Diodes - Zener - Single category include BZM55C2V4-TR, a type of device specifically designed to provide a voltage reference and create low-voltage power supply regulation. BZM55C2V4-TR diodes have a wide range of applications, primarily due to the handling and control of voltages in electronic circuits.

BZM55C2V4-TR diodes have a reverse breakdown voltage rating of 4V with an operating temperature range of -55 to 150 °C. They are made with a glass body, and are usually packaged in a SOT-23-3 package form, with a maximum reverse voltage drop of 4V. The maximum forward current is 500mA and the power dissipation is 350mW. This type of diode is often used when a voltage reference needs to be held at a constant level.

The working principle of the BZM55C2V4-TR diode is based on Zener breakdown. As voltage is applied to the diode in the reverse direction, electrons at the junction accelerate from the cathode to the anode until the electric field is strong enough to provide collision ionization, creating an avalanche of charge carriers that increases the current sharply. This sudden increase of current creates the breakdown voltage, which is held constant in the diode. In the case of the BZM55C2V4-TR diode, this level is 4V.

BZM55C2V4-TR diodes can be used in a variety of applications, including voltage regulation, over-voltage protection, transient voltage suppression, current regulation, and noise filtering in transient and power supplies. The BZM55C2V4-TR diode is used in voltage referencing to ensure the voltage across a load is held constant. This is particularly useful in low-voltage circuits, where the diode can be used to regulate voltage to a specific level.

In over-voltage protection circuits, the BZM55C2V4-TR diode protects sensitive components from over-voltage damage. When the voltage across the diode reaches the breakdown voltage of 4V, the current quickly increases and the voltage across the protected component is clamped to this breakdown level, protecting it from further damage.

In transient voltage suppression circuits, the BZM55C2V4-TR diode absorbs voltage spikes or transients that may overload the circuit. When the spike or transient reaches the breakdown voltage, the current increases dramatically, quickly dissipating the energy.

In current regulation circuits, the BZM55C2V4-TR diode is used to limit the current that can flow through the circuit in order to protect sensitive components. The breakdown voltage of the diode ensures that the current remains at constant levels, and also reduces power losses due to wasted heat.

Finally, the BZM55C2V4-TR diode is often used in noise filtering circuits to reduce electromagnetic interference. This diode can absorb transients and noise signals, helping to reduce signal distortion. The diode can also be used in high-frequency switching applications, where its low capacitance can help reduce the amount of power required to switch circuits.

BZM55C2V4-TR diodes are a versatile device, with a wide range of applications. They are ideal for use in low-voltage circuits, as voltage references or for over-voltage protection and current regulation. In addition, these devices can be used for noise filtering and in high-frequency switching applications, helping to reduce power consumption and signal distortion.
