Introduction to the BZX84C2V7-TP

The BZX84C2V7-TP is a single-terminal diode, manufactured by NXP Semiconductor in a variety of different packages. It is used as a zener reference in applications such as audio-visual equipment, case voltage regulators and voltage limiters. The device is designed to suppress power supply noise by providing stable reference voltages and low dynamic resistance, which prevents any overvoltage conditions from occurring. It can also be used for short-term overvoltage protection, when connected to long-term storage devices.

Working Principle

The BZX84C2V7-TP is a silicon zener diode with a breakdown voltage of 2.7V and a static resistance of less than 200mΩ. The device works by actively regulating a defined output voltage and providing overvoltage protection. When connected to a power source, the diode begins to conduct at the point when the power reaches the breakdown voltage, allowing excess current to be diverted around the protected components and fixing the output voltage at a constant level. The device handles this operation by constructing a Zener barrier which is designed to generate a constant voltage reference and rapidly limit current when an excessive input voltage is applied.

Conclusion

The BZX84C2V7-TP is an ideal single-terminal diode for applications requiring a stable 2.7V voltage reference, such as automotive audio-visual equipment and case voltage regulators. It features a low dynamic resistance, which prevents any overvoltage conditions, and has a maximum peak forward surge current rating of 100A. The diode works by actively regulating a defined output voltage and providing overvoltage protection by constructing a Zener barrier and rapidly limit current when an excessive input voltage is applied.
