Introduction to TVS (Transient Voltage Suppressor) Diodes – CDNBS16-T03C

The CDNBS16-T03C is a non-polarized transistor voltage suppressor (TVS) diode, which is used to protect against high transient voltages. TVS diode, as the name suggests, is a kind of device designed to protect the connected circuit from potential damage due to high voltage spikes. The CDNBS16-T03C is specifically designed to provide protection from peak, repetitive transients, also known as Electrostatic Discharge (ESD).

Application Fields and Working Principles of CDNBS16-T03C

The CDNBS16-T03C is suitable for sensitive electronic components where protection from electrical transient pulses is desired. The device has an operating voltage of 5.5 V, a working current of 0.443 A, and a peak surge current of 17.35 A. The device can be used as a single line protection for telephone lines, ISDN lines, modem lines, personal computers, and other communication equipment. When a transient pulse is present, the CDNBS16-T03C will conduct current, thus providing protection for the connected circuit. The device has a break-over voltage of 11 V, which means that the device begins to conduct current when the applied voltage reaches this level. When the transient pulse ends, the device stops conducting current and return to its non-conductive state, allowing voltage of the connected circuit to resume its normal operation. The device’s maximum peak pulse voltage is 20 V, and its maximum clamping voltage is 10.8 V. The device also has a low capacitance, which is important for high speed circuits. In addition, the device features a reverse connection protection, meaning that the device does not conduct current if it is reversely connected. This is an important feature for communication equipment, where incorrect installation may lead to damage of the device.

Conclusion

The CDNBS16-T03C is a non-polarized transistor voltage suppressor (TVS) diode, which is designed to protect sensitive electronic components from potential damage due to high voltage spikes. The device has a break-over voltage of 11 V, a peak surge current of 17.35 A, and a maximum peak pulse voltage of 20 V. The device can be used as a single line protection for various communication equipment, and has a low capacitance and reverse connection protection.
