BZM55C11-TR

Diodes play an important role in daily life due to the immense number of electronic circuits that require them. As such, many different types of diodes exist, tailored for a variety of applications. A single Zener diode whose part number is BZM55C11-TR both has a specific application field and a precise working principle.

Application Field

The BZM55C11-TR is a diode commonly used when the user requires precise voltage regulation with high temperature performance. This diode is widely used in the fields of automotive electronics, medical electronics, portable electronics, computers and other small electronic devices. It is frequently used in rectifier circuits and to protect devices against voltage spikes.

Working Principle

Zener diodes in general operate in a specific way. By hooking up a Zener diode in reverse bias across a component, it introduces a diode leakage current that can be maintained at a certain level in order to provide a stable voltage output. It can be used to construct an adjustable voltage source from the component, by making use of the principle of reverse breakdown: whenever the voltage increases beyond its predetermined threshold, the Zener diode conducts and keeps the voltage across it constant, thus preventing any fluctuations. It is this quick response that makes Zener diodes very desirable.

In the case of the BZM55C11-TR, it has a reverse voltage of 11V and a power dissipation of 250mW in 85^oC. In terms of stability, it offers a Low Temperature Coefficient of typically between -0.083 to 0.18mV/^oC. This helps maintain the device’s stability, even in extreme temperature conditions.

Conclusion

The BZM55C11-TR offers a useful solution for applications requiring precise voltage regulation with high temperature performance, such as automotive electronics, medical electronics, portable electronics, and computer applications.As a diode, it operates under reverse bias to maintain stable voltage output, while its low temperature coefficient and robustness against temperature fluctuations make it even more attractive.
