MM3Z15VT1 Discrete Semiconductor Products

The MM3Z15VT1 is a small-signal silicon epitaxial Zener diode which is widely used in a variety of industries and applications. With the high voltage breakdown levels and low reverse leakage current, this diode provides exceptional performance in low current and low power applications.

The most popular application for the MM3Z15VT1 is to serve as a voltage regulator. It allows a circuit to maintain a constant voltage under varying loads or conditions. This diode can be used for providing limited overvoltage protection for circuits and equipment. The Zener diode characteristics allows for the applied voltage to be clamped at the Zener voltage and not rise above it.

Another common application of the MM3Z15VT1 is to provide a bias voltage in a circuit, serving to bandgap voltage stabilization. The Zener voltage of the diode prevents an excessive current from flowing against it and avoids the problems associated with an undershoot or overshoot of the diode’s voltage level.

The MM3Z15VT1 is also used for voltage switching and for better signal performance ripple suppression in power supply circuits. Its non-Inductive construction is suitable for low inductance noise sensitive applications. Other applications include buffering, current limiting, waveform clamping, and voltage clamping.

The MM3Z15VT1 works on the principle of semiconductor junction breakdown. A low voltage is applied across a junction and the voltage at which conduction begins to occur is called the Zener voltage. The current flowing through the diode is limited by the internal resistance of the junction and the external resistor. The Zener diode will start to get a reverse breakdown once the reverse voltage reaches the Zener voltage, which is indicated on the diode’s data sheet.

When the reverse voltage drops below this value, the current is still conducted by the diode, thanks to the charge carriers stored in the depleted region. The leakage current is called the reverse leakage current, which is also shown on the data sheet. The MM3Z15VT1 is designed with a high Zener voltage and low reverse leakages currents for optimum performance under different conditions and applications.

This diode has a maximum power dissipation of 200mW and a maximum reverse voltage of 15V. It also features excellent reliability with a wide range of operation temperatures. The package for the MM3Z15VT1 is a SOD323, a small surface-mount package typically used for electronic components that require a low profile.

In conclusion, the MM3Z15VT1 is a versatile Zener diode and can be found in a variety of applications and industries. It offers a wide range of current, voltage and power capabilities and is suitable for use in both high and low power circuits. Its unique construction allows it to provide superior performance in high voltage and low power applications. Thanks to its small SOD323 package, the MM3Z15VT1 is easy to integrate into all types of circuits.
