TZMC39-GS18

Diodes - Zener - Single: TZMC39-GS18 Application Field and Working Principle

The TZMC39-GS18 is a single diode designed to operate as a Zener diode in a variety of circuit applications. It is used as a shunt regulator to protect from overvoltages, to regulate bias voltage, and as a clipper for AC signals. It is also used for voltage clamping and for limiting the current in circuits.

In general, Zener diodes are manufactured in various voltage and power ratings, typically 2.5 to 200 volts and 0.2 to 5 Watts. This model is rated 3.9 volts, with a maximum power dissipation of 18 milliwatts.

Application Field

The TZMC39-GS18 is used in a variety of applications, from protecting electronic components from overvoltage to providing a stable DC output voltage. It can be used in shunt regulator circuits, voltage regulator circuits, AC clipper circuits, and current limiter circuits.

The TZMC39-GS18 is well-suited for applications where a low-voltage Zener diode is required. It is suitable for power supplies, instrumentation, data acquisition systems, and other highly sensitive circuitry. It is particularly useful in small circuits where space is at a premium, since it is a small diode with a very low power rating.

Working Principle

The TZMC39-GS18 operates using the Zener effect. When connected in a circuit, it allows current to flow in one direction, and absorbs any voltage above the Zener voltage. This means that when it is connected in series with a load, the voltage will remain at a constant level, no matter how much current is drawn from the load.

When the voltage across the diode exceeds the Zener breakdown voltage, the excess voltage is absorbed and dissipated as heat, protecting the device from damage. The voltage drop across the diode is dependent on the current through the diode, making the voltage regulation dependent on the current regulation.

In addition, the diode provides protection from overvoltage by limiting the voltage that can be applied to the circuit and provides a reliable source of constant DC voltage. This makes it an ideal device for use in power supplies and other DC circuits.

Conclusion

The TZMC39-GS18 is a single Zener diode capable of operating at a variety of voltages and current levels. It is well-suited for applications where a Zener diode of low-voltage and low-power is needed, such as power supplies, instrumentation, and data acquisition systems. It operates using the Zener effect, providing constant DC output voltage and protection from overvoltage.
