For many circuits, the appearance of transient overcurrent caused by lightning or other high power activities will cause serious harm to products and peripheral equipment. One way to solve this problem is to install transient voltage suppressors (TVS), also known as suppressing diodes, as protective components in a circuit. The B72214S1140K102 is an example of this type of product.

The B72214S1140K102 is a Transient Voltage Suppressor designed specifically to protect against common mode power surges. It is a two-terminal device with a zinc oxide based ceramic body, which can withstand temperatures ranging from -55°C to 125°C. The component is also designed for compatibility with automated assembly processes, with its support for surface mount technology (SMT). As for voltage ratings, its peak pulse power dissipated on an 8/20μs pulse waveform is rated at 1500W, in line with the voltage range of 14V/ 14V (K-Code Type).

Working Principle

When the input device is subject to excessive voltage or current during a transient event, the B72214S1140K102 utilizes its zinc oxide based ceramic body to reduce the transient voltage. This is the same as when a pair of back-to-back zener diodes is used – a positive zener acts like a switch, turning on when the voltage increases beyond a certain threshold, and a negative zener turns on when the voltage decreases below a certain threshold. The B72214S1140K102 operates in this manner, clamping the voltage between its two terminals when the specified voltage threshold is exceeded, preventing further damage to the circuit.

Application Field

The B72214S1140K102 is suitable for use in many applications where overvoltage protection is needed. Its low capacitance makes it suitable for use in circuit designs which require high-speed signal protection. It is also suitable for signal line protection in communication and networking apparatus; protection of data and control lines; protection of input circuits of microcomputers and PICs; and protection of telecommunication circuits. The component is also suitable for use in any circuit which requires overvoltage protection and can handle rapid transient currents.

Conclusion

The B72214S1140K102 is a Transient Voltage Suppressor which can provide reliable protection against transient events. The component is designed for easy incorporation into circuit designs which require overvoltage protection, and is suitable for use in applications such as communication and networking apparatus, input circuits of microcomputers and PICs, and telecommunication circuits.
