1PMT4112C/TR7 is a small signal Zener diode mainly applied in electronic devices. It has been widely used in consumer electronics, precision electrical instrument and information electronics industries. 1PMT4112C/TR7 is the integrated circuit of a single Zener diode with low operating voltage and low operating current, which makes it ideal for low-voltage, low-current applications.

1PMT4112C/TR7 is usually used for voltage regulation in a circuit, for example, the series-parallel circuit, the voltage divider, and the voltage regulator. It is also used as protection against over-voltage in a circuit, such as a power supply circuit. 1PMT4112C/TR7 can also be used in circuits as an anti-static protection diode or as a clipping diode in oscillator circuits.

The working principle of 1PMT4112C/TR7 is that when a voltage is applied to the anode and cathode, the current flows from the anode to the cathode, forming a reverse-biased diode. When the voltage reaches the Zener breakdown voltage, the current is increased significantly and the voltage across the diode will stay the same. This voltage is called the Zener voltage or Zener level and can be adjusted by changing the Zener doping ib the diode.

The main feature of 1PMT4112C/TR7 is its low voltage and low current. It is ideal for electrical applications requiring low voltages, such as in series-parallel circuits and voltage dividers. It has an operating voltage range of 3.2V to 5.6V, and a maximum operating current of 200mA. 1PMT4112C/TR7 has a standard capacitance of 1200pF, a Zener voltage tolerance of 5%, and a low series resistance of 5Ω. The relatively low voltage makes it very useful for applications requiring low switching points, such as protection against over-voltage in power supply circuits.
