase in voltage. This voltage increase then triggers the avalanche diode, which limits the amount of voltage entering the circuit, protecting it from potential damage.

Conclusion

SMBJ24A-TR is an extremely useful device for protecting circuits from potentially damaging electrical transients. By using a combination of two breakover zener diodes and an avalanche diode, this TVS - Diode is able to limit the voltage passing through a circuit and safeguard connected components. The device is often used in industrial and automotive electronics, computer peripherals, batteries, AC/DC adapters, and much more.
