A 3EZ7.5DE3/TR8 is a single Zener diode rated up to 500 mW, with a breakdown voltage of 7.5 volts – plus or minus 5% and a temperature coefficient of 15 ppm/°C.

These types of diodes find application as reference elements in low voltage regulator circuits. As a Zener diode, it is frequently used to regulate the output voltage of power supply units, in order to protect against overvoltage.

The 3EZ7.5DE3/TR8 is a SOD-323 (Small Outline Diode) device. It has a very low profile package and thus is typically used in high-density surface mount designs.

The working principle behind the 3EZ7.5DE3/TR8 is relatively simple. It is a semiconductor junction diode designed to operate in the reverse-bias mode. This allows it to break the normal one-way current flow of a diode, allowing current to flow in the reverse direction, thus causing a voltage drop.

In a typical application, the 3EZ7.5DE3/TR8 will be placed in series with the output of a power supply in order to provide an adjustable voltage output. The voltage is adjusted by changing the current into the diode, allowing the output voltage to drop above the breakdown voltage. In this way, the output of the power supply is regulated.

The 3EZ7.5DE3/TR8 also has its uses in noise suppression circuits, where it is used to suppress high frequency noise due to its unidirectional nature. The diode is able to attenuate the noise without interrupting the normal DC voltage of the circuit.

Overall, the 3EZ7.5DE3/TR8 is an ideal choice for applications looking for a low profile, yet highly efficient, Zener diode. Utilizing a low voltage with a breakdown voltage of 7.5 volts, it is an ideal solution for both high-density surface mount designs and noise suppression circuits.
