CDNBS16-T12C

TVS diodes are a crucial component of many electronics. They protect against over-voltage caused by electromagnetic interference (EMI) and transients in order to reduce component damages and system malfunctions. The CDNBS16-T12C is a type of transient voltage suppressor (TVS), designed with a variety of features to provide superior and robust protection. This article covers the application field and working principles of CDNBS16-T12C.

Application Field

CDNBS16-T12C has a variety of applications in a broad range of industries. It is often used in automotive applications since it is designed to tolerate high temperatures and provide reliable protection. It has a high clamping voltage of 737V, making it suitable for power supplies, inverters, and solar converters. In industrial electronics, it serves as a reliable surge protection device for I/O ports, instruments, and signal lines. Its rated peak pulse power provides robust protection to prevent system damages and malfunctions in industrial and consumer electronics.

Working Principle

CDNBS16-T12C operates by dissipating the excessive voltage through a voltage dependent resistor (VDR). The VDR is comprised of a semiconductor layer with a high conductivity. When an over-voltage is present, the resistance of the VDR significantly decreases, causing the over-voltage to be dissipated by a low resistance path, thus providing protection to the system. Under this situation, the VDR absorbs the excessive voltage and dissipates it into heat.

The CDNBS16-T12C features low capacitance and low thermal resistance. Its robust design allows for componets to sustain high power transients without degrading its performance. Genenrally, it has a maximum continuous working voltage of 6V and a peak pulse power dissipation of 1.2kW (10/1000μs).

Conclusion

The CDNBS16-T12C provides reliable surge and EMI protection for various automotive, industrial, and consumer applications. It is suited for a wide range of protection, particularly in high temperature environments, as its low capacitance and thermal resistance provide superior protection for systems. The working principle involves dissipating over-voltage through a voltage dependent resistor, thus preventing system malfunctions and damages.
