TZMC2V7-M-18 is a type of single Zener diode, widely used in many types of applications. Commonly seen as discrete components or in various packages, these diodes are frequently used to provide a regulated or a reference voltage in systems and circuits. The device is available in several capacitance ranges, levels, and common formats.

Device Overview

TZMC2V7-M-18 is a common 6-pin single diode with a maximum reverse breakdown voltage of about 2 volts and a maximum allowable power dissipation of 0.75 watts. The device also featrues a maximum reverse recovery current of 5 milliamps. The Zener junction has a temperature coefficient of about 5.6 mV/deg C and a minimum operating temperature of -40-deg C.

Applications

Generally speaking, TZMC2V7-M-18 can be used in a wide variety of applications where a low voltage, stable voltage reference is desired. Zener diodes like the TZMC2V7-M-18 may be used in linear regulation systems, overvoltage protection systems, and peak detectors. This device also can be used to provide a fixed voltage source in series with a diode or transistor. The device may appear in voltage regulators, series-regulator circuits, other temperature compensating circuits, and DC power supplies.

Working Principle

A Zener diode, including TZMC2V7-M-18, works by allowing a current to flow in the forward direction when the outer cathode is more positive than the inner anode terminal. The Zener breakdown voltage is the voltage that the diode will remain in a “reverse-breakdown” mode when a given current is applied. It is during this period that the diode can be used to regulate the voltage.

When the voltage across the diode is greater than the breakdown voltage, current will thin out in the reverse direction. The larger this difference between the anode voltage and cathode voltage, the higher the diodes reverse-breakdown voltage will become. A Zener diode typically has a low threshold of current that flows through it even at voltages under its breakdown voltage, allowing the diode to be used as a voltage regulator.

Conclusion

TZMC2V7-M-18 is a robust, reliable single diode that is commonly used for applications requiring a stable voltage reference. Its 6-pin single diode design allows for easy integration into a variety of circuits, and its low power dissipation is crucial in systems where power consumption must be minimized. The device works by allowing a current to flow in the forward direction when the outer cathode is more positive than the inner anode terminal and by having a low threshold of current that flows through it even at voltages under its breakdown voltage, allowing the diode to be used as a voltage regulator.
