BZM55C47-TR3

The BZM55C47-TR3 is a single Zener diode manufactured by NXP Semiconductor. It is a part of a series of products within the semiconductor industry that is designed to provide stable voltage regulation and reliable electrical isolation within circuits. The device is typically used in a variety of industrial, automotive, and consumer electronics applications, such as in the power supply, cable modem, and mobile phone circuits.

The BZM55C47-TR3 is a low-power Zener diode that offers a current breakdown voltage of 5.7 to 7.0 volts and a power dissipation of up to 200 milliwatts. It has a maximum zener voltage of 51 volts, a maximum forward voltage of 1.5 volts, and a maximum reverse current of 600 microamps. The device’s maximum proximate reverse breakdown voltage is specified as 5.7 to 7.0 volts. Its maximum reverse current temperature coefficient is -5.5% to -6.5%.

The working principle of the BZM55C47-TR3 relies on the diode’s application of Zener voltage regulation. This involves the device controlling the voltage of a circuit by allowing a controlled amount of current to pass through it when the voltage exceeds the specified zener voltage or threshold. This is performed by the device regulating the flow of majority current, which is adjusted according to the voltage of the circuit being regulated. Once the zener voltage has been exceeded, the controller kicks in and reduces the current to the appropriate level.

This is crucial to circuit stability as a sudden increase in voltage beyond the threshold can cause significant damage. The Zener diode is a much more reliable and cost-efficient solution to maintaining voltage regulation in a circuit, as the majority of the current flows through the device at all times.

In addition to voltage regulation, the BZM55C47-TR3 can also be used in applications that require electrical isolation. By utilizing the unique characteristics of the Zener diode, the device is capable of completely isolating the input and output circuits, thus preventing any cross-currents that may occur when signals are transmitted between the two circuits. This is especially useful in automotive and consumer electronics applications, where electrical isolation is often required for device protection.

Overall, the BZM55C47-TR3 is a low-power Zener diode from NXP Semiconductor that offers reliable voltage regulation and electrical isolation in a variety of applications. It is ideal for automotive, industrial, and consumer electronics circuits due to its ability to effectively control the voltage of the circuit and to provide protection from unexpected voltage spikes. In addition, the device also offers electrical isolation, thus preventing any cross-currents that may occur when two or more circuits are interconnected.
