Introduction to CMMR1-02 TR

CMMR1-02 TR, also called a Single Rectifier Diode is a component used to allow current in one direction, while preventing it from flowing in the opposite direction. It has two main functions in electronic circuits: rectification and voltage regulation.

Applications of the CMMR1-02 TR

The CMMR1-02 TR is mainly used for converting alternating current (AC) into direct current (DC) in a power supply. As such, it is often used in switched-mode power supplies and computer power supplies.The CMMR1-02 TR is also used in communications devices and audio circuits to protect components from voltage spikes as well as voltage and current surges. It can also be used as an excellent voltage regulator, since it can limit the amount of current that flows through it.

Working Principle of the CMMR1-02 TR

The CMMR1-02 TR relies on a semiconductor PN junction to allow current to flow in one direction, while preventing it from flowing in the other. The semiconductor is composed of two doped layers of silicon, which are negatively charged on one side and positively charged on the other. This creates a potential barrier between the two layers, which causes a diode to act as a one-way gate and only allow current in one direction.When the anode side of the diode is at a higher voltage than the cathode side, current will flow from the anode to the cathode. This is known as the forward bias. When the anode side is at a lower voltage than the cathode side, current will not flow. This is known as the reverse bias. The CMMR1-02 TR also has a temperature coefficient, which is a measure of how much the diode’s forward voltage drop will change in a given temperature range. It has a fairly low temperature coefficient, meaning that it is less prone to malfunction due to changes in temperature.

Conclusion

The CMMR1-02 TR is a single rectifier diode, which is mainly used for converting AC to DC voltage in power supplies and protecting components from voltage spikes, surges and over-currents. It relies on a PN junction which only allows current to flow in one direction and has a relatively low temperature coefficient.
