Working Principle

The working principle of BZD17C220P MTG is not complicated. It is a low-power diode with a PN junction, which utilizes the junction’s values of forward voltage and reverse voltage. When a forward voltage is applied to the PN junction, it creates a knee current and the diode starts to conduct. At the beginning, there is a very small current in the diode, so the voltage drop is very small. As the current increases, the forward voltage of the diode is increased and the forward voltage reaches a constant.

When a reverse voltage is applied to the PN junction, due to the existence of space charge region, the reverse current is relatively small and the reversed biased voltage reaches a constant value. This become the reverse breakdown voltage of this diode. BZD17C220P MTG is used in applications with the reverse breakdown voltage of various values, such as 6.2V and 7.8V. The higher the breakdown voltage, the higher reverse bias voltage it can withstand.

In addition, BZD17C220P MTG also has a high reverse pulse current tolerance, which is beneficial for protecting circuits efficiently. It also has a robust zener diode design, meaning it does not fail when it experiences high reverse voltages or high temperature fluctuations. Its temperature coefficient is also low, which ensures a reliable performance across the operating temperature range.

Conclusion

To sum up, BZD17C220P MTG is a low-power diode with a PN junction, which is applicable in the fields of computers, network systems, communication systems and instrumentations. Its working principle is relatively simple, as it utilizes the junction’s values of forward voltage and reverse voltage to create a forward knee current what provides protection for circuits. With its excellent performance, stable quality and high reliability, BZD17C220P MTG is an important part of many high and low voltage power conversion circuits.
