1PMT5931CE3/TR7 Application Field and Working Principle

The 1PMT5931CE3/TR7 is a zener diode from the single category suited for a variety of electronic applications. It is a three terminal semiconductor device made of a doped p-type region between n-type substrate and a n-type connecting region. It is a voltage regulating diode that acts as a short circuit when the current passing through it is greater than its rated current. The breakdown voltage of 1PMT5931CE3/TR7 can be adjusted by selecting a specific doping level.

The breakdown voltage of 1PMT5931CE3/TR7 ranges from 7.95 V to 8.05 V and the power dissipation is 250 mW. Its peak reverse current is greater than 20 mA and its forward voltage is 1.2 V. Its protective coating is glass passivated, which provides an electric insulation layer to protect the device from heat and electrical shock. Its package includes a vacuumized glass envelope for added protection.

The working principle of 1PMT5931CE3/TR7 is simple. When the electric current passing through it is greater than its rated current, the junction breaks down and the device acts as a short circuit. To prevent such a breakdown, an external resistance is connected between the anode and cathode to limit the current passing through. In addition, when the voltage drop on either side is greater than the breakdown voltage, the device becomes forward biased and acts as a diode, allowing the current to flow in only one direction.
