2EZ82D2E3/TR12

A 2EZ82D2E3/TR12 diode is a maximum power dissipation, low-voltage Zener diode. It is a single-junction diode which has a reverse breakdown voltage of 12 volts. It is most commonly used to provide a regulated, low-voltage power supply from a high-voltage input. When reverse-biased, according to the Silicon PN junction theory, this diode will have its reverse current flowing through it limited to a very small value. Once the reverse biased voltage reaches the point at which the diode’s breakdown occurs, usually denoted by the Zener voltage or V_Z, the reverse current increases greatly. This can be used to provide a regulated output voltage. As the input voltage increases, the forward current also increases, which is limited and regulated by the voltage source.

The 2EZ82D2E3/TR12 diode has a maximum power rating of 200 mW, and the maximum peak reverse voltage is 12V. It has a reverse voltage tolerance of up to 15 volts. The maximum forward current is also fairly low, at 25 mA. Additionally, the reverse current is specified to be 10 μA, with a maximum temperature rise of 50 K when operated at the specified operating temperature. In general, these diodes are suitable for applications that require low voltage operation, such as in power supplies and voltage regulators, as well as for AC to DC rectification.

The 2EZ82D2E3/TR12 diode’s main application is voltage regulation. The diode behaves as a Zener diode (or breakdown diode), which is a type of diode that limits the voltage to a certain degree in a circuit. When an electron is incoming, its potential energy is lowered by the potential downwards. If it reaches the breakdown voltage, the diode will become a low-resistance element, and with a low-resistance element, the current is limited and the voltage is kept constant. This is the basic principle of Zener diodes.

The 2EZ82D2E3/TR12 is ideal for low voltage regulation, as it has a wide range of reverse voltage tolerance. The reduced forward voltage drop of the diode gives it a high efficiency and improves its performance in low voltage applications. The wide range also makes it very reliable in various temperature and voltage conditions.

Overall, the 2EZ82D2E3/TR12 diode is a great solution to provide a low-voltage, regulated power supply from a high-voltage input. It is ideal for applications where a low-voltage output is desired, such as in power supplies and voltage regulators, and for AC to DC rectification. With its low reverse current, wide reverse voltage tolerance and low forward voltage drop, this diode is well suited for these applications and can provide reliable performance.
